SSC CGL Posts for Colour Blind Candidates: Eligibility and Medical Restrictions

A candidate may discover red-green colour blindness during an eye check-up and still have clear vision for reading, computer work and everyday activities. The real confusion begins while arranging SSC CGL posts: should Income Tax Inspector, Assistant Section Officer, CBI, NIA, NCB, CBIC or another post come first?

Accessibility note: This page does not communicate eligibility through colour alone. Every evidence level also uses a letter, written label and a different border style.

Explicit Restriction The checked official document directly mentions colour blindness as a rejection ground.

Confirmation Needed The post has special standards, but colour-vision eligibility is not expressly confirmed in the checked SSC section.

Lower Documented Risk The post is outside the special annexure list or no specific colour-vision restriction was located in the checked notice.

The Two Online Answers You Should Not Trust Blindly

Students searching for SSC CGL posts for colour blind candidates often receive one of two extreme answers. Both can damage a preference list because SSC CGL recruits for many departments with different duties.

Extreme claim one “Colour blindness is allowed in every SSC CGL post.”

Extreme claim two “A colour-blind candidate cannot get any Inspector post.”

The correct question is not only, “Can I apply for SSC CGL?” The safer question is, “What does the current notice say about the exact post and what will its user department check after allotment?” An examination may accept your application provisionally while final appointment still depends on post-specific medical suitability.

Colour Vision, 6/6 Eyesight and Eye Power Are Different

These three terms are regularly mixed together. That is why a candidate with normal reading vision may be surprised by a colour-vision report, while another candidate wearing glasses may have normal colour perception.

Colour Vision

This is the ability to distinguish colours and shades. Red-green deficiency is the most common type, but colour vision can vary by type and severity.

Visual Acuity

This measures how clearly you see detail at a stated distance or near point. Values such as 6/6 and 6/9 belong to visual acuity, not to colour perception.

Eye Power and Spectacles

Prescription spectacles mainly correct refractive errors such as short-sightedness or long-sightedness. Ordinary glasses do not convert a colour-vision deficiency into normal colour vision.

The National Eye Institute explains colour blindness as seeing colours differently and says an eye doctor can use a colour plate test for diagnosis. A phone-screen test or a screenshot cannot replace a proper examination. Read the National Eye Institute explanation.

Official Evidence File: What the SSC Notice Actually Says

The SSC CGL 2026 notice was uploaded on 21 May 2026. It identifies selected CBIC, CBN, CBI, NIA, NCB and BRO posts as having special physical or medical requirements, with details in Annexure XV and Annexure XVI.

Official rules checked on: 18 July 2026

Open Official SSC Notice

Special-post list CBIC Central Excise, Examiner and Preventive Officer; Inspector and SI in CBN; SI/JIO in NCB; SI in CBI and NIA; and post(s) in BRO.

User-department test Physical and medical standards are examined by the concerned user department after final selection and nomination.

Preference risk If a selected candidate fails a post-specific standard, the notice warns that candidature can be rejected without consideration for another post.

Important reading rule If colour vision is not mentioned in a specific SSC section, this article uses the wording “not expressly stated in the checked SSC notice.” Silence is not treated as guaranteed eligibility.

Colour-Vision Evidence Map for SSC CGL Posts

A

BRO and GREF: Explicit Colour-Blindness Restriction

Explicit Restriction

Annexure XVI contains the separate medical framework for posts in the Border Roads Organisation. Under the grounds for permanent rejection, the checked notice expressly includes “cases of colour blindness.”

The current notice also states that only male candidates are eligible for BRO vacancies, if any are reported. Its post-suitability annexure identifies UDC/SSA in BRO, while the special-post clause directs candidates to the BRO physical and medical annexure.

For a candidate with confirmed colour blindness, a BRO-linked preference should therefore be treated as explicitly high risk. This BRO rule must not be copied onto every other SSC CGL department.

B

Special Standards, but Written Colour-Vision Confirmation Is Needed

Confirmation Needed

CBI Sub-Inspector

Clear acuity rule, unclear colour-vision position

The notice states distant vision of 6/6 in one eye and 6/9 in the other, near vision of 0.6 and 0.8, with or without glasses. A separate colour-vision acceptance line was not located in this section.

Action: Seek written CBI or appointing-authority confirmation before ranking it above safer options.

NIA Sub-Inspector

Do not convert the glasses line into a colour-blindness answer

NIA carries the same stated distant and near visual-acuity values and the wording “with or without glasses.” Colour-vision eligibility is not expressly confirmed in the checked NIA section.

Action: Treat it as an uncertain field preference until the department gives a clear rule.

NCB SI or JIO

Visual acuity is written; colour perception remains a separate question

The NCB section states 6/6 and 6/9 distant vision, 0.6 and 0.8 near vision, with or without glasses. The checked section does not expressly confirm colour-blind eligibility.

Action: Obtain a current departmental clarification before placing it high.

CBIC Inspector Group

Physical test is written, colour-vision acceptance is not

Central Excise, Examiner and Preventive Officer have height, chest or weight, walking and cycling standards. A separate colour-vision acceptance statement was not located in that Annexure XV subsection.

Action: Do not assume that passing PET/PST settles the departmental medical question.

Inspector and SI in CBN

Physical standards are not the complete medical file

The checked SSC section places these posts with the CBIC-style physical standards. It does not expressly state that every form of colour blindness is accepted.

Action: Confirm the current CBN medical position through an official route.

C

Posts with Lower Documented Colour-Vision Risk

Lower Documented Risk

The following office, audit, accounts, statistical and administrative titles appear in the current post list but are not named in the special physical and medical list at Paragraph 15.7. This makes them useful starting points for preference research, not automatic medical guarantees.

Administrative Group

Assistant Section Officer and Assistant posts

These titles are mainly connected with files, noting, drafting, coordination, records or administrative work, though exact duties and departments differ.

Evidence wording: Potentially safer for preference planning based on the checked SSC notice, but not an official medical guarantee.

Revenue Office Group

Income Tax Inspector, Office Superintendent and Tax Assistant in CBDT

These posts are present in the current CGL list, while Income Tax Inspector is not included in the special physical or medical list at Paragraph 15.7.

Evidence wording: Lower documented risk in the SSC notice; CBDT appointment fitness remains final.

Audit and Accounts Group

Auditor, Accountant, Junior Accountant and Divisional Accountant

These posts generally involve accounts, audit, records, vouchers, reports and related office or inspection work. They are outside the checked special-post list.

Evidence wording: Potentially safer for preference planning, subject to the specific user department.

Data and Research Group

JSO, Statistical Investigator, Research Assistant and other analytical posts

These posts can involve data, surveys, research, analysis and reports. The current notice does not place these titles in Annexure XV or XVI as special physical-test posts.

Evidence wording: Lower documented risk, but qualification and departmental fitness conditions still apply.

Clerical and Postal Group

Postal Assistant, Sorting Assistant and UDC or SSA outside BRO

These posts are not one uniform medical category. The BRO department is a clear exception and must be separated from UDC/SSA vacancies in other ministries.

Evidence wording: Department-specific; do not transfer the BRO rule to every UDC/SSA post.

Mixed Duty Group

Assistant Enforcement Officer and other field-linked posts

Some posts may mix office work with field visits or enforcement duties even when they are outside Annexure XV. A detailed colour-vision rule was not located in the checked SSC notice.

Evidence wording: Rule not located; obtain departmental confirmation instead of treating absence as approval.

SSC CGL Post-Wise Colour-Vision Evidence Matrix

This matrix deliberately avoids a simple “allowed/not allowed” column. It shows what the checked documents support and where a candidate still needs written confirmation.

SSC CGL Post	Special Medical Annexure	Colour Blindness Expressly Mentioned?	Other Vision Standard	Evidence Status	Preference Advice
UDC/SSA or applicable post in BRO	Annexure XVI	Yes. Listed under grounds for permanent rejection.	BRO visual-acuity and spectacle provisions also apply.	Explicit Restriction	Treat as high risk for a candidate with confirmed colour blindness.
CBI Sub-Inspector	Annexure XV	Not expressly stated in the checked CBI section.	6/6 and 6/9 distant; 0.6 and 0.8 near; with or without glasses.	Written Confirmation Needed	Do not rank above safer posts without current departmental confirmation.
NIA Sub-Inspector	Annexure XV	Not expressly stated in the checked NIA section.	6/6 and 6/9 distant; 0.6 and 0.8 near; with or without glasses.	Written Confirmation Needed	Confirm the user-department medical rule before preference locking.
NCB SI or JIO	Annexure XV	Not expressly stated in the checked NCB section.	6/6 and 6/9 distant; 0.6 and 0.8 near; with or without glasses.	Written Confirmation Needed	Treat visual acuity and colour vision as separate requirements.
CBIC Central Excise, Examiner and Preventive Officer	Annexure XV	No separate colour-vision line located in the checked subsection.	No CBI-style 6/6 and 6/9 line in that physical-test subsection.	Written Confirmation Needed	Check CBIC appointment or departmental medical instructions.
Inspector and SI in CBN	Annexure XV	Not expressly confirmed in the checked physical-standard subsection.	Physical standards and walking requirements are specified.	Written Confirmation Needed	Request an official CBN clarification before ranking high.
Income Tax Inspector	Not listed in Paragraph 15.7 special-post group	No specific restriction located in the checked SSC notice.	No separate colour-vision standard stated in the checked CGL notice.	Lower Documented Risk	Potentially safer, but verify CBDT general medical fitness.
ASO and Assistant posts	Outside Paragraph 15.7 special-post group	No specific restriction located in the checked SSC notice.	Department-specific general fitness may apply.	Lower Documented Risk	Useful desk-oriented starting point; verify the allotted department.
Auditor, Accountant and Divisional Accountant	Outside Paragraph 15.7 special-post group	No specific restriction located in the checked SSC notice.	General user-department fitness remains possible.	Lower Documented Risk	Consider as practical backups after department-level verification.
AEO and other mixed-duty posts	Not in Paragraph 15.7 special-post group	Detailed rule not located in the checked SSC notice.	May depend on user-department duties and appointment rules.	Rule Not Located	Seek written clarification because the work may not be purely desk-based.

Can a Colour-Blind Candidate Become an Income Tax Inspector?

Evidence position Lower documented risk, not a guaranteed medical clearance

Why this post is often considered first

Inspector of Income Tax under CBDT appears in the current CGL post list but is not included in the special physical and medical posts at Paragraph 15.7. The checked SSC notice also does not state a specific colour-blindness rejection rule for this post.

This absence is useful evidence for preference planning, but it is not a universal fitness certificate. Appointment can still depend on general medical fitness and any applicable CBDT instruction.

Do not confuse two different Inspector posts Income Tax Inspector belongs to CBDT. Inspector Central Excise, Examiner and Preventive Officer belong to CBIC and are specifically included in the Annexure XV physical-standard group. Advice about one post should not be copied to the other.

The safest wording is: Income Tax Inspector is potentially safer for preference planning based on the checked SSC notice, but final medical suitability must be confirmed by the appointing department.

Assistant Section Officer and Other Desk-Oriented Posts

Many candidates with colour-vision deficiency start their research with ASO, Auditor, Accountant, Tax Assistant, Assistant, UDC/SSA outside BRO and similar office posts. Their normal work may involve files, drafting, accounts, data, computer systems, correspondence and public dealing rather than signal-colour identification.

That practical work profile can make them more comfortable options, but the phrase “desk post” does not cancel general medical fitness. Ministries can have different establishments, transfers, duties and service conditions. A candidate should therefore verify the exact department received through allotment.

Useful preference wording “Potentially safer for preference planning based on the checked SSC notice, but not an official medical guarantee.”

Why CBI, NIA and NCB Answers Conflict Online

These three posts have written visual-acuity standards. The problem starts when an answer treats “with or without glasses” as proof about colour vision. Glasses and colour perception are separate issues.

CBI SI

What is clearly written

Male height 165 cm, female height 150 cm, male chest 76 cm with expansion, distant vision 6/6 and 6/9, and near vision 0.6 and 0.8, with or without glasses.

What is not clearly written: A direct colour-blindness acceptance or rejection sentence in that subsection.

NIA SI

Why the risk profile differs

NIA uses male height of 170 cm and female height of 150 cm, with the same stated acuity values. Its duties and appointing department are different from CBI even though the vision figures look similar.

Verification action: Ask for the current NIA medical or appointment rule.

NCB SI or JIO

Why departmental confirmation matters

NCB states male height 165 cm, female height 152 cm and the same distant and near acuity values. The SSC section does not expressly settle every colour-vision condition.

Verification action: Do not place it above safer desk posts only because spectacles are permitted.

Colour-Vision Tests a Candidate May Encounter

An ophthalmologist may begin with a colour plate test, often associated with Ishihara-style plates. Depending on the purpose and authority, a detailed assessment may also use arrangement tests, signal-colour or lantern-style testing, or another clinical method.

• SSC does not necessarily use every listed method for every CGL post.
• A phone display can change colour, brightness and contrast, so it is not a final diagnosis.
• Memorising colour plates does not change the underlying condition and can create a serious preference risk.
• Do not hide a diagnosed condition from an authorised medical board.
• Ask a qualified ophthalmologist to record the type and severity clearly in your report.

Five-Step Verification Path Before Filling Post Preference

1

Get a proper colour-vision examination

Visit a qualified ophthalmologist instead of depending only on a website, app or coaching test.

2

Ask for a clear written report

Request the type, severity, visual acuity and any other relevant finding in writing.

3

Read Paragraph 15.7 and the annexures

Mark every preferred post that appears in Annexure XV or XVI and separate BRO immediately.

4

Check the user department

Search its recruitment rules, medical manual, official clarification, grievance portal or RTI response where an accessible written rule is not available.

5

Keep practical backups above uncertain posts

When written confirmation is missing, place lower documented-risk posts strategically instead of depending on a hopeful social-media answer.

Private report limitation A private ophthalmologist's report helps you understand your condition and plan preferences. It does not bind the government medical board that examines fitness under the applicable service rule.

Four Practical Post-Preference Models

Example 1: Mild red-green deficiency, Income Tax Inspector and ASO

Both are outside the checked Paragraph 15.7 special-post list. The candidate may keep them as strong practical preferences while still checking CBDT and the chosen ASO department. This is an illustration, not an appointment guarantee.

Example 2: CBI SI is the dream post, but no clear colour-vision sentence is found

The candidate should not convert the 6/6 and glasses rule into automatic colour-vision approval. A safer approach is written confirmation plus strong desk-post backups above or close to CBI. Final rules and the medical board remain decisive.

Example 3: Confirmed colour blindness and a BRO-linked preference

BRO is different because the checked annexure expressly lists colour blindness under permanent rejection. Keeping this post high would create a documented risk. This example follows the checked notice; a later notice must be read again.

Example 4: An uncertain field post is placed above safer office posts

If the candidate receives the field post and later fails its user-department medical test, SSC warns that another post may not be allotted. The safer model is to solve uncertainty before locking the order, not after allotment.

Myth Versus Verified Position

Myth

6/6 eyesight means normal colour vision.

Verified Position

Visual acuity and colour vision measure different functions.

Myth

Wearing glasses fixes colour blindness.

Verified Position

Ordinary prescription spectacles correct refractive error; they do not prove normal colour perception.

Myth

No physical test means no medical examination.

Verified Position

General or departmental medical fitness can still apply after selection.

Myth

All Inspector posts follow one rule.

Verified Position

Income Tax Inspector, CBIC Inspector, CBI SI, NIA SI and NCB SI belong to different departments and duty systems.

Myth

If one post rejects me, SSC will give the next preference.

Verified Position

The notice warns that failure in post-specific requirements may end candidature without another allotment.

Myth

An old coaching chart is enough.

Verified Position

The current SSC notification and applicable user-department rule are the primary evidence.

How to Read the Evidence Labels on This Page

Explicitly Restricted The official document clearly names colour blindness as a rejection condition for that framework.

Not Expressly Restricted The condition was not located in the checked SSC section. This does not automatically mean guaranteed eligibility.

Lower Documented Risk The post is outside the special annexure list or no specific colour-vision restriction was found in the checked notice.

Final Eligibility The authorised user department and its medical board apply the final rule for appointment.

Candidate Decision Checklist

I know the type of my colour-vision deficiency.

I have a recent ophthalmologist report.

I checked whether my preferred post appears in Annexure XV or XVI.

I checked whether colour blindness is expressly mentioned.

I did not confuse visual acuity with colour vision.

I did not assume that glasses solve colour blindness.

I checked the concerned department's rule.

I understand that SSC may not allot another post after medical rejection.

I kept lower-risk backup preferences.

I saved copies of official clarifications or rules.

Final Preference Recommendation

A colour-blind candidate should not remove every SSC CGL post from consideration. At the same time, no candidate should treat every post as automatically safe merely because the written examination is common.

Give the highest confidence to rules that are clearly written. Treat BRO as explicitly high risk while the current notice continues to list colour blindness as a permanent rejection ground. Treat CBI, NIA, NCB, CBIC and CBN carefully when colour-vision wording is not clearly stated. Keep lower documented-risk desk, audit, accounts, administrative and data posts as practical preferences after checking their departments.

When an uncertain field post is important to you, obtain written departmental confirmation before placing it above safer alternatives. A good preference list is based on evidence, not popularity.

FAQs on SSC CGL Colour Blindness Eligibility

Is colour blindness a disqualification for every SSC CGL post?

No. The checked SSC notice does not list one common colour-vision rule for every CGL post. Eligibility depends on the exact post, user department, applicable medical rule and authorised medical board.

Which SSC CGL post explicitly mentions colour blindness in the current notice?

In the checked SSC CGL 2026 notice, Annexure XVI for BRO and GREF lists cases of colour blindness under grounds for permanent rejection. This restriction should not automatically be extended to every other CGL post.

Can a colour-blind candidate become an Income Tax Inspector?

Income Tax Inspector is outside the checked Paragraph 15.7 special physical and medical post list, and no specific colour-blindness restriction was located for it in the SSC notice. It may be a lower documented-risk preference, but CBDT and the authorised medical authority decide final fitness.

Is colour blindness allowed for CBI, NIA or NCB Sub-Inspector posts?

The checked sections provide distant and near visual-acuity standards and say eyesight may be with or without glasses, but they do not expressly confirm every colour-vision condition. Written departmental confirmation is safer before placing these posts high.

Does 6/6 eyesight mean a candidate has normal colour vision?

No. A 6/6 result measures visual acuity or clarity of detail. Colour vision measures the ability to distinguish colours, so a person can have clear 6/6 vision and still have colour-vision deficiency.

Can glasses correct colour blindness for an SSC medical test?

Ordinary prescription glasses correct refractive error and do not prove normal colour perception. Special filters may change how colours appear for some people, but the authorised medical test and service rule decide government-job fitness.

What happens if a candidate fails a post-specific medical test after allotment?

The current SSC notice warns that candidature can be rejected and the candidate may not be considered for another post. Candidates should therefore resolve medical uncertainty before submitting the final preference order.
