Eyesight Requirements for Government Jobs in India (2026): Complete Category-Wise Guide
Eyesight is one of the most common reasons candidates are declared medically unfit for government jobs — and one of the most misunderstood. This guide breaks down the exact visual acuity, glasses, LASIK and colour blindness rules for SSC, defence, police, railways, UPSC, PSUs, banking and driving licences, plus what all the jargon (6/6, N6, CP-I) actually means.
Quick Answer
Eyesight requirements for government jobs in India vary sharply by role. Desk-based jobs (banking, SSC clerical, UPSC non-technical services) generally accept corrected vision with glasses, contacts or LASIK and have no strict unaided cutoff. Safety-critical roles — defence, police, and railway loco pilots — require much stricter unaided vision, commonly 6/6 or 6/9, with tight limits on refractive error, and often disqualify colour blindness, squint and night blindness. Always verify against the latest official recruitment notification, since medical standards are revised periodically.
Key Takeaways
- Vision standards range from "no strict requirement" (banking, UPSC non-technical) to "near-perfect unaided vision" (Air Force flying branch).
- Glasses and contact lenses are accepted for most jobs, but a handful of safety-critical roles restrict or disallow correction.
- LASIK/PRK is generally accepted across defence, police, banking and PSUs, usually after age 20 with 12 months of stable refraction post-surgery.
- Colour blindness disqualifies candidates from most defence, police and railway technical roles, but rarely affects desk-based positions.
- Eye exercises and nutrition support general eye health but cannot correct refractive errors for a medical test — only glasses, contacts or surgery can.
Why Does Eyesight Matter So Much for Government Job Eligibility?
Government job competition in India is intense — Lok Sabha data has cited roughly 22 crore applications against about 7.22 lakh selections between 2014 and 2020 — and medical fitness, particularly eyesight, remains one of the most common reasons otherwise-qualified candidates are rejected at the final stage.
Figures are approximate, based on publicly reported government data, and may have changed since.
Vision standards exist for genuine operational reasons: roles involving machinery, firearms, aviation or public safety need candidates who can perform reliably under pressure, at night, and over a full career, without visual limitations putting themselves or others at risk. Desk-based roles simply need functional vision for reading and screen work, so their standards are far more lenient.
What Do 6/6, N6 and CP-I Actually Mean?
Government medical notifications are full of shorthand that's rarely explained. Here's what the terms you'll actually see mean:
The metric equivalent of 20/20 vision — you can read a specific line on a Snellen chart from 6 metres away, the same line a person with normal vision reads from that distance. It means normal distance visual acuity, not exceptional vision.
The second number shows how far away a person with normal vision could read that same line. 6/9 means you need to be at 6m to read what a normal-sighted person reads from 9m — i.e., somewhat below-normal acuity. 6/60 is close to legal blindness in that eye.
These refer to the smallest print size (from a standard near-vision chart) you can read comfortably at reading distance. N6 is close to normal reading vision; higher numbers (N9, N12) indicate you need larger print to read clearly.
Colour Perception grades used mainly by defence services. CP-I means normal colour vision; CP-II and CP-III indicate increasing degrees of colour vision deficiency, tested using instruments like the Ishihara chart or Farnsworth lantern test.
The unit used to measure refractive error/lens power. A "-2.5 D myopia limit" means your short-sightedness must not exceed that power for your glasses/contacts to correct you to the required standard.

Standards change with new recruitment notifications — this table is a quick-reference starting point, not a substitute for the official notification for your specific exam year.
Eyesight Requirements by Job Category
SSC (Staff Selection Commission)
- GD, CPO and paramilitary posts follow CGL-level distant vision, with near vision of N6-N9.
- Refractive errors (myopia, hyperopia, astigmatism) are accepted if glasses correct you to the minimum standard.
- Colour blindness, squint affecting binocular vision, and night blindness typically disqualify candidates for posts requiring colour identification or night duty.
Indian Army
- Myopia up to -2.5 D and hypermetropia up to +3.5 D (with astigmatism) are generally permitted if correctable to 6/6.
- LASIK/PRK is increasingly accepted if performed after age 20 with roughly 6-12 months of stable refraction before the exam.
- Colour blindness worse than CP-III, squint, progressive retinal disease, and very high refractive errors (beyond ~±6D) are disqualifying.
Indian Navy
- Refractive limits are tighter than the Army — myopia up to -1.5 D and hypermetropia up to +1.5 D for cadets and officers.
- Submarine and pilot roles within the Navy apply even stricter, often near-unaided, standards.
- Keratoconus, retinal detachment, advanced glaucoma, squint and colour perception worse than CP-II are disqualifying.
Indian Air Force
- The flying branch essentially requires normal, unaided vision — myopia beyond -0.5 D and hypermetropia beyond +2.0 D are typically disqualifying.
- LASIK is permitted across branches under strict criteria, but flying branches scrutinise post-surgical night glare, halos and corneal stability closely.
- Keratoconus, significant lens opacity, and retinal anomalies like lattice degeneration are particularly critical for pilots due to G-force risk.
Police (State & Central Forces)
- Entry-level posts generally require unaided vision, with limited leniency (roughly -1.0 D) in one eye for mild myopia or astigmatism.
- Many forces now accept LASIK-corrected candidates after a gap of 6+ months post-surgery — but check the specific force's current rules, as this has historically been a disqualifier.
- Squint, colour blindness, night blindness, and being effectively monocular are common disqualifiers, though monocular vision may qualify under disability reservations for certain supportive roles.
RRB (Railway Recruitment Board)
- Standards scale down by category — A-1 (loco pilots) and A-2 (station masters) demand unaided 6/6-6/9 vision with normal colour and night vision.
- Lower categories (B-1, B-2, C-1, C-2) allow glasses within defined power limits, with colour/night vision requirements easing further down the list.
- LASIK is specifically disallowed for A-1, B-1 and B-2 categories — a detail many aspirants miss.
UPSC (Union Public Service Commission)
- Non-technical civil services have no minimum unaided vision or dioptre limit — functional reading/screen vision is sufficient, and even significant colour blindness is acceptable.
- Technical and uniformed services like IPS require 6/6 in the better eye and 6/9 in the worse eye, with near vision of J1/J2.
- Only very severe, uncorrectable low vision (worse than 6/60 in the better eye after correction) may cause unfitness even for non-technical roles.
PSUs (Public Sector Undertakings)
- Requirements vary by company and role; technical/field/engineering posts demand sharper vision than administrative and finance roles.
- Refractive limits are typically higher for non-technical roles (myopia up to -7.5 D) than technical ones (around -6.0 D), and loosen further for candidates over 35.
- Colour blindness is generally accepted in non-technical departments like finance, but disqualifying in most technical field roles.
Banking
- Since banking roles are desk-based, corrected vision sufficient for screen and document work is all that's required.
- High-power glasses, contact lenses, LASIK, colour blindness and even monocular vision generally don't disqualify candidates.
- Banks also employ visually impaired candidates under PwD reservations for clerical or specialist officer roles, with reasonable accommodations like assistive software.
Driving Licence (Private & Commercial)
- Private (LMV/two-wheeler) licences generally require visual acuity of at least 6/12 in the better eye, with or without glasses, plus a reasonable field of vision.
- Commercial licences (taxi, bus, truck) require good vision in both eyes, given the added responsibility for passenger and public safety, and some RTOs apply colour vision checks for signal recognition.
- Requirements can vary slightly by state RTO — carrying a recent vision test report speeds up the licensing process considerably.
Is LASIK/Laser Surgery Allowed in Government Jobs?
Broadly yes, across most sectors — but the fine print matters:
- Defence (Army, Navy, Air Force): LASIK/PRK is accepted if performed after age 20, with stable refraction for at least 12 months before the medical exam. Flying and combat branches apply tighter scrutiny for side effects like night glare, halos, or corneal instability.
- Civil and desk-based services (banking, SSC, UPSC, PSUs): Refractive surgery is permitted as long as your corrected vision meets the prescribed standard, with no specific post-surgical restrictions for non-technical roles.
- Railways (RRB): LASIK is explicitly disallowed for loco pilot and certain technical categories (A-1, B-1, B-2) — a detail that trips up many aspirants who assume LASIK is universally accepted.
- Police: Increasingly accepted with a post-surgery waiting period of 6+ months, but this varies by force and has historically been a disqualifier — always check the specific notification.
Standards are revised periodically, so confirm the current criteria against your specific recruitment notification or DoPT/defence circulars before making a surgical decision based on job eligibility.
Can You Join a Government Job With Colour Blindness?
It depends heavily on the role. Colour blindness generally disqualifies candidates from defence services, police, paramilitary forces, and railway technical/safety posts (loco pilots, guards, signal operators), since accurate colour perception is essential for signal recognition, safety indicators, and combat readiness.
On the other hand, colour blindness is typically not disqualifying for SSC clerical posts, banking, UPSC non-technical services (IAS/IFS/IRS), and PSU desk-based roles, where colour perception isn't central to job performance.
How Can You Prepare Your Eyes for a Government Job Medical Test?
Genuine steps that support eye health before your medical exam:
- Get an eye exam well ahead of your medical date to know your exact numbers and address any correctable issues in time
- Ensure your glasses or contact lens prescription is current and accurate — an outdated prescription can cost you marks on the vision test
- Practise the 20-20-20 rule and basic eye exercises to reduce fatigue-related blur on exam day, especially if you've been studying intensively on screens
- Get adequate sleep and stay hydrated in the days before your medical, since fatigue and dehydration can temporarily affect visual clarity
- Maintain a diet with adequate vitamin A, lutein and omega-3s for general eye health
An important caution: eye exercises, nutrition and "natural vision improvement" methods support general eye health but cannot correct refractive errors like myopia or hypermetropia — for a medical test, only glasses, contact lenses or refractive surgery within the eligibility timelines actually change your measured numbers. Be wary of any product or programme promising to "cure" your eye power naturally before a medical exam.
Which Jobs Require Perfect 6/6 Eyesight?
These roles demand near-perfect, largely unaided 6/6 vision because any deficit directly affects safety or split-second performance:
- Air Force flying branch (pilots, navigators)
- Naval aviation and submarine entries
- Certain Army infantry and special forces posts
- Railway technical categories like Assistant Loco Pilot (A-1)
Dr. Shuchi GuptaCataract (Phacoemulsification) · LASIK · Glaucoma · Anterior Segment Specialist
"The most common mistake we see aspirants make is assuming their eyesight is 'probably fine' and only finding out at the medical exam that it isn't — by which point it's often too late to fix in time. Get a proper eye test months before your exam, not days before. If LASIK is an option for you, the timelines matter as much as the surgery itself, since most services need 6-12 months of stability before your medical."
Frequently Asked Questions About Eyesight Requirements for Government Jobs
It varies widely by role. Desk-based jobs like banking, SSC clerical posts, and UPSC non-technical services generally accept corrected vision with glasses or contact lenses and have no strict unaided-vision cutoff. Safety-critical roles like defence, police, and railway loco pilots demand much stricter standards, often 6/6 or 6/9 unaided vision, since even a minor visual deficit can affect operational safety.
6/6 vision (the metric equivalent of 20/20 vision) means you can read a specific line on a standard Snellen eye chart from 6 metres away, the same line a person with normal vision can read from that distance. It represents normal visual acuity, not "perfect" vision in an absolute sense, and is the benchmark most government medical standards use to define full visual fitness.
Yes, for most government jobs. Glasses and contact lenses are fully accepted for desk-based roles like SSC, banking, and UPSC non-technical services, and for many police, RRB, and PSU categories within specified power limits. A small number of safety-critical categories, such as Air Force flying branch, Navy submarine or pilot roles, and RRB loco pilot posts, require better unaided vision and restrict how much correction is allowed.
Generally yes, across defence, police, railways, banking, UPSC, and PSU roles, provided the candidate is above 20 years of age with a stable refraction and typically at least 12 months between surgery and the medical exam. Some safety-critical branches, such as Air Force flying roles, apply extra scrutiny for post-surgical complications like night glare or corneal haze. Always confirm current criteria against the specific recruitment notification.
Most state and central police forces require unaided distant vision of around 6/6 in the better eye and 6/9 in the other eye for constable and sub-inspector posts, along with near vision suitable for reading and documentation. Colour blindness, squint affecting binocular vision, and night blindness are typically disqualifying, though some forces allow limited correction for higher ranks or specialist posts.
Standards vary by branch and role. The Army generally requires vision correctable to 6/6, with defined limits on myopia and hypermetropia. The Navy requires unaided vision of 6/12 correctable to 6/6, with stricter refractive limits for cadets. The Air Force has the tightest standards for flying branches, where myopia is essentially not allowed, while ground duty branches permit higher refractive errors.
Yes, but not in every role. Colour blindness is disqualifying for most defence, police, and railway technical or safety-critical posts, since accurate colour perception is needed for signal recognition and warning systems. It is generally acceptable for desk-based roles such as SSC clerical posts, banking, IAS/IFS/IRS, and PSU non-technical positions.
For a private (non-commercial) driving licence in India, applicants generally need a visual acuity of at least 6/12 in the better eye, with or without glasses, along with a reasonable field of vision. Commercial driving licences (for taxis, buses, or trucks) usually require better vision in both eyes, and regional transport authorities may apply additional colour vision checks.
Roles demanding perfect 6/6 unaided eyesight typically include the Air Force flying branch, naval aviation and submarine entries, certain infantry and special forces posts in the Army, and top railway technical categories like Assistant Loco Pilot. These are roles where any uncorrected visual deficit could directly compromise safety or split-second decision-making.
