RRB A-2 Medical Fitness Standard 2026: Criteria, Eye Test and Railway Posts

Introduction

The Railway Recruitment Board (RRB) conducts recruitment for various posts in Indian Railways, and candidates must satisfy the prescribed medical fitness requirements for their selected positions. The A-2 medical standard is an important category for posts involving operational responsibilities where good eyesight and overall physical fitness are essential.

Candidates preparing for Railway examinations should understand the A-2 medical criteria before applying. These requirements include distant vision, near vision, colour vision, binocular vision, night vision and mesopic vision. The medical examination also assesses whether candidates meet the applicable physical fitness conditions.

What Is the RRB A-2 Medical Standard?

The RRB A-2 medical standard is a medical fitness category that is a prescribed condition that candidates must meet in order to apply for designated Railway jobs. It has rigorous visual acuity specifications due to the fact that some of the jobs performed require good visual acuity in various operating environments.

The candidates should not have glasses for the visual standard as it has been mentioned in the recruitment notification. They should also meet the required standards of colour vision, binocular and night and mesopic vision tests. Medical eligibility is not automatically granted due to a candidate's education, examination or document verification. Medical fitness is determined individually by the rules of each position.

Which Railway Posts Require A-2 Medical Fitness?

This is one of the most important points for Railway aspirants. According to the relevant RRB recruitment notifications, the following posts specify the A-2 medical standard:

The official Section Controller notification specifies A-2 for the Section Controller post. The NTPC Graduate notification lists A-2 for Station Master, Goods Train Manager and Traffic Assistant. Candidates can verify these classifications in the relevant official notices. (RRB, CEN 04/2025; RRB, CEN 06/2025).

Does A-2 apply to every Railway post?

No. A-2 is not a universal medical requirement for all Indian Railway jobs. Other posts may require A-1, A-3, B-1, B-2, C-1, C-2 or another category, depending on the applicable recruitment rules. For example, the NTPC Graduate notification specifies B-2 for Chief Commercial Cum Ticket Supervisor and C-2 for Junior Accounts Assistant Cum Typist and Senior Clerk Cum Typist.

Similarly, candidates should not assume that every Group D, Assistant Loco Pilot or Technician vacancy requires A-2. The medical category must be checked against the exact post and recruitment notification. If a later notification changes the classification, the latest applicable official notice takes precedence.

RRB A-2 Medical Fitness Criteria

These requirements are stated in the applicable RRB notifications, including the Section Controller recruitment notice. Candidates should refer to the complete notification for any additional conditions or post-specific instructions.

RRB A-2 Eye Test and Vision Standards

1. Distant Vision Test

The distant vision requirement is 6/9 in both eyes without glasses. The notation indicates visual acuity measured with a regular vision chart. Candidates are required to meet the prescribed standard without glasses or contact lenses.

2. Near Vision Test

Prescribed near vision is Sn 0.6 in both eyes (without glasses). This test measures near vision (seeing close objects or text). The candidate must possess the said standard at the time of medical examination.

3. Colour Vision Test

For Railway activities, it is necessary to have colour vision to be able to distinguish signals or colour-coded indications correctly. Candidates must comply with colour vision tests for A-2 medical rules.

4. Binocular Vision Test

Binocular vision assesses the binocular function. The test aids in the evaluation of visual functions needed for depth perception and coordinated vision. Medical requirements prescribed for the candidate must be fulfilled.

5. Night and Mesopic Vision Tests

Night vision and mesopic vision assessments measure how well someone can see in low-light. These tests are especially relevant in operation environments which can experience changes in lighting conditions. Candidates are required to pass the tests as prescribed for the post they are applying for.

The Section Controller notification also specifies distant vision without a fogging test. Candidates are expected to use the same terms and conditions as set out in their own notification.

Is LASIK Surgery Allowed for RRB A-2?

Those who have any refractive surgery (such as LASIK) should review the appropriate notification prior to applying. As per the cited Section Controller recruitment notice, the candidates undergoing LASIK surgery or any surgery for refractive error are not eligible for posts which demand A-2 medical fitness. An applicable notice should be read to determine the exact wording and any changes made.

Candidates must NOT use general advice or advice from another posting to assess their eligibility. In case of eye surgery, they have to read the appropriate notification and clarify with the recruiting authority if required.

General Medical Examination and Physical Fitness

Vision is an important aspect of A-2, but the general fitness requirement must be met also. Railway medical officials determine fitness by the medical rules in force and the requirements of the position.

Applicants must give correct medical details and supply pertinent medical history (if asked). They are also required to take the appropriate documentation to the recruitment authority and directions for the medical examination. If the candidate has not met the medical standard, he or she will not be appointed, even if he or she passes the computer-based test or other means of selection.

How to Prepare for the RRB A-2 Medical Test

Prior to the Medical Examination the following practical steps may be taken by the candidates:

• Get an eye exam from a qualified eye professional prior to the Railway medical exam.

• Test for near & far vision to A2 standards.

• If they are concerned about colour vision or other visual functions they should seek professional advice.

• Medical conditions and amendments are available in the recruitment notification, please refer to the official notification.

• Carry all required documents and medical records as specified by the recruiting body.

• A-2 rules will NOT allow glasses, contact lenses or previous eye surgeries.
