The RRB Technician Medical Standard 2026 determines whether candidates are medically fit for Technician Grade-I Signal and Technician Grade-III posts. Under CEN 02/2026, candidates must meet the medical requirements prescribed for their selected post before appointment. These include A-3, B-1, B-2 and C-1 categories, each with different eyesight and physical fitness requirements. This article covers the RRB Technician Grade 1 and Grade 3 Medical Standards, eyesight criteria, spectacles limits, LASIK rules, post-wise eligibility, medical examination process and medical rejection.
What is the RRB Technician Medical Standard 2026?
The RRB Technician Medical Standard 2026 refers to the physical fitness and eyesight requirements prescribed for Technician posts under CEN 02/2026. Candidates shortlisted for Document Verification must undergo a medical examination conducted by the Railway Administration. The examination determines whether they can safely perform the duties associated with their allotted post. The prescribed medical category varies according to the technical role, department and work responsibilities. The medical examination may include:
- General physical fitness assessment
- Distant and near vision tests
- Colour vision assessment, where required
- Binocular vision test, where required
- Night and mesopic vision tests, where required
- Hearing assessment and relevant medical history
- Other medical tests prescribed by Railway authorities
Candidates must satisfy the medical standard assigned to their allotted post. Qualifying the CBT does not automatically establish medical fitness.

Why is the RRB Technician Medical Test important?
The RRB Technician Medical Test is important because Technician employees work in departments involving signalling, electrical systems, mechanical equipment, maintenance and Railway infrastructure. Some roles require employees to identify signals, inspect machinery or perform safety-related tasks. Medical fitness requirements therefore vary according to the nature of the post. Candidates must meet the prescribed standards to remain eligible for appointment.

| Operational safety | Ensures candidates can perform duties safely |
| Eyesight fitness | Checks distant vision, near vision and additional visual requirements |
| Technical duties | Determines suitability for maintenance and equipment-related work |
| Post-wise eligibility | Confirms that the candidate meets the assigned medical category |
| Physical fitness | Evaluates overall fitness for the allotted position |
| Final appointment | Medical fitness is a mandatory recruitment requirement |

What is the maximum eyesight power allowed in RRB Technician 2026?
The maximum permitted spectacle power in RRB Technician Medical Test 2026 depends on the medical category. A-3 permits spectacles up to 2 dioptres, while B-1 and B-2 permit up to 4 dioptres.

| B-2 | 4D | 6/9, 6/12 |
| C-1 | As per Railway medical rules | 6/12, 6/18 |
The maximum lens-power limit does not guarantee eligibility by itself. Candidates must satisfy all conditions associated with their allotted medical category.
Are spectacles allowed in RRB Technician Medical Test 2026?
Yes, spectacles are allowed for Technician posts under the prescribed medical categories, provided the candidate meets the required visual acuity and lens-power conditions. A-3 permits spectacles within the 2D limit, while B-1 and B-2 permit spectacles within the 4D limit. C-1 also allows vision assessment with or without glasses under its prescribed standard.
| Medical category | Spectacles eligibility |
|---|---|
| A-3 | Allowed within the 2D limit |
| B-1 | Allowed within the 4D limit |
| B-2 | Allowed within the 4D limit |
| C-1 | Allowed subject to applicable medical requirements |
Candidates wearing spectacles should check their current prescription and understand the visual requirements of their specific Technician post. Final eligibility is determined during the official medical examination.
Is LASIK surgery allowed in RRB Technician 2026?
LASIK eligibility for RRB Technician 2026 depends on the medical standard prescribed for the post. CEN 02/2026 states that candidates who have undergone LASIK or another surgical procedure to correct refractive error are not eligible for posts requiring A-3 medical fitness. For other medical categories, candidates must satisfy the applicable Railway medical conditions. Previous refractive surgery does not automatically establish eligibility for B-1, B-2 or C-1 posts.
| Medical category | LASIK eligibility |
|---|---|
| A-3 | Not eligible after surgery to correct refractive error |
| B-1 | Subject to applicable Railway medical rules |
| B-2 | Subject to applicable Railway medical rules |
| C-1 | Subject to applicable Railway medical rules |
Candidates should disclose previous LASIK, PRK or other eye surgery during the medical examination. Relevant medical records may be required for assessment.
Is colour blindness allowed in RRB Technician Medical Test?
Colour vision requirements differ according to the RRB Technician medical category. Candidates applying for A-3 and B-1 posts must qualify the prescribed Colour Vision Test. B-2 and C-1 have different listed medical requirements, and candidates should refer to the complete Railway medical rules. A colour vision deficiency does not result in the same eligibility outcome for every Technician post.
| Medical category | Colour vision requirement |
|---|---|
| A-3 | Prescribed Colour Vision Test required |
| B-1 | Prescribed Colour Vision Test required |
| B-2 | Follow applicable category-specific medical requirements |
| C-1 | Follow applicable Railway medical rules |
Candidates with concerns about colour vision should check the medical requirements before finalising their post preferences.
What do 6/6, 6/9, 6/12 and 6/18 eyesight mean?
Railway medical examinations use visual acuity measurements such as 6/6, 6/9, 6/12 and 6/18 to assess distant vision. These values indicate how clearly a person can see at a prescribed distance. A smaller denominator generally indicates better visual acuity. Candidates should understand these measurements because the minimum eyesight requirement changes according to the medical category.
| Eyesight measurement | Meaning |
|---|---|
| 6/6 | A person can see at 6 metres what a person with standard vision can see at 6 metres |
| 6/9 | A person sees at 6 metres what a person with standard vision can see at 9 metres |
| 6/12 | A person sees at 6 metres what a person with standard vision can see at 12 metres |
| 6/18 | A person sees at 6 metres what a person with standard vision can see at 18 metres |
The Snellen measurements are used for distant vision assessment. Near vision is measured separately using the prescribed Snellen near-vision standard.
What additional eyesight tests are conducted for RRB Technician?
Apart from distant and near vision, the Railway medical examination may include additional visual tests depending on the medical category. A-3 and B-1 candidates must qualify colour vision, binocular vision, night vision and mesopic vision tests. B-2 requires a binocular vision test. The exact assessment is conducted according to the applicable Railway medical rules.
| Eyesight test | Purpose |
|---|---|
| Colour Vision Test | Checks the ability to identify and distinguish colours |
| Binocular Vision Test | Assesses coordinated vision using both eyes |
| Night Vision Test | Assesses vision under low-light conditions |
| Mesopic Vision Test | Assesses vision under intermediate lighting conditions |
| Distant Vision Test | Measures visual acuity for distant objects |
| Near Vision Test | Measures the ability to see nearby text and objects |
Candidates must qualify the tests prescribed for their specific post. Practising visual exercises does not guarantee that a candidate will pass a medical vision test.
When is the RRB Technician Medical Test conducted?
The RRB Technician Medical Test 2026 is conducted during the final stages of recruitment. Candidates who qualify the Computer-Based Test and are shortlisted for Document Verification must undergo the prescribed medical examination. The Railway Administration conducts the examination, and the relevant schedule is communicated through official RRB instructions.
| Selection stage | Details |

Candidates should follow the instructions issued by their RRB and carry original documents wherever required.
What happens if a candidate fails the RRB Technician Medical Test?
Candidates who fail the prescribed medical standard may not be eligible for the post requiring that category. However, CEN 02/2026 contains specific provisions for medical fitness-based post allotment and appeals. A candidate who is unfit for a higher-preference Grade-III post may still be considered for a lower-preference post within the same pay level if medically fit, subject to merit, eligibility and vacancy availability. A medical appeal may be available under the prescribed conditions.
| Situation | Possible outcome |
|---|---|
| Candidate meets the required medical standard | Eligible for allotment, subject to other conditions |
| Candidate is unfit for a higher-preference Grade-III post | May be considered for another medically suitable preferred post in the same pay level |
| Candidate cannot be allotted any post in the pay level solely due to medical fitness | May receive one opportunity to submit a remedial medical appeal |
| Medical appeal is permitted | Candidate must follow the prescribed deadline, charges and procedure |
| Candidate receives a post allotment | No further medical appeal for another category within that pay level |
| Medical appeal outcome is issued | The accepted appeal examination outcome is final and binding |
Candidates should carefully review the medical fitness and appeal provisions of CEN 02/2026 before assuming that medical rejection automatically ends every possibility of appointment.
How can candidates prepare for RRB Technician Medical Test 2026?
Candidates should check the medical requirements of their preferred Technician posts before attending the medical examination. An independent medical check-up can help identify possible concerns, but it cannot replace the official Railway Medical Examination. Candidates should focus on understanding their prescribed medical category and ensuring that all required documents are ready. Candidates can follow these steps:
- Check the medical standard assigned to the selected Technician post.
- Review the distant vision and near vision requirements.
- Verify the permitted spectacle-power limit.
- Check the LASIK restrictions applicable to the post.
- Understand the prescribed colour vision and binocular vision tests.
- Keep relevant medical records and prescriptions available.
- Follow the Document Verification and Medical Examination schedule.
- Read the official CEN 02/2026 medical instructions carefully.
