to a final decision.

5. The candidate will also be weighed and his weight recorded in kilograms; fractions of half a kilogram should not be noted.

6. (a) The candidate’s eye-sight will be tested in accordance with the following

rules. The result of each test will be recorded.

(i) General- The candidate’s eyes will be submitted to a general

examination directed to the detection of any disease or abnormality. The candidate will be rejected if he suffers from any morbid conditions of eye, eyelids or contiguous structure of such a sort as to render or are likely at future date to render him unfit for service.

(ii) Visual Acuity- The examination for determining the acuteness of

visions includes two tests-one for distant the other for near vision. Each eye will be examined separately.

(b) There shall be no limit for maximum naked eye vision but the naked eye

vision of the candidates shall however be recorded by the Medical Board or other medical authority in every case, as it will furnish the basic information in regard to the condition of the eye.

(c) The following standards are prescribed for distant and near vision with or without glasses for different types of services.

(d) (i) in respect of the Technical service mentioned above any other service concerned with the safety of public the total amount of Myopia (including the cylinder) shall not exceed minus 4.00 D. Total amount of hypermetropia (including the cylinder ) shall not exceed plus 4.00 D:

Provided that in case a candidate in respect of the services classified as “Technical” (other than the Services under the Ministry of Railways ) is found unfit on grounds of high myopia the matter shall be referred to a special board of three ophthalmologists to declare whether this myopia is pathological or not. In case it is not pathological, the candidate shall be declared fit, provided he fulfils the visual requirements otherwise.

(ii) In every case of myopia, fundus examination should be carried out and the results recorded. In the event of pathological condition being present which is likely to be progressive and affect the efficiency of the candidate, he/she should be declared unfit.

(e) Field of vision: The field of vision shall be tested in respect of all services by the confrontation method. When such test gives unsatisfactory or doubtful result the field of vision should be determined on the perimeter.

(f) Night Blindness: Broadly there are two types of night blindness (1) as a result of Vitamin A deficiency and (2) as a result of Organic disease of Retina-common cause being Retinitis Pigmentosa. In (1) the fundus is normal, generally seen in younger age group and ill nourished persons and improves by large doses of Vitamin A. In (2) the fundus is often involved and mere fundus examination will reveal the condition in majority of cases. The patient in this category is an adult and may not suffer from malnutrition persons seeking employment for higher posts in the Government will fall in this category. For both (1) and (2) dark adaptation test will reveal the condition. For (2) specially when fundus is not involved electro-Retinography is required to be done. Both these tests (dark adaptation and retinography) are time-consuming and require as a routine test in a medical check up. Because of these specialized set up, and equipment and thus are not possible as a technical considerations, it is for the Ministry/Department to indicate if these tests for night blindness are required to be done. This will depend upon the job requirement and nature of duties to be performed by the prospective Government employees.

For Railway Services (IRTS, IRAS, IRPS and RPF) - Night blindness need not be tested as a routine but only in special cases. No standard test for the testing of night blindness or dark adaption is prescribed. The Medical Board should be given the discretion to improvise such rough test e.g., recording of visual acuity with reduced illumination or by making or by making the candidate recognize various objects in a darkened room after he has been there for 20 to 30 minutes. “Candidates” own statements should not always be relied upon but they should be given due consideration.

(g) Colour Vision: The testing of color vision shall be essential in respect of the Technical Services mentioned above. As regards the non-Technical Services/posts the Ministry/ Department concerned will have to inform the medical board that the candidate is for a service requiring colour vision examination or not.

For the IPS and other Police Services, Group ‘A’ and ‘B’ Indian Railway Traffic Service Group A posts in the Railway Protection force and for other Services concerned with the safety of the public higher grade of colour vision is essential but for others lower, grade of colour vision should be considered sufficient.

Satisfactory colour vision constitutes, recognition with ease and without hesitation of signal red, green and yellow colours. The use of Ishihara’s plates, shown in good light and a suitable Edrige Green’s lantern shall be considered quite dependable for testing colour vision. While either of the two tests may ordinarily be considered sufficient in respect of services concerned with road, rail and air traffic, it is essential to carry out the lantern test. In doubtful cases where a candidate fails to qualify when tested by only one of the two tests, both the tests should be employed. However both the Ishihara’s plates and Edrige Green’s lantern shall be used for testing colour vision of candidates for appointment to the Indian Railway Traffic Service and Group ‘A’ posts in the Railway protection Force.

(h) Ocular condition other than visual acuity-

(i) Any organic disease or a progressive refractive error, which is likely to result in lowering visual acuity, should be considered a disqualification. (ii) squint: For technical services where the presence of binocular vision is essential squint, even if the vision acuity in each eye is of prescribed standard should be considered a disqualification. For other services the presence of squint should not be considered as a disqualification if the visual acuity is of the prescribed standards. For Railways technical services binocular vision is essential.

(iii) if a person has one eye or if he has one eye which has normal vision and the other eye is amblyopic or has subnormal vision the usual effect is

that the person is lacking stereoscopic vision for perception of depth. Such vision is not necessary for many civil posts. The medical board may recommend as fit such persons provided the normal eye has-

(i) 6/6 distant vision j/I near vision with or without glasses provided the error in any meridian is not more than 4 dioptres for distant vision.

(ii) Has full field of vision.

(iii) Normal colour vision wherever required:

Provided the Board is satisfied that the candidate can perform all the functions for the particular job in question.

The above relaxed standard of visual acuity will NOT apply to candidates for post/services classified as “TECHNICAL” The Ministry/Department concerned will have to inform the medical board that the candidate is for a “TECHNICAL” post or not.

(iv) Contact Lenses: During the medical examination of

Candidate, the use of contact lenses is not to be allowed. It is necessary that when conducting eye test the illumination of the typed letters for distant vision should have an illumination of 15 foot- candles.
