38 C.F.R. § 4.75 Examination of visual acuity.
Title 38 - Pensions, Bonuses, and Veterans' Relief
Ratings on account of visual impairments considered for service connection are, when practicable, to be based only on examination by specialists. Such special examinations should include uncorrected and corrected central visual acuity for distance and near, with record of the refraction. Snellen's test type or its equivalent will be used. Mydriatics should be routine, except when contraindicated. Funduscopic and ophthalmological findings must be recorded. The best distant vision obtainable after best correction by glasses will be the basis of rating, except in cases of keratoconus in which contact lenses are medically required. Also, if there exists a difference of more than 4 diopters of spherical correction between the two eyes, the best possible visual acuity of the poorer eye without glasses, or with a lens of not more than 4 diopters difference from that used with the better eye will be taken as the visual acuity of the poorer eye. When such a difference exists, close attention will be given to the likelihood of congenital origin in mere refractive error. [40 FR 42537, Sept. 15, 1975]
