From CFR 14 Part 67:
The requirements for first and second class airman medical certificates are:
“(a) Distant visual acuity of 20/20 or better in each eye separately, with or without corrective lenses. If corrective lenses (spectacles or contact lenses) are necessary for 20/20 vision, the person may be eligible only on the condition that corrective lenses are worn while exercising the privileges of an airman certificate.
(b) Near vision of 20/40 or better, Snellen equivalent, at 16 inches in each eye separately, with or without corrective lenses. If age 50 or older, near vision of 20/40 or better, Snellen equivalent, at both 16 inches and 32 inches in each eye separately, with or without corrective lenses.
Less restrictive standards apply to a third class certificate.
One of the anxieties pilots experience when taking the periodical medical exam is: “Will I be required to wear glasses from now on?”
Traditionally, for a pilot who fails to meet FAR 67 standards, the options are limited to wear glasses or contact lenses while flying or go through a risky operation.
Wearing glasses is a nuisance in itself. A corrective lens for distant impairs the reading and intermediate and vice versa. The situation worsens if one needs an independent lens for all three, reading, distance and intermediate. Progressive glasses would be most appropriate for such condition.
But is there another option? I did some research and came across a holistic approach for improving Natural Vision.
Help can be obtained through specialists or audiovisual programs. Since this article does not endorse any product, I suggest for pilots, who are interested in finding such specialists or products, to conduct an Internet search using the following keywords:
“natural vision” “non surgical vision therapy” and similar terms.
