![]() ![]() ![]() As one ages, the lens stiffens and loses the ability to accommodate (presbyopia) or add near focusing power. The young farsighted individual, who has a flatter cornea and less corneal refractive power, can compensate for problems in near vision by using the accommodation of the lens to add refractive power. The retina and macula may be affected by certain conditions that preclude good vision regardless of the status of the lens and cornea.ĭistant vision requires less bending of light rays (lower diopters of refraction) to focus on the retina than near vision, such as reading, requires. The lens has a variable refractive power (accommodation) of 1-18 diopters as a youth, but there is a progressive deterioration in accommodation so that the 50 year old pilot/controller may have less than 2 diopters of accommodation. The cornea has a refractive power of approximately 45 diopters (ability to bend light rays). ![]() The ability to focus images on the retina of the eye is determined by primarily by two components of the eye, the lens and the cornea. What determines the eye’s ability to focus images? However, controllers with visual field defects might possibly be considered for center operations on a case by case basis. Unilateral vision or visual field defects are waiverable for pilots, but typically not for controllers (see cataract article). ![]() With or without correction air traffic controllers must demonstrate 20/20 distant vision in each eye separately, 20/40 in each eye at 16 inches near vision, and 20/40 in each eye at 32 inches intermediate vision if they are 50 years of age or older. With FAA order 3930.3B ATC vision standards were made similar to airman standards. These individuals may also be required to wear glasses to provide optimum visual acuity. Pilots and controllers with cataracts whose vision does not correct to 20/20 at distant may be recertified to fly and control after having a surgical implantation of an artificial intraocular lens. These lenses are usually bifocals, progressive lenses or the half cut reading lenses (“granny glasses”). These lenses must correct distant vision to 20/20 in each eye.įarsighted (hyperopic) individuals or presbyopic individuals (those who require reading glasses as they age), are required to have corrective lenses AVAILABLE during aviation duties. Nearsighted (myopic) individuals, those who have blurring when viewing distant objects, are required to wear corrective lenses (glasses or contact lenses) at all times during aviation duties. There is no intermediate vision standard for third class certification. Third class medical certificates require 20/40 or better for near and distant vision. Pilots aged 50 and older also have an intermediate visual standard measured at 32″ of 20/40 or better in each eye separately. The standard for near visual acuity (16″) is 20/40 in each eye separately. Vision and FAA Standards What are the FAA standards for vision?įederal Aviation Regulations require that a pilot’s distant vision be 20/20 or better, with or without correction, in EACH eye separately to hold a first or second class medical certificate. ![]()
