Pilot Vision Requirements
FAA Vision Standards for Pilots
The FAA sets specific visual acuity standards for each class of pilot medical certificate. According to the FAA Guide for Aviation Medical Examiners, First- and Second-Class certificates require distant visual acuity of 20/20 or better in each eye, with or without correction. Third-Class certificates require 20/40 or better in each eye.
Your Aviation Medical Examiner (AME) measures your distance acuity using a Snellen chart or digital equivalent at each periodic exam. If you wear glasses or contacts, you can still meet these standards, but your certificate will note that you must wear corrective lenses while flying.
All certificate classes require near visual acuity of 20/40 or better in each eye at 16 inches. According to the FAA Synopsis of Medical Standards (updated December 2022), pilots age 50 and older must also demonstrate 20/40 acuity at 32 inches to account for the intermediate distance of instrument panels.
Presbyopia (age-related loss of near focus) affects most adults by their mid-40s. Pilots who develop presbyopia need reading glasses or bifocals, which the FAA permits as long as acuity standards are met.
Pilots must demonstrate the ability to perceive colors necessary for safe flight. Color-coded signals, instrument displays, and navigation lights rely on accurate color discrimination. If you have color vision deficiency, the FAA may require additional testing before clearing you to fly.
Pilots who fail the initial color screening can take alternative tests such as the Farnsworth Lantern Test. Some may receive a limitation restricting flight to daytime only or prohibiting certain signal-light operations.
Corrective Options That Meet FAA Standards
The FAA allows corrective lenses for meeting vision standards. Pilots who wear glasses must carry a spare pair accessible in the cockpit during every flight. Contact lenses are permitted, and many pilots prefer them for the wider field of view they provide.
If you wear contacts, keep your lens solution in your flight bag and pack backup glasses in case of discomfort during a long flight. Low cabin humidity can worsen dryness, making lubricating drops a useful addition to your kit.
LASIK and other refractive surgeries are accepted by the FAA after a post-procedure stability period. Your surgeon must document that your vision has stabilized and meets the required acuity standards. You then notify your AME, who verifies the results before clearing you to return to flight duties.
Orthokeratology (overnight rigid contact lenses that reshape the cornea) is also gaining acceptance among aviation authorities. If you are considering refractive surgery, discuss the timeline with both your ophthalmologist and your AME before scheduling the procedure.
Some eye procedures temporarily disqualify you from flying. Intraocular gas bubbles used during retinal surgery pose the greatest concern. According to the AAO, these gas bubbles expand at altitude because aircraft cabins are not pressurized to sea level. Flying with an active gas bubble can cause a dangerous spike in eye pressure and risk permanent vision loss.
You must wait until the gas bubble absorbs completely before flying, even on commercial aircraft. Your retinal surgeon determines when the bubble has cleared. For most other routine eye procedures, including cataract surgery and glaucoma surgery, your surgeon can clear you to fly within a day or two if no complications arise.
Protecting Your Eyes During Flight
Cockpit and cabin air has very low humidity, which accelerates tear evaporation and worsens dry eye symptoms. According to the AAO, cabin air has 10-20% relative humidity, far below the 30-50% range that keeps eyes comfortable. Contact lens wearers feel this effect more than glasses wearers.
Use preservative-free artificial tears before and during flights. Direct air vents away from your face. If you fly long routes, consider removing contact lenses partway through the flight and switching to glasses.
UV radiation increases with altitude. Pilots who fly at higher altitudes or spend extended time near reflective surfaces (snow, water, clouds) face greater UV exposure. Wraparound sunglasses with UV-blocking lenses protect your eyes from cumulative UV damage that contributes to cataracts and other conditions over time.
Polarized lenses can reduce glare but may interfere with reading certain cockpit displays. Check compatibility with your specific aircraft instruments before choosing polarized aviation sunglasses.
Any sudden change in your vision while flying requires immediate attention. New floaters, flashes of light, a shadow across your visual field, or sudden blurriness could indicate a retinal problem or other urgent condition. Land as soon as practical and seek evaluation from an eye doctor.
Gradual changes such as increasing difficulty reading instruments, new trouble with night vision, or halos around lights should prompt a comprehensive eye exam before your next flight. Addressing these issues early protects both your medical certificate and your safety.
Questions Pilots Ask About Vision and Flying
Yes. The FAA permits corrective lenses for meeting vision standards. Many commercial and private pilots wear glasses or contacts. Your medical certificate will note the corrective lens requirement, and you must carry a spare pair in the cockpit.
The timeline depends on your healing and the FAA stability requirements. Most pilots return to flight duties within weeks to a few months after LASIK, once their AME confirms the vision has stabilized and meets acuity standards. Your surgeon and AME coordinate the clearance.
Failing the initial screening does not automatically disqualify you. The FAA offers alternative tests and may issue a certificate with operational limitations, such as restricting night flying or signal-light interpretation. Your AME can guide you through the alternative testing process.
Yes. Any eye surgery must be reported to your AME at your next medical exam, and many procedures require interim clearance before you can fly. Delaying disclosure can jeopardize your medical certificate. Notify your AME promptly after any eye procedure.
Dry eye alone does not disqualify you, but severe dry eye that impairs your visual acuity or comfort can affect your ability to meet medical standards. Managing dry eye with lubricating drops, adjusting cockpit humidity strategies, and following your eye doctor treatment plan keeps symptoms under control.
Flying with monocular vision (one eye covered) requires FAA authorization through a Statement of Demonstrated Ability. You cannot cover one eye and fly without approval. If you lose vision in one eye temporarily or permanently, work with your AME to determine your eligibility and any required adaptations.
Schedule Your Aviation Eye Exam
If you are a pilot or considering a career in aviation, schedule a comprehensive eye exam to ensure your vision meets FAA standards. Your eye doctor can evaluate your acuity, color vision, and overall eye health to help you fly safely and maintain your medical certificate.
