As someone who has always dreamed of flying, I was disheartened when my optometrist diagnosed me with astigmatism during a routine eye exam. At that moment, I thought my dreams of becoming a pilot may have been shattered. After doing some research however, and speaking with professionals in the industry, I quickly learned that having astigmatism does not mean that the doors have closed on the pursuit of my lifelong dream.

Being diagnosed with astigmatism does not automatically disqualify you from exercising the privileges of a pilot license. Working with your Aviation Medical Examiner (AME), you may be cleared to fly if you can demonstrate 20/40 vision or better through any approved corrective measure.

In response, I have created this comprehensive resource guide, in which we will:

  • take a closer look at the impact of astigmatism on individuals aspiring to become pilots.
  • discuss how pilots with astigmatism navigate their aviation journey, both in terms of general aviation as well as as commercially.
  • explore the vision requirements set by the Federal Aviation Administration (FAA).
  • examine the various options available for correcting astigmatism, including eyeglasses, contact lenses, and refractive surgery.

Ultimately, the ability to pursue a pilot license with astigmatism will depend on various factors, including the severity of the condition, the type of flying you plan to do, and the assessment criteria set by the FAA.

What You Need To Know:

  • Astigmatism doesn’t automatically disqualify you from becoming a pilot.
  • A determined mindset and proactive management of the condition can help aspiring pilots, as well as existing pilots, succeed in their aviation journey.
  • Astigmatism is a common eye condition that affects the way light is processed by the retina.
  • Pilots must meet specific vision requirements set forth by the FAA in order to be cleared to fly.
  • Options for correcting astigmatism include eyeglasses, contact lenses, and refractive surgery.

Understanding Astigmatism: What Is It Exactly?

As a person who has astigmatism, I know firsthand how challenging it can be to explain this eye condition to others. Simply put, astigmatism is a common refractive error that affects the way light enters the eye, causing blurry or distorted vision.

More specifically, astigmatism occurs when the cornea or lens is not completely round, but rather has a more oblong shape. This causes light to focus on two points on the retina, rather than a single point, resulting in blurred or distorted vision.

Aside from blurry vision, other common symptoms of astigmatism include eye strain, headaches, and difficulty seeing at night. 

Common Symptoms of Astigmatism

So, how do you know if you have astigmatism? A comprehensive eye exam with your optometrist or ophthalmologist can diagnose astigmatism, as well as determine the degree and type of astigmatism you have.

According to Mayo Clinic, common symptoms of astigmatism include:

  • Blurred or distorted vision, both up close and at a distance
  • Eyestrain
  • Headaches
  • Squinting
  • Difficulty seeing at night

It’s important to note that astigmatism can occur alongside other refractive errors, such as nearsightedness or farsightedness.

Simply put, astigmatism is a refractive error that occurs when the cornea (the clear outer layer of the eye) or the lens inside the eye has an irregular and asymmetrical shape. This causes light to focus unevenly on the retina, resulting in blurry or distorted vision.

The severity of astigmatism can vary from person to person, and some individuals may not even realize they have the condition. However, if left uncorrected, astigmatism can impact your daily activities, including your ability to drive, read, use a computer… and of course, pilot an aircraft!

Types of Astigmatism

There are two main types of astigmatism: regular and irregular.

Regular Astigmatism

Regular astigmatism occurs when the cornea has an oblong shape.

Irregular Astigmatism

Irregular astigmatism can be caused by eye injuries, surgeries, or other conditions like keratoconus.

How Do You Measure Astigmatism?

The degree of astigmatism is measured in diopters.

A diopter is a unit used to calculate the focusing strength of a pair of glasses or contact lenses. This measurement helps your eye doctor determine the right treatment for your astigmatism.

Severity of AstigmatismDiopters
Mild0.5 to 1.0 diopter
Moderate1.0 to 2.0 diopters
Severe2.0 diopters or more

Vision Requirements Based On Class of Pilot Certification

The FAA has published a concise synopsis of the medical standards that serve as the basis for the minimum vision requirements for vision. It further expounds upon what exactly you can and you cannot do as a pilot, depending on the type of flying you wish to perform, and the associated circumstances therein.

Levels of Vision

There are 4 different levels of vision, as far as the FAA is concerned:

  • distant vision
  • near vision
  • intermediate vision
  • color vision

FAA’s Medical Certification Process

Before obtaining a certification, pilots have to go through a medical examination process with an FAA-designated aerospace medical examiner (AME). During this process, the examiner will evaluate your overall health and assess your vision, including possible astigmatism.

The FAA recognizes various vision correction methods, such as contact lenses, glasses, and refractive surgery, as long as they meet the FAA’s visual acuity standards. Pilots also need to pass regular vision exams to maintain their certification.

The FAA issues 4 different classes of medical certification to pilots: 

Medical CertificatePilot LicenseType of Aviation OperationsFederal Aviation Regulations (FAR)
1st ClassAirline Transport PilotPassenger & cargo airlinesPart 67.103
2nd ClassCommercial Pilot LicenseAny commercial operation other than major airline or cargo servicesPart 67.203
3rd ClassPrivate Pilot LicenseGeneral aviation (non-commercial) flightsPart 67.303
Basic MedPrivate Pilot LicenseGeneral aviation – with limitationsPart 68.5
FAA Vision Requirements As Per Federation Aviation Regulations

FAA Vision Requirements Cheat Sheet

Generally speaking, to meet the visual acuity requirements:

  • you must have 20/20 or better vision for commercial aviation, with or without corrective lenses.
  • you must have 20/40 or better vision for general aviation operations, with or without corrective lenses.

Visual Acuity Testing

The Federal Aviation Administration (FAA) has well-defined vision requirements for pilots to ensure that they can adequately perceive their surroundings, navigate, and anticipate any potential safety risks. If you have astigmatism, you may require corrective lenses to achieve the required visual acuity standards. Contact lenses or eyeglasses can help enhance your visual acuity and may be required to satisfy these requirements.

The visual acuity test measures how clearly you can see letters on an eye chart from a distance of 20 feet. If you use corrective lenses such as eyeglasses or contact lenses, the lenses shouldn’t exceed a certain prescription limit.

The test assesses your ability to see colors, shades, and contrast and detects any issues with your eye muscles, binocular vision, and peripheral vision. Medical conditions that can affect your vision, such as astigmatism, may disqualify you from obtaining a pilot certification in some cases.

pilot requirements

The FAA has published a detailed Guide For Aviation Medical Examiners on what type of vision tests to perform and how to perform them, on pilots. Furthermore, it also expounds on the assessment criteria, which the pilot must meet, in order to be successfully issued a medical certificate.

Tangential Issues Indirectly Impacted By Visual Acuity

It’s important to note that visual acuity is not the only factor aviation authorities consider. They also evaluate your ability to maintain situational awareness, judge distances, and withstand gravitational forces during flying. However, meeting the visual acuity requirements is a crucial step to becoming a pilot.

Flying with Astigmatism: Corrective Lenses

As a pilot, having clear vision is essential to safely operate an aircraft. When it comes to astigmatism, there are several corrective measures available to ensure that pilots can meet the necessary vision standards. Let’s take a look at some of the options:


Glasses are a go-to choice for pilots with astigmatism. They can be designed to correct astigmatism and other vision problems at the same time. One disadvantage of glasses is that they can easily fall off or become uncomfortable during longer flights, especially if you are wearing bulky headphones. It’s important for pilots to select glasses that fit securely and comfortably.

Contact Lenses

Astigmatism-correcting contact lenses are another common vision corrective measure for pilots with astigmatism. They provide a wider field of view compared to glasses and eliminate the potential discomfort caused by wearing glasses for extended periods. However, they can be more challenging to maintain and have a higher risk of complications such as dry eyes.

Standard contact lenses are spherical in shape.

Toric lenses, are a special type of contact lens, which are specifically shaped to correct astigmatism.

Your optometrist will most likely prescribe you toric lenses, if you are diagnosed with astigmatism.

When choosing between eyeglasses and contact lenses, pilots should consider the type of flying they do, their individual needs and preferences, and any potential comfort or vision issues. Some pilots may prefer wearing glasses for ease of use, while others may opt for contact lenses that provide a wider field of vision and better peripheral awareness.

Pilots Should Always Keep Spare Lenses In Their Flight Bag

It is important to note that pilots with contact lenses should always have backup eyeglasses available in their flight bag.

You never know when a contact lens could:

  • become dislodged
  • shifted off of your iris
  • start irritating you
  • becoming dry, leading to blurred vision

This should also be true for pilots with glasses. Although rare, you never know when you might lose your current pair of glasses in flight. A screw could come loose, a lens could pop-out. It pays to have a spare set of glasses in your flight bag!

Refractive Surgery for Pilots with Astigmatism

In some cases, pilots with astigmatism may choose to undergo LASIK or other surgical procedures to correct their vision. While these procedures can provide significant benefits, there are also some potential risks to consider, such as dry eyes and halos. It’s important to thoroughly do your due diligence and research, and consult with a qualified medical professional to determine if this the right option for you, before deciding on surgery.

If you have astigmatism and are considering pursuing a career as a pilot, refractive surgery may be an option worth exploring. Refractive surgery is a type of eye surgery that corrects vision problems, such as nearsightedness, farsightedness, and astigmatism, by reshaping the cornea.

The table below summarizes the different types of refractive surgery available:

Type of SurgeryDescriptionProsCons
LASIKUses a laser to create a thin flap in the cornea and reshape the underlying tissue to correct visionFast recovery time, little to no pain, high success rate, permanent correctionPossible side effects, such as dry eyes, glare, halos, and undercorrection or overcorrection
PRKUses a laser to remove the thin outer layer of the cornea and reshape the underlying tissue to correct visionNo flap created, no risk of flap complications, permanent correctionLonger recovery time, discomfort during healing, possible side effects similar to LASIK
SMILEUses a laser to create a small incision in the cornea and remove a piece of tissue to reshape the cornea and correct visionLess invasive than LASIK and PRK, faster healing time, fewer side effectsNot as widely available, potential for undercorrection or overcorrection
Summary of different types of refractive surgery, and their respective pros and cons.

Before considering refractive surgery, it is important to weigh the potential benefits and drawbacks, as well as discuss the procedure with your ophthalmologist and your aviation medical examiner. The FAA has specific guidelines and restrictions for pilots who have undergone refractive surgery, so it is important to be well-informed before making a decision.

The FAA has published an information pamphlet, to serve as general guidance for pilots, to help them determine whether you qualify for LASIK, and whether LASIK is right for you.

Remember: Refractive surgery is a personal decision that should be made after careful consideration and consultation with medical professionals. It is not a requirement for pursuing a career as a pilot, but it may provide a viable option for those with astigmatism who want to achieve optimal visual acuity.

Frequency of Eye Exams

Regardless of the chosen method, it’s important for pilots with astigmatism to undergo regular eye exams to ensure their vision correction is up to par for safe flying.

By law, the FAA requires all pilots to renew their medical certificate at set intervals, depending on the class of the certificate, and the age of the pilot.

This involves undergoing a comprehensive medical exam, administered by an AME.

The medical exam must include a vision test.

Bear in mind what while the above table depicts the minimum legal requirements, it would behoove you, as a pilot diagnosed with astigmatism, to consider seeing an optometrist more frequently, as needed, in order to keep up with and address any potential changes in your vision.

Visual Conditions That Can Aggravate Astigmatism

As a pilot, one of my top priorities is ensuring the safety of myself and my passengers. Astigmatism can pose unique challenges to pilots, but with proper management, flying with this condition can be absolutely safe.

While we delved into the various corrective measures for astigmatism in the sections above, it is important to note that the aim is not only to be able to achieve 20/40 or 20/20 vision, but to also be able to address any situations that could pose a challenge to and further aggravate your astigmatism.

Whether you are flying during the day or you are flying at night, you may find it necessary to make adjustments to the lighting within the cockpit, to reduce eye strain.

During the daytime, that may involve using the windshield visor or the wearing of sunglasses, to reduce glare due to excessive ambient brightness glare that can cause eye strain.

At night, this may involve reducing the brightness and intensity of cockpit lighting, which is crucial for being able to adequately and accurately scan the instrument panel.

This also can tangentially impact your peripheral vision as well.
