Color vision deficiency affects approximately 8% of male pilots and 0.5% of females, making it one of the most common conditions encountered during FAA medical exams. As of January 1, 2025, the FAA has transitioned to mandatory digital computer-based color vision testing, replacing the older plate-based and lantern tests. Here is what pilots need to know about the current testing requirements.

FAA-Approved Color Vision Tests (2025)
The FAA now recognizes only three approved digital computer-based tests for color vision screening. These are the only tests accepted — all prior physical tests have been retired:
- Color Assessment & Diagnosis (CAD) — a computerized test with a FAST screening version and a full definitive version
- Rabin Cone Contrast Test (RCCT) — Air Force/Army/Navy/Coast Guard Version, tests each eye separately
- Waggoner Computerized Color Vision Test (CCVT) — available on Windows, iOS, and Android
Previously accepted tests — including the Ishihara plates, Dvorine, Farnsworth Lantern (FALANT), Optec 900, Richmond HRR, Keystone Orthoscope, and all other physical plate or lantern-based tests — are no longer approved for FAA color vision screening.
Key Testing Rules
- An applicant may attempt any or all of the three approved tests at the time of exam
- There is no limit to the number of trials allowed
- If the pilot passes any one of the approved computer-based tests, no limitation, Letter of Evidence (LOE), or SODA is needed for any class
- Testing must be performed in person — virtual testing, downloaded, or printed versions are prohibited
- AMEs must have in-office access to at least one approved test or provide a referral for testing
- Color vision correcting lenses (e.g., X-Chrom, EnChroma) are not accepted by the FAA
What If You Cannot Pass Any Approved Test?
If you are unable to pass any of the three approved computer-based tests, the FAA will issue your medical certificate with a "Not valid for night flying or by color signal control" limitation (limitation #104: "Valid for day visual flight rules (VFR) only").
To have this limitation removed, you must appeal to the Federal Air Surgeon to review your case and request an upgrade. The previous pathway of obtaining a Statement of Demonstrated Ability (SODA) through an Operational Color Vision Test (OCVT) or Medical Flight Test (MFT) is no longer available for color vision deficiency. The FAA eliminated these pathways effective January 1, 2025.
One-Time Screening
An important change in the 2025 policy: color vision screening is now a one-time test. Once you pass an approved test, you do not need to be retested at future medical exams. Your AME will record the passing result and it carries forward.
Returning pilots who previously passed any FAA-approved color vision test — including the old Ishihara plates, FALANT, or any other formerly accepted test — do not need to take the new computer-based tests. Your AME will simply mark the exam as "PASS." The only exception is if you develop a medical condition or start taking medication that could affect color vision.
Who Needs the New Computer-Based Test?
- First-time applicants who have never been screened for color vision
- Pilots with a 3rd Class SODA/LOE wanting to upgrade to 1st or 2nd Class
- Pilots with a medical condition or medication that could affect color vision (per AME Guide or Letter of Authorization)
Existing SODA/LOE Holders
Pilots who hold a 1st or 2nd Class SODA or LOE from previously passing an OCVT and Color Vision MFT retain their privileges without needing the new computer test. Their existing certification remains valid with no color vision limitation. Pilots with a 3rd Class SODA/LOE who want to keep 3rd Class privileges also do not need retesting.
Documentation Requirements
AMEs must follow the manufacturer's guidelines to administer and record the test. Required documentation includes:
- Test name and all required scores recorded in Item 59 of the exam
- Computer-generated printout uploaded into AMCS as "Eyes — Color Vision Test"
Need guidance on color vision testing?
If you have color vision deficiency and need help navigating the new testing requirements or the limitation removal process, our AMEs can walk you through your options. We administer the Waggoner CCVT at our clinics and maintain referral relationships for the CAD and RCCT tests.
