Acuity standard in Connecticut
The Connecticut CT DMV requires a corrected or uncorrected visual acuity of at least 20/40 in at least one eye to issue an unrestricted license. Acuity is measured with a Snellen chart at the counter; you read lines until you miss too many letters. If you wear glasses or contacts, bring them — your prescription is what determines whether you pass.
Peripheral vision and color vision
Connecticut also screens for peripheral vision (your ability to see motion to the side without turning your head) and color vision (your ability to distinguish red, yellow and green traffic signals). A failure in either typically results in a restricted license rather than a full denial — for example, a daylight-only restriction or a no-freeway restriction.

What if you fail the screen
If you fail the counter vision screen, the CT DMV will ask you to obtain a Vision Specialist Report from an eye doctor and bring the completed form back. The report covers acuity, peripheral field, and ocular health. With a satisfactory report and an updated prescription, the CT DMV typically issues the license with a "corrective lenses" restriction printed on the back.
Age-based re-testing
In many Connecticut counties, drivers age 70 and older must complete the vision screen in person at every renewal — even when other drivers can renew online or by mail. The same standard (20/40 acuity in at least one eye, corrected or uncorrected) applies, but the in-person requirement catches age-related vision changes that the driver may not have noticed.
Tips for the day of the test
Bring the glasses or contacts you actually drive with — not last year's pair. If you have any chance of failing the screen, schedule an eye-doctor visit before your CT DMV appointment so you can bring an up-to-date prescription. Avoid testing late in the afternoon if your eyes fatigue easily; first appointment of the day usually produces the best result.
