Hawaii DFA Vision Test: 20/40 Standard, Optec 1000, and Restriction B Rules (2026)

Getting a Hawaii instruction permit requires passing a vision screening at your county driver licensing center. You'll need 20/40 visual acuity and a 70-degree horizontal field of vision. Glasses or contacts? No problem.

What Are Hawaii HDOT's 20/40 and 70-Degree Vision Standards for Permits?

The Hawaii Department of Transportation demands specific vision standards for all driver's license applicants. Your first stop? The vision screening at any driver licensing center.

• Visual Acuity: You need 20/40 vision or better in at least one eye. Correction is allowed, so don't panic if your vision isn't perfect. Check the official HIDOT vision standards rule for complete details.
• Peripheral Vision: A horizontal field of view of at least 70 degrees in one eye is mandatory. No exceptions.
• Testing Equipment: Most centers use a tabletop Optec 1000 machine. You'll look into a viewer, read letters, and identify side lights. Some locations might still use a traditional Snellen wall chart.
• Corrective Lens Requirement: If you need vision correction, bring those glasses or contacts. Wear them during the test to prove you can drive safely.

Hawaii's Restriction B: What It Means and When It Applies

Absolutely. Corrective lenses are perfectly acceptable for passing the vision screening. Just be prepared for a specific permit restriction.

• Restriction B Explained: Pass the test with corrective lenses, and you'll get 'Restriction B' on your permit. This means you must wear your glasses or contacts while driving.
• Serious Consequences: Driving without your prescribed lenses isn't just risky,it's a legal violation. Expect a citation, fine, and mandatory court appearance.
• At the Hilo office, eye drops used for morning redness blurred near vision temporarily. The applicant failed the eye chart that morning and returned that afternoon once the drops had cleared and passed. Avoid redness drops the morning of your vision test; they commonly blur near vision and can cost you an appointment slot.
