What does a 7.5 diopter mean?

A "bad" vision score typically means vision worse than 20/20, with categories like 20/70 (moderate low vision) or 20/200 (severe low vision/legally blind in the U.S.), indicating you need to be closer to see what a person with normal vision sees at a distance, or have vision that can't be significantly improved with glasses. The larger the second number (e.g., 20/100 vs. 20/40), the poorer the visual acuity.

You can try to memorize a DMV eye chart, but it's difficult because many DMVs use randomized, digital charts or different versions (like Snellen, Sloan, or numbers) to prevent memorization, often including peripheral vision tests, so it's unreliable and potentially dangerous, with an optometrist visit being the best way to ensure you meet vision standards safely.
 

Are online eye tests accurate?

Online eye exams can offer a quick check for updating a basic prescription for some healthy adults (18-40) but are not accurate or comprehensive enough to replace professional eye exams, as they can't detect serious eye diseases (like glaucoma, cataracts) or underlying health issues, and may provide inaccurate prescriptions, especially for contacts or complex vision needs. They focus primarily on visual acuity, not overall eye health, and factors like screen quality and lighting can skew results. 

What vision are you not allowed to drive?

You generally cannot drive with eyesight below the state's minimum standard, often 20/40 vision (or 20/70 in one eye if the other is better) with corrective lenses, and a sufficient field of vision (around 70 degrees), plus the ability to see colors (red, green, amber). Conditions like severe glaucoma, macular degeneration, or vision that can't be corrected to these standards (often below 20/200) typically disqualify you, though some states allow restricted licenses with low vision aids and special testing.
