Interactive vision simulator — drag the slider to compare eyesight levels.
Compare 20/25 vision with 20/20 using the slider - fine details may look slightly soft at a distance.
With 20/25 vision, you see at 20 feet what someone with 20/20 sees at 25 feet.

This is very mild myopia; some people notice blur only in low light or at long distances.
A light prescription often restores crisp distance vision, but your exact diopters can vary by person.

Boundary is 20/200.
20/25 vision is near-normal. You might notice mild blur on small distant text, and glasses can sharpen details if needed - especially for driving or presentations.
20/25 on a Snellen chart means you see at 20 feet what a person with 20/20 eyesight could see at 25 feet.
20/25 is a very small step below normal. Many people function well without noticing it, but it can show up as slight softness in fine distance detail, especially in low light or when tired.
20/25 is generally within driving standards, but sharper correction can improve comfort and safety at night or in poor weather.
The most common reasons are very mild myopia or astigmatism. Temporary blur can also come from dry eyes or eye fatigue.
There is no exact one-to-one conversion between Snellen scores and glasses strength, but 20/25 often aligns with roughly -0.25 to -0.75 diopters for simple myopia.
The right prescription can usually improve distance clarity significantly.
Consider an eye exam if you notice:
A light prescription may help, especially for driving or night scenes.

20/25 is very close to normal. Many people function well, though you may notice slight blur on small distant details.
Not always. If you drive often, work with screens, or want sharper distance detail, a light prescription can help.
20/25 commonly corresponds to a very mild prescription, often around -0.25 to -0.75 diopters. Only an eye exam can confirm yours.
