Interactive vision simulator — drag the slider to compare eyesight levels.
Use the slider to compare 20/10 vision with normal eyesight - distant details stay crisp and sharp.
With 20/10 vision, you see at 20 feet what someone with 20/20 sees at 10 feet.
This simulator is for educational purposes only and does not replace a professional eye exam.
20/10 is sharper-than-normal vision; most people do not need distance correction.
If you do need a prescription, it is usually very light (around 0.00 to -0.25 diopters), but only a professional exam can confirm your exact numbers.

Boundary is 20/200.
With 20/10 visual acuity, your distance vision is sharper than average and usually needs no correction. Regular eye exams help monitor eye health and any changes over time.
20/10 on a Snellen chart means you see at 20 feet what a person with 20/20 eyesight could see at 10 feet.
20/10 is sharper-than-average distance vision. Many people with this score notice extra crisp detail in everyday scenes. It is excellent acuity, but it does not automatically guarantee perfect eye health or comfort in every situation.
20/10 comfortably exceeds common driving vision standards. You should have no trouble reading road signs early and reacting to distance hazards. If you still feel eye strain or glare, an exam can check for astigmatism or dryness.
This level of acuity is often due to genetics and healthy optics, especially in younger adults. Some people reach 20/10 with glasses or contacts after correcting mild refractive error. Regular checkups still matter because acuity alone does not rule out other eye issues.
There is no exact one-to-one conversion between Snellen scores and glasses strength, but 20/10 often aligns with roughly -0.25 to 0.00 diopters for simple myopia.
The right prescription can usually improve distance clarity significantly.
With 20/10, distance glasses are usually not needed.
Consider an eye exam if you have:
These symptoms can relate to astigmatism, dry eye, or screen-related strain even when acuity is high.
Quick comparison to nearby levels:
| Level | Compared to 20/10 |
|---|---|
| 20/10 | Current level |
| 20/15 | More blur than 20/10 |

Yes. 20/10 vision means you can see at 20 feet what someone with normal 20/20 vision needs to be 10 feet away to see clearly. It is considered better-than-average distance vision.
Most people with 20/10 do not need distance glasses, but you could still need correction for astigmatism, eye strain, or near-vision tasks. An eye exam is the only way to know for sure.
It can. Vision may change with age, screen habits, or eye conditions. Regular checkups help catch changes early and keep your prescription up to date if needed.
