Interactive vision simulator — drag the slider to compare eyesight levels.
Drag the slider to compare 20/15 vision with 20/20 - distance details look exceptionally clear.
With 20/15 vision, you see at 20 feet what someone with 20/20 sees at 15 feet.
This simulator is for educational purposes only and does not replace a professional eye exam.
20/15 is excellent vision; distance glasses are rarely needed unless for astigmatism or eye strain.
If correction is needed, prescriptions are usually very light and close to 0.00 diopters. Only a professional exam can confirm your exact numbers.

Boundary is 20/200.
With 20/15 visual acuity, you have excellent distance vision that is slightly sharper than normal. Most people do not need distance correction, but regular eye exams are still recommended.
20/15 on a Snellen chart means you see at 20 feet what a person with 20/20 eyesight could see at 15 feet.
20/15 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.
20/15 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 20/15 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 20/15 often aligns with roughly -0.25 to 0.00 diopters for simple myopia.
The right prescription can usually improve distance clarity significantly.
With 20/15, 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.
This simulator is for education only. Screen size, viewing distance, lighting, and eye health all affect what you see. If you are worried about your vision, please schedule a professional eye exam.

20/15 vision means you can see at 20 feet what someone with 20/20 vision needs to be 15 feet away to see clearly. It indicates excellent distance sharpness.
It is better than average and often described as excellent. Many people call 20/20 normal, while 20/15 is a bit sharper than normal.
Yes. You can have astigmatism, dry eyes, or headaches even with strong acuity. Routine exams help catch problems early.
