What Is 20/20 Vision — And Does It Mean Your Eyes Are Healthy?

March 23, 2026  ·  Dr. Brandon Harnos, O.D.

Most people assume that if they have 20/20 vision, their eyes are perfectly healthy — but that's actually one of the biggest misconceptions in eye care. 20/20 simply means you can see clearly at 20 feet what a person with normal vision sees at 20 feet. It says nothing about your peripheral vision, depth perception, eye teaming, color vision, or the health of your retina, optic nerve, or eye pressure. You can have 20/20 vision and still have early glaucoma, diabetic eye disease, or a developing retinal problem — all with zero symptoms.

This is exactly why a comprehensive eye exam is about so much more than reading letters on a chart. At Harnos Optometry in New Paltz, NY, we evaluate your complete visual system using advanced imaging technology that detects conditions long before they affect your vision or show up on a standard eye chart. The goal isn't just clear vision — it's healthy vision for life.

If the last time your eyes were "checked" was a quick chart test at a school or doctor's office, it's time for a real exam. Schedule your comprehensive eye exam at Harnos Optometry in New Paltz today — because 20/20 isn't the whole story.

Ready to prioritize your eye health? Our team at Harnos Optometry in New Paltz is here for you.
