Learn about 20/20 Vision in 2020!
What does 20/20 mean and do YOU have “perfect” vision
Visual acuity is the professional standard measurement on how well the eyes can see based on a normal level of clarity. Using this tool can gauge whether you need corrective lenses or if some disease is affecting your vision.
The term 20/20 compares what you can see at 20 feet to what a normal human can. For example: 20/100 vision means you can see an object in the distance at 20 feet, but a normal person can see the same object at 100 feet.
Is 20/20 perfect vision? Not exactly!
Some people are able to read the 20/20 line, but other parts of their vision is affected from things like:
Cataracts or astigmatism—making letters fuzzy and dull
Retinal diseases and focusing problems—some letters are missing or moving around
Double letters—trauma or eye muscle coordination
How is vision corrected?
After a vision acuity is taken in both eyes, focusing system assessed and eye movements/field are confirmed normal—glasses are prescribed for a specific distance and use. Contact lenses and corrective eye surgery are also a great options for patients that want to be glasses free and see clearly.
