Is 20/20 Vision REALLY Perfect Vision?
20/20 vision. It’s a term we have heard since we were children. But what exactly does that mean for you—our Safety Harbor Optical patient? The common perception is that 20/20 vision equals perfect eyesight . . . actually, not really. Let’s take a peek inside the phenomenon of 20/20 vision.
20/20 vision is used to express normal visual clarity or sharpness of vision measured from a distance of 20 feet. If you have 20/20 vision, you can see clearly at 20 feet what should normally be seen at that distance. However, if you have 20/100 vision, it means that you must be as close as 20 feet to see what a person with normal vision can see at 100 feet. 20/20 vision only indicates the sharpness or clarity of vision at a distance. There are other important vision skills, including peripheral awareness or side vision, eye coordination, depth perception, focusing ability and color vision that contribute to your overall visual ability, according to the American Optometric Association.
Some patients can see well at a distance, but are unable to bring nearer objects into focus. This condition can be caused by hyperopia (farsightedness) or presbyopia (loss of focusing ability). Other Safety Harbor Optical patients can see items that are close, but cannot see those far away. This may be caused by myopia (nearsightedness).
At Safety Harbor Optical, we recommend yearly wellness eye examinations. With a focus on technology and precision eye care that benefits our patients, we are pleased to offer an ultra high-definition, high-contrast advanced LED screen eye chart. With this technology, we can measure acuity to 20/12 and 20/10 vision! Safety Harbor Optical patients often comment how much easier the vision portion of the eye exam is using this LED technology.
Looking forward to seeing you in sunny Safety Harbor very soon!
