Low vision is defined as acuity of 20/60 corrected in the best eye or peripheral vision of less than 20 degrees. In other words, low vision means that even with regular glasses, contact lenses, medication or eye surgery, an individual still has difficulty seeing.
Vision changes like these could be early warning signs of eye disease. The earlier the problem is diagnosed, the better the chance of getting successful treatment and maximizing the remaining vision.
It is important to visit an eye care professional regularly, allowing the doctor to diagnose any vision problems early. An eye care professional can tell the difference between normal changes in the aging eye and those caused by eye disease.
