Low vision is a term for limited eyesight that cannot be improved through the use of glasses or contact lenses. It replaces older terms such as 'partially blind'. Here at Shreveport Eye Clinic in Shreveport, LA, our team of ophthalmologists offers to help patients maintain their eye health.
There are several definitions of low vision, depending on which authority you are using. Some definitions emphasize functional limitations, while others relate entirely to visual acuity. In order to qualify as having low vision, you need to remain impaired even while using glasses or contacts.
A common definition is to refer to anything less than 20/40 (corrected) visual acuity as low vision. This can be further broken down into categories, such as legally blind and tunnel vision. A visual field of less than 20 degrees is considered legally blind, but less severe restriction can also have serious effects on your life.
Most people with low vision are older individuals suffering from an eye disease or condition. Glaucoma, cataracts, macular degeneration, and diabetic retinopathy are common causes of visual impairment in adults over 65. These diseases tend to affect vision differently—for example, individuals with glaucoma are more likely to suffer from tunnel vision, while individuals with macular degeneration usually experience central vision loss.
It is extremely important for people who have low vision or who are at risk of developing low vision to see an eye doctor on a regular basis. Low vision cannot usually be improved, but it can often be prevented from worsening through proper eye care. If you have a condition that increases your risk but do not yet have symptoms, careful management can help you keep the sight that you have.
Most of the things that are good for the rest of your body are also good for your eyes:
