What is low vision?
Low vision means that even with regular glasses, contact
lenses, medicine, or surgery, people find everyday tasks difficult
to do. Reading the mail, shopping, cooking, seeing the TV,
and writing can seem challenging.
Millions of Americans lose some of their vision every year.
Irreversible vision loss is most common among people over
age 65.
Is losing vision just part of getting older?
No. Some normal changes in our eyes and vision occur as we
get older. However, these changes usually don't lead to low
vision.
Most people develop low vision because of eye diseases and
health conditions like macular degeneration, cataract, glaucoma,
and diabetes. A few people develop vision loss after eye injuries
or from birth defects. While vision that's lost usually cannot
be restored, many people can make the most of the vision they
have.
Your eye care professional can tell the difference between
normal changes in the aging eye and those caused by eye diseases.
How do I know if I have low vision?
There are many signs that can signal vision loss. For example,
even with your regular glasses, do you have difficulty:
- Recognizing faces of friends and relatives?
- Doing things that require you to see well up close, like
reading, cooking, sewing, or fixing things around the house?
- Picking out and matching the color of your clothes?
- Doing things at work or home because lights seem dimmer
than they used to?
- Reading street and bus signs or the names of stores?
How do I know when to get an eye exam?
Regular dilated eye exams should be part of your routine
health care. However, if you believe your vision has recently
changed, you should see your eye care professional as soon
as possible.
