There are many conditions affecting the eyes and vision system. One of the most common 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?
Vision changes like these could be early warning signs of eye disease. Usually, the earlier your problem is diagnosed, the better the chance of successful treatment and keeping your remaining vision.
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.
Talk with your eye care professional
It's important to talk with your eye care professional about your vision problems. Even though it may be difficult, ask for help. Find out where you can get more information about services and devices that can help you.
Many people require more than one visual device. They may need magnifying lenses for close-up viewing, and telescopic lenses for seeing in the distance. Some people may need to learn how to get around their neighborhoods.
If your eye care professional says, "Nothing more can be done for your vision," ask about vision rehabilitation.
These programs offer a wide range of services, such as low vision evaluations and special training to use visual and adaptive devices. They also offer guidance for modifying your home as well as group support from others with low vision.
Investigate and learn
Be persistent. Remember that you are your best health advocate. Investigate and learn as much as you can, especially if you have been told that you may lose more vision. It is important that you ask questions about vision rehabilitation and get answers. Many resources are available to help you.
Write down questions to ask your doctor, or take a tape recorder with you.
Rehabilitation programs, devices, and technology can help you adapt to vision loss. They may help you keep doing many of the things you did before.
