There are certain diseases of the eye that can give rise to a visual impairment and can affect the daily activities of the individual.
We will start with the disease affecting the macula, or MACULOPATHIES. The macula in the part of the retina that is responsible for the central vision. So any change in the macula will noticeably affect activities that we do daily since they affect the central vision.
Diseases that affect the macula are the following:
Age related macular degeneration which is a degenerative disease that affects the macula which happens to some people as they age. This destroys the central sharp vision, and fine details will be affected. Most of our daily tasks use our central vision so this becomes a problem for reading, driving, etc. If you were diagnosed with this disease, you might have been given vitamins, or you may have been injected with anti-vegf drugs like lucentis, or avastin or macugen. These drugs slow down the progress of the disease but do not restore vision to normal.
The good news is that with the advent of these new treatments, the visual solution is not relying on training for eccentric vision. There are devices that can make you read again, and hopefully get back to work, or doing the things you love to do.
Most of the time, glasses cannot correct the vision because of the macular disease, but there are several devices that can help.
First is the hand magnifier. They come in different powers, and the power will depend on your vision and your needs. They have a flexible working distance. With this device however, you should have steady hands or this could be tiring for prolonged reading.
How to use them:
Turn on the light switch. Hold on the magnifier flat on the page, and slowly raise the magnifier but don’t tilt the magnifier. Lift it until the page is magnified and clear. then move it sideways to read.
You can use this for spot reading, or reading material for a short time only. It’s very handy and you can carry it around with you.
