Macular degeneration is one of the common age related eye diseases. There are a large number of aged people suffering from low vision caused by macular degeneration. The following will give some introduction on the causes, symptoms, and macular degeneration devices to help people maximize the remaining vision, read ahead.
If we want to learn about macular degeneration, we should know macula first. The macula is located in the center part of the retina, which is in charge of the detail vision, such as reading, knitting, driving or other daily tasks. If there is damage to macula by bleeding, a thinning of the tissue, or even a wasting away of the tissue, people will suffer from macular degeneration and can not see detailed information clearly. At the beginning, people may suffer from slight vision loss, if left untreated, finally people may suffer from blindness. Therefore, we can see it is important to have our eyes tested regularly in order to find out the eye problem and treat it in time.
One of the common causes for macular degeneration is due to age factor. When people are at their 40's or 50's, the macula will become weak, and they will have a low central vision. Another cause is the family history, which means if there are family members who have macular degeneration, the other members may also have this kind of eye disease. Besides, there are some people who have the genes which can put them under the risk for developing macular degeneration. For example, people who have high cholesterol, or high blood pressure will be more likely to develop macular degeneration. If we find we have blurred vision or part of vision loss, we should visit our eye doctor immediately to do a complete eye test.
In order to take some precautions for age related eye diseases, we can have some food rich in beta-carotene and Vitamins like lutein and zeaxanthin, however, this can not treat macular degeneration. Instead, we should use some new drugs which have a good effect in resisting against macular problem. Moreover, we can also resort to some devices for help. The aim of the devices is to maximize our remaining vision and help us to see detailed information clearly. Take the telescopic lens as an example, there is a tiny telescope on the lens, when we need to see detailed information, we can look through the telescope lens which can magnify the information, and for other works, we can just look through the prescription glass. It works just like bifocal reading glasses. There are various devices available for macular degeneration, and we can choose the most suitable one according to our eye condition and eye doctor's advice.
