What are the basic cause of poor eye sight due to old age? Are there effective treatments for this?

Answer 1

The shape of your retina changes as you age, which is why you see so many elderly people with glasses. It's normal to become
more nearsighted but the elderly also have the extra problem of reading things up close as well. So, many will have to get bi-focals for distance and for close up reading. Another reason is elderly people usually don't eat a completely healthy diet so they aren't getting all the important vitamins and minerals that can keep the eyes healthy. Vitamin A, for example and beta carotene (from orange fruits and vegetables) help keep the eyes working.
Another reason is cateracts. Surgery is really the only way to see when cateracts are present. As far as taking care of the other causes, eat a well balanced diet and take a supplement daily.
Now, I don't know if this would work for you but it has for me. I have a theory. I think that when a person starts wearing glasses all the time, they need to get stronger ones every year because your eyes become dependent on them. I wear glasses only when watching T.V. I refuse to wear them all the time. I force my eyes to focus on objects and I can feel a little strain behind my eyes, which tells me I'm doing it correctly. I've been doing this for several years. I went to get some new glasses a year ago and the optomitrist says, "How unusual. You actually need a milder prescription than the one you had four years ago." My eyes had gotten better, not worse. I also used to notice blurriness when reading close up but have forced my eyes to focus. Much of that has gone away. I don't know if what I'm doing will last for years and years, eventually I may have to give in and get bi-focals and wear glasses all the time. But why rush things? So, you might look on line and see if there are any eye exercises you can do to improve your vision. Hope this helps.

Answer 2

Unfortunately, there is no cure for old age, although today cataract removal surgery is quite common and a big help.

It is wise to follow a healthy lifestyle. Overweight leads to high blood pressure and diabetes. High B.P. required use of meds which may affect vision, and diabetes definitely does. The most effective treatment is exercising willpower to eat sensibly and exercising the body to burn calories, build bones, and increase mobility.

Beta Carotine is a good suppliment to help with your eyesight. Also bee pollen, and a product called "Eye Caps" is good for night vision deficiencies.

Hope this helps you.
