I'm in my late 40s and I have had to wear glasses for nearsightedness for 20 years. Lately, however, I've begun to have difficulty reading with my glasses on. My doctor told me it was a common occurrence and said I would now need bifocals. I hate wearing glasses. Is there anything that can be done?
A loss of flexibility in the lens of your eye is most likely responsible for the changes in your vision. Your doctor was correct when he stated that bifocals are commonly required at your age. With age, the eye's lens becomes less elastic and its ability to focus becomes impaired. If the situation hasn't progressed too far, you may be able to prevent the need for bifocals by increasing glutathione levels.
Glutathione performs important functions relating to the lens of the eye:
- It aids in transporting the minerals calcium, potassium, and sodium in and out of the lens.
- It protects certain proteins from oxidizing and slows the breakdown of DNA within the lens.
Without adequate amounts of glutathione, each of these processes will continue unabated and lead to a hardened, inflexible lens. Any adverse change in the lens of your eye is a fairly reliable indication that your glutathione levels are declining, and this includes the formation of cataracts.
How to Slow Changes to the Eye's Lens
You may be able to reverse the changes in your lens by combining some dietary changes with specific nutritional support aimed at optimizing glutathione levels. Here's how:
- Increase your glutathione level. You can do this by taking either glutathione tripeptide (500 mg daily) or a precursor of glutathione, N-acetylcysteine (500–600 mg daily).
- Take a multivitamin/mineral that contains selenium. This mineral is necessary for glutathione to work properly.
- Take at least 1,000 mg of vitamin C daily. Vitamin C helps "recycle" used glutathione.
- Increase your consumption of glutathione-rich vegetables. These are the cruciferous vegetables like Brussels sprouts, cauliflower, broccoli, cabbage, kale, bok choy, cress, mustard, horseradish, turnips, rutabagas, and kohlrabi.
If you act fast enough, you should be able to delay the immediate need for bifocals and possibly eliminate the need for them altogether.
