Fluids. Drinking large amounts (a quart or more) of any liquid within a short time, about 30 minutes, appears to increase pressure. Patients with glaucoma should have plenty of fluids, but they should drink them in small amounts over the course of a day.

Sunglasses

Glaucoma can cause the eyes to be very sensitive to light and glare. Medications can worsen this problem. Sunglasses solve this problem and are important for prevention of cataracts. Protective sunglasses do not have to be expensive. But it is important to select sunglasses whose product labels state they block at least 99 percent of UVB rays and 95 percent of UVA rays.

Polarized and mirror-coated lenses do not offer any protection against UV radiation. It is not clear if blue light-blocking lenses, which are usually amber in color, provide UV protection.

Herbs and Supplements

Generally, manufacturers of herbal remedies and dietary supplements do not need FDA approval to sell their products. Just like a drug, herbs and supplements can affect the body's chemistry, and therefore have the potential to produce side effects that may be harmful. There have been a number of reported cases of serious and even lethal side effects from herbal products. Always check with your doctor before using any herbal remedies or dietary supplements.

A number of herbal and nontraditional remedies have been advertised as glaucoma remedies. A few studies have reported that the herbal remedy ginkgo biloba may have properties that offer benefits to patients with glaucoma, including increasing blood flow in the eye without altering overall blood pressure, heart rate, or intraocular pressure. More research is, however, needed. There is no evidence that bilberry, another popular herbal remedy for eye disorders, is effective in preventing or treating glaucoma.
