Patients with early Age-Related Macular Degeneration (AMD) improved when taking a combination of nutrients. The nutrients were acetyl-L-carnitine, omega-3 fatty acids, and coenzyme Q10.[1. Ophthalmologica. 2005 May-Jun;219(3):154-66. “Improvement of visual functions and fundus alterations in early age-related macular degeneration treated with a combination of acetyl-L-carnitine, n-3 fatty acids, and coenzyme Q10.” Feher J et. al.]
The double-blind trial was controlled with a soy oil placebo. The study included over 100 patients with AMD. They were assigned to take two capsules per day for 12 months of either the treatment capsule or the placebo. Nearly all of the subjects who took the supplements for one year showed significant improvement in visual acuity (Snellen Chart & ETDRS chart), foveal sensitivity and changes in the back of the eye. The fovea is the only part of the eye where 100% visual acuity is possible. Only 2% of these subjects had clinically significant worsening of their condition. But 17% of the control group who received a placebo got worse.
Astaxanthin is an extremely powerful antioxidant that is sometimes overlooked. It protects the body from free radical damage. Ten times more powerful than beta-carotene, astaxanthin is a carotenoid that can cross the blood-brain barrier[1. Tso and Lam 1996]. This means it can reach the retina and macula of the eye.
The sun sustains life, but it also can harm our eyes. Unsafe sun exposure causes or may contribute to several eye conditions and diseases. It can also cause eye injuries. Earth’s ozone layer absorbs most of the ultraviolet (UV) light from the sun, but chemicals have damaged it. Therefore, we must take extra precautions to prevent cataracts, age-related macular degeneration, ocular melanoma (eye cancer), and eye injuries such as pterygium (Surfer’s Eye), photokeratitis (snow blindness), and flash blindness. The sun is also a driving hazard when low on the horizon.
Sunglasses are the primary way to protect your eyes from the hazards of excess sunlight. Ultraviolet (UV) light from the sun can cause cataracts and macular degeneration, serious eye diseases. It can also cause growths on the eye, eye cancer, retinal burns, and 
A homeopathic eye drop called Pleo-MUC (Mucokehl) is designed to increase circulation and reduce congestion in the eye. The drops are aimed at helping dry, irritated eyes. They are indicated for cataracts, glaucoma, dry eye syndrome and conjunctivitis.
Several studies have indicated saffron’s power to protect the eye from the effects of Age-Related Macular Degeneration (ARMD). This precious yellow & red spice contains the carotenoids crocin and crocetin, antioxidants that appear to protect the retina. Visual acuity has been shown to be improved in Macular Degeneration patients who take a saffron supplement. These supplements may also increase blood flow to the retinal area, improve light sensitivity, and reduce photo-oxidative damage.
Middle-aged people and seniors are far more likely to develop Macular Degeneration, glaucoma, cataracts and diabetic retinopathy than those in their youth. It is true that some eye diseases strike the young. These tend to be genetically-based diseases, and they are rare. The incidence of eye diseases in the United States goes up dramatically with age: 
Research is pointing toward a link between myopia and the brain chemical dopamine. All-natural sunlight may be the antidote.
Some patients with dry Age-Related Macular Degeneration (ARMD) have vision improvements after taking high doses a statin. The common cholesterol-lowering drug is called Atorvastatin. It is the statin drug used in a phase I/II clinical trial at Massachusetts Eye and Ear at Harvard Medical School and the University of Crete. A higher-than-normal dose of the drug caused lipid deposits behind the retina to dissolve in some patients.
A new “smart” contact lens has been shown to detect accurately intraocular pressure in glaucoma patients. This technology may be useful for predicting which patients are deteriorating rapidly. Their treatment plan can be modified accordingly to help preserve more vision.
