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.
The body contains its own “sunscreen,” which is melanin. Dark-skinned people have more melanin and Continue reading “Sun Protection for the Eyes: Prevent Eye Injuries, Cataracts, ARMD, Surfer’s Eye”
Research is pointing toward a link between myopia and the brain chemical dopamine. All-natural sunlight may be the antidote.
Myopic macular degeneration (MMD) arises primarily from genetic abnormalities. 30% of all cases were present at birth; 60% of all cases develop before the child is 13. It often continues to worsen, becoming quite severe myopia by the late teens or early 20s and by 60, 50% of MMD patients are legally blind.
Electronics have become primary obsessions in our personal and work lives. This has lead to nearly everyone becoming susceptible to Computer Vision Syndrome. Symptoms include dry eyes, eye strain, blurred vision, headaches, double vision, difficulty in concentrating, fatigue and/or and head, neck and shoulder pain.
Myopia, also called “nearsightedness,” is a common eye condition that requires correction with eye glasses. If severe, it can lead to serious eye conditions. Myopia is a refractive error in which close objects are clear, but distant objects are blurry. This is because the refracted image is in focus in front of the retina. Typically, the myopic eye is elongated; however, myopia can also be caused by a distorted cornea.
Children are under a great deal of pressure to excel in their studies in Southeast Asia, and a new study in The Lancet shows they may by paying the price by damaging their eyes. Myopia, or nearsightedness, used to have a rate of 20% to 30% on average in Southeast Asia. A recent study put that number at more than 80% in young adults.
The rise of myopia, also known as shortsightedness, has increased significantly in the past 30 years in the United States. Time spent outdoors has dropped off in this time period. Researchers at the National Eye Institute conducted a study of children and teens that shows a possible link between less time spent in outdoor activity and myopia.
