HER parents first observed that their five-year old daughter would draw her face too close to the screen when watching TV. They later found out that the girl could not see the images on the television clearly because she was initially suffering from Leber congenital amaurosis, an eye disease that mainly affects the retina, the tissue at the back of the eye that detects light and colors. This eye impairment is said to be hereditary and can be initially noted in the patient during infancy.
Genetics is one prime cause of vision problems. Many eye health care specialists, however, also trace the leading factors of eye diseases today due too much exposure to sunlight or the lack of it; and the too much contact to gadgets, cellphones, and computers since the recent dawning of the digital age.
A previous study conducted by the University of Arizona listed about 350 eye diseases that are obtained genetically. These include, to name a few, albinism, anircidia, colorblindness, corneal dystrophies, glaucoma, keratoconus, Leber congenital amaurosis, night blindness, retinitis pigmentosa, and retinoblastoma.
These eye disorders can be quickly corrected and prevented from further sight deterioration if only given top attention at once. Leading ophthalmologists in many parts of the world recommend respected eye health care centers like the United States-based Costco Optical, which is attached to the huge Costco Wholesale Corporation. It is a membership-only, or exclusive, warehouse club with branches spread in many parts of the world like Canada, United Kingdom, Australia, Mexico, Taiwan, South Korea, Japan, and Spain.
Or if needing eyeglasses that correct any of these vision problems, there is the Pearle Vision, a chain of optical stores with headquarters in Savannah, Georgia, and founded by Stanley Pearle who has been in eye disorder correction and protection business for over 50 years. Its chains in other countries are called Pearle Optical.
Another leading cause of eye problem today is too much exposure to the sun. Photokeratitis is one of them. It is a swelling or inflammation of the cornea, which covers the eye, is manifested by redness, blurred vision, welling of tears, light sensitivity, or general eye pain. Eye doctors also refer Photokeratitis as snow blindness. Welders are some of the people who are more prone to this eye disease. But photokeratitis is said to be a “temporary condition” and can be cured with antibiotic and eye drops. A dab of cold compress also helps, the doctors say.
Pinguencula is another eye problem caused by long hours of exposure to the sun. It is a white or yellow lump in the conjunctiva, the soft layer that covers the white of the eye. This eye disorder common in those who reside in either in sunny, dry, sandy, or dusty areas. Tis can be prevented by using sunglasses and when the eyes are swelling, they can use medicinal eye drops.
Pterygium is caused by the growth of a pinguencula of the cornea due to long exposure to the sun. If unchecked at once, this may scar the cornea and may lead to permanent loss of vision. When worsened, surgery is recommended to remove it. Sun visors, shades, and other eye protection gears can be used to minimize the rate of sun exposure.
Cataract is one common eye defect caused by long exposure to the sun. To avoid having cataract, doctors recommend healthy diets that include green leafy vegetables and fruits. UV400 sunglasses can best protect the eyes. If smoking, stop it.
Macular degeneration, the other eye defect caused by long hours of exposure to the ultraviolet rays, most usually occur in people aged 50 and above. Thus, the so-called AMD or the age-related macular degeneration. Long hours of staying under the sun damage the retinal tissue of the eye – or the multi-layered lining inside the eye, the macula. Macular degeneration blurs vision and leaves blank space in the eye. There is no reported cure yet for macular degeneration. Treatments recommended by ophthalmologists only slows down the progress.
These are the main ailments caused by long hours of staying under the sun. However, those working in closed and well-ventilated offices may also be missing vitamin D. They also have to find time to go out and bask under the sun to get one of the most needed nutrients of the body, especially the eye: vitamin D.
The latest culprit in the present-day occurrences of eye disease is the inevitable coming of computers and other computer-run gadgets, including cellphones. Many people welcome with open arms the coming of the so-called digital age There are reports, however, that myopia, a common vision issue in which the afflicted can see objects clearly when near but burred when far. It is because the shape of the eye refract incorrectly – or the object is seen in front, instead of on, the retina. Reports reveal that some 75% of adults in the United States are suffering from myopia since the virtual invasion of the so-called high-technology.
