Most people don't value what they have until they lose it. This truly applies to vision. People don't know they need glasses as a child because they have no frame of reference. Therefore,children's vision must be tested by age 5, especially because 1% of the population has a lazy or unused eye. Only through early diagnosis and treatment can the vision be improved. In this article are two of five common eye problems to consider. The other three (cataracts, glaucoma, and macular degeneration) are detailed in another article.
Conjunctivitis: Redness and swelling of the thin outer coat of the eye, which normally is transparent. It can be caused by infection (eg. pink eye), chemicals, injury, oily skin (rosacea), dry eye, surgery or allergies. Signs and symptoms are discomfort, swelling, itching, redness, tearing, light sensitivity and discharge. Rubbing the eye may increase the problem and, in the case of the infection, spread it to the other eye. Hand washing is extremely important for reducing spread of infection.
Dry eyes: Very common in computer users, the elderly, people on certain medications, people with medical conditions, people in warm, dry environments, and people who don't blink frequently. Remember to think, drink (water), blink, examine medications, eliminate artificial sweeteners (eg. soft drinks) and use artificial tears. The symptom of tired eyes may apply to people with dry eyes, chronic conjunctivitis, wearing the wrong glasses, straining with reading, and the inability to maintain both eyes focusing at the same point. Artificial tears can be tried as a remedy but an examination may be necessary. Many times the bifocal in glasses is not properly set for close work and can lead to eye fatigue.
