About your eyes
The following symptoms may indicate a serious eye disease: light flashes, floaters, pain in or around the eye, sensitivity to bright light, excessive tearing, continued redness and blurred vision.
Parents may sometimes think their child is lazy or has a low I.Q. because of poor school work or trouble in learning to read or to spell.
Eyeglass lenses do not strengthen your eyes, they focus the light rays for a clearer image.
Medical records at a large university Headache Centre revealed that only 1% of headaches were caused by eye problems.
Understanding how the eye works is the first step in trying to understand eye diseases.
At around age 45, our eyes let us know they're starting to grow old - we say "our arms are not long enough" and we get reading glasses to correct the presbyopia. Every four years or so, you may need stronger reading glasses. This tend to level off by age 70.
Visual acuity refers to the ability to discern fine visual detail. The distance for testing the eye is 6 metres or 20 feet.At this distance the normal eye is at rest.The procedure for measuring the distance vision is done with a Snellen chart. It is specific-sized letters at a routinely-fixed distance.
Ophthalmologists are different from optometrists and opticians in their training and in what they can diagnose and treat. As a medical doctor, an ophthalmologist is licensed to practise medicine and surgery. An ophthalmologist diagnoses and treats all eye diseases, performs eye surgery and prescribes and fits glasses and contact lenses.
