Is a freckle in the back of my eye serious?
A freckle in the back of the eye refers to a choroidal nevus, a common, benign, flat, pigmented growth under the retina. Such nevi almost always have no effect on vision. However, if growth of a nevus is documented by periodic observation or photographs of the retina, it may be undergoing transformation into a malignant melanoma of the eye. You should have your "freckle" checked by an eye doctor.
How bad is it to sit in front of a computer screen for hours each day?
Computer vision syndrome refers to eyestrain resulting from long-term computer use. Although this condition doesn't have serious or long-term consequences, it is disruptive and unpleasant. Besides being uncomfortable, CVS might lead to general fatigue and an inability to concentrate. Constant close work with a computer or blackberry may cause progressive near sightedness. In the last 25 years, the incidence of near sighted adults has gone from 25% to 42%.
Eyestrain causes sore or burning eyes, a sore neck, blurred vision, wet or dry eyes, headache, and sensitivity to light. Working at a computer might also produce color afterimages when looking away from a monitor or disrupt the ability to shift focus between a monitor and paper documents. Using proper lighting can be an excellent way to minimize the effects of computer vision syndrome. When using a computer, try to dim the ambient lighting to about half of what is normal for an office. You may want to use less bulbs or bulbs at a lower wattage for this effect. Also, try to position your monitor so that any exposed windows are at a right angle to the computer screen.
Another way to minimize eye strain from the computer is to take a series of short, fiveminute breaks throughout your workday. Stand up, stretch, and focus on things other than your computer screen. These breaks tend to improve overall productivity, so you likely won't be losing any work time. While working, try to blink frequently to rewet the eyes. About every twenty minutes, blink slowly about ten times, which should help to provide needed moisture. Also, practice some simple exercises that will help the eye relax and easily refocus. Every so often, look away from the computer screen and gaze at something far away in your field of vision. Or, alternate between focusing on a close object and then a distant object for about ten seconds each, which will help condition the eyes to refocus effectively.
Integrative Health Solution:Have an eye exam to make sure you wear the correct glasses. Avoid staring during close work and take periodic breaks every 20 to 30 minutes. Make sure Omega 3 fatty acids are in your daily vitamin regimen and diet.
What are the symptoms of uveal coloboma?
Honor Society of Nursing (STTI) answered
There may or may not be any symptoms related to coloboma; it all depends on the amount and location of the missing tissue. People with a coloboma affecting the macula and the optic nerve will likely have reduced vision. In general, it is difficult to exactly predict what level of vision a baby will have only by looking at how much of the retina is missing.
People with coloboma affecting any part of the retina will have what is called a field defect. A field defect means that a person is missing vision in a specific location. Because coloboma is located in the lower part of the retina, vision in the upper part of the field of vision will be missing. This may or may not be noticeable to the affected person.
A person with a coloboma affecting the front of the eye only will not have any decreased vision from it. Some people, however, have reported being more sensitive to light.
