what is long sightedness ? how is it corrected
Answers
Answer:
Long-sightedness can usually be corrected simply and safely by wearing glasses with lenses that have been prescribed specifically for you. See diagnosing long-sightedness for more information about what your prescription means.
Wearing lenses that have been prescribed specifically for you will ensure that light is focused onto the back of your eye (retina) correctly, so that close objects do not appear as blurry.
The thickness and weight of the lenses you need will depend on how long-sighted you are. Long-sightedness can get worse with age, so the strength of your prescription may need to be increased as you get older.
Some people are eligible for help with the cost of glasses frames and lenses, for example, if you are under 16 years of age or if you are receiving Income Support. Find out more about NHS eyecare entitlements to check if you qualify.
If you're not eligible, you'll have to pay for your glasses. The cost can vary significantly, depending on your choice of frame. Glasses start at around £50, with designer glasses costing several hundred pounds.
