Myopia (nearsightedness) - what is it?
Myopia - also known as shortsightedness or nearsightedness - is a condition in which a variation in the shape of the eyeball causes objects in the distance to be blurry, while items that are close up appear perfectly clear.
In the UK, nearsightedness is a common problem. Babies can occasionally be born with congenital myopia, but in most cases, the condition becomes apparent during the various periods of rapid growth between the ages of 8 and 12. Generally nearsightedness is diagnosed before the age of 20; however, adult-onset myopia can also occur after this point. Often the degree of myopia increases as the body grows rapidly, then levels off in adulthood.
During the years of rapid growth, frequent changes in prescription eyewear or contact lenses may be needed to maintain clear vision.
Causes of myopia
The most common reason for having myopia is that the eyeball is slightly too long - rather than the normal rounded shape. Nearsightedness can also be found in people whose cornea - the transparent front part of the eye - is too curved.
There are a number of reasons that a person may become nearsighted. In many cases, it is believed that myopia is caused by genetic factors. Other possible causes for nearsightedness include doing too much close-vision work, which could strain the eyes.
Myopia is often diagnosed after a teacher notices that a child is squinting to see things going on at the front of the classroom. Nearsightedness may also be found during routine eye examinations.
Corrective concave lenses are prescribed to treat nearsightedness. These help to focus light in the proper part of the retina in order to form a clear image.
Once neartsightedness has been found, regular eye examinations should be carried out to determine the amount of correction required and to monitor any further changes in vision. Depending on the patient's age and other circumstances, they may be eligible for free eye exams on the NHS to keep track of the condition.
Depending on how severe the myopia is, glasses or corrective contact lenses may be needed all the time or only sometimes. For slight nearsightedness, corrective lenses might only be required for distance vision like driving or watching television. For more acute shortsightedness, the lenses may need to be worn more often.
Contact lenses for correcting the effects of myopia
If you suspect that you have myopia, the best thing to do is get in touch with your eye care professional. They will be able to carry out a complete examination to ascertain the extent of your vision problems and help you choose the best corrective options.
Once diagnosed with myopia, you'll have a variety of choices for correcting the problem. One popular choice is to get contact lenses. Contacts are often selected due to their effectiveness and ease of use. In addition, they are safe for wearing while playing sports and they don't change your appearance in any way.
