Visual impairments: What is myopia and how do you treat it?
All forms of visual impairment are unpleasant and restricting. However, with the help of contact lenses and glasses, you can manage most of your everyday life activities without problems.
Today we are focusing on myopia, also known as shortsightedness.
What is myopia?
If you see objects close up sharply, so you don't have a problem reading small print, but see things blurred in the distance, you're probably shortsighted. Your eyes suffer from a condition called myopia.
Myopia is the most common cause of vision problems in people under 40 years of age.
It is a common visual impairment in which objects in the vicinity can be seen clearly, but objects in the distance are blurred. It occurs when the shape of your eye causes the light rays to bend (break) incorrectly and focus images in front of the retina instead of on the retina.
Myopia can develop more or less gradually and often worsens during childhood
and adolescence. It also tends to be inherited.
What are the symptoms of myopia?
The symptoms include blurry vision when looking at distant objects, the need to squint or partially close the eyelids to see more clearly, and eventually headaches may be caused by eyestrain.
However, myopia is often detected at first during childhood. If you're wondering whether your kid suffers from myopia, pay attention to the symptoms below.
If your kid:
- persistently squints
- needs to sit closer to the TV or needs to be placed in the front of the classroom at school
- cannot detect remote objects
- blinks excessively
- rubs her or his eyes frequently
she or he could be short-sighted.
Note: If you detect any of these symptoms in your child, please see an eye
doctor or optometrist to give them an eye test. They will find appropriate contact lenses or glasses for you kid.
What causes myopia?
Myopia occurs when the eyeball is too long and doesn't support the focusing power of the cornea and lens. Thus the light rays focus on a point in front of the retina and not directly on its surface.
Myopia can also be caused by the cornea and/or lens being too curved for the
length of the eyeball. In some cases, myopia is caused by a combination of these

How is myopia treated?
You can correct myopia with contact lenses, glasses or refractive surgery such as LASIK.
Contact lenses provide optimal visual acuity, even with severe myopia. After the refractive power of your eye and your corneal surface have been measured, your eye doctor or optometrist selects the appropriate contact lens for your eye from various contact lens types in order to correct it. If you follow the lenses' care instructions and have regular check-ups, you can wear contact lenses for a long time without any problems.
Concave contact lenses are the best way to treat myopia. They work by bending
the light rays slightly outwards so that they can concentrate further back onto
the retina. Prescriptions for concave contact lenses have a minus sign in front
of the number. The further away the number is from zero, the higher the
