Myopia: Definition, Causes and Treatment

Eyes are the most important and beautiful part of the body, which sometimes becomes your identity. Eyecare is very important. The muscles of the eyes are the most functional in the body. Myopia is the most common cause of impaired vision in people under 40 years of age. Its prevalence is increasing alarmingly in recent years.

Globally, research shows that in the year 2000, about 25 percent of the world’s population was myopia, but by the year 2050, it is expected that about half of the population worldwide will suffer from myopia.

Symptoms of Myopia

If you are myopic, you will have difficulty reading road signs and seeing distant objects clearly, but will be able to see well for close-up tasks such as reading and computer use, and there will be no difficulty.

Other signs and symptoms of myopia include squinting, eye strain, and headache. Feeling tired while driving or playing sports can also be a symptom of myopia that has not been improved.

If you experience these signs or symptoms while wearing your glasses or contact lenses, schedule an eye exam, to see if you desperately need treatment by proper prescription.


What causes myopia?

Myopia occurs when the eyeball becomes too long in relation to focusing on the cornea of ​​the eye and the power of the lens. This causes the rays of light to be positioned directly in front (before the retina), rather than focusing at a point on the surface of the retina.

Too much curving of the cornea and / or lens for the length of the eyeball can also be the cause of myopia. In many cases, a combination of these factors leads to myopia.  

Myopia usually starts in childhood, and you may be at greater risk of getting myopia if your parents also have problems with myopia. In most cases, myopia stabilizes in early adulthood but sometimes it progresses with age.


Treatment of myopia:

Myopia can be corrected with eyeglasses, contact lenses, or refractive surgery. Depending on your degree of myopia, you may need to wear your glasses or contact lenses at all times or, when you need clear vision at great distances, as you see a chalkboard while driving or watching a movie.

Good options for eyeglass lenses for myopia include high index lenses (for thin, light glasses) and lenses with anti-reflective coating. Also, to protect your eyes from UV and high-energy blue light, consider photochromic lenses and reduce the need for sunglasses made by a separate pair of prescriptions.

If you are near-sighted, the first number (“sphere”) will have a minus sign(-) on your glasses prescription or contact lens prescription. The higher the value, the more near-sighted you are.

Refractive surgery can also reduce or eliminate the need for your glasses or contact lenses.

Controlling myopia:

With more people being nearsighted, they are becoming very interested in finding ways to control growing myopia in childhood.

Many different techniques have been tried – including children using bifocal, progressive lenses, and gas permeable contact lenses. However, all these techniques gave mixed results.

Recent clinical trials have shown that low-dose atropine eye drops may slow the progression of myopia in school-age children, with significantly lower side effects compared with high concentration.

However, atropine drops have not yielded good results on some children.

Degenerative myopia:

In most cases, myopia is just a minor inconvenience and there is little or no danger to eye health. But sometimes myopia can be so progressive and severe that it is considered a degenerative condition.

Degenerative myopia (also called malignant or pathological myopia) is a relatively rare condition that is believed to be hereditary/genetic and usually begins in childhood.

In the case of malignant myopia, eyeball growth may occur rapidly, leading to early and severe progression of myopia and loss of vision. In normal people with this condition, the retinal rupture and other degenerative changes in the back of the eye increase to a great extent, such as abnormal blood vessel enlargement, including bleeding in the eye.

Degenerative myopia may also increase the risk of cataract. Get in touch with your eye doctor. If you are having trouble seeing far objects or you find that you are keeping books (or your smartphone) near you to make them look better than words, you will need to contact your eye doctor. Myopia can be treated which in many cases is a slow process for children.
