Myopia, or nearsightedness
, is a refractive error in the eye, which makes it unable for people to
clearly see objects that are slightly at a distance. People who are nearsighted won’t have
problems doing close-up tasks like using the computer or reading, but they could find it hard to
read road signs.
What are the symptoms of myopia?
Myopia can cause symptoms such as eyestrain, squinting, headaches, or fatigue while
performing activities like playing sports, driving, or looking at objects more than a few feet
away. The main symptom, however, is blurry vision when looking off in the distance
What causes myopia?
Since myopia is a refractive error, it structure of the eye, and is caused by abnormalities in its shape and size. The eyeball in nearsighted
people is too long or the cornea can have very high, steep curvature. This causes the light entering the
eye to become unfocused. Images are focused in front of the retina, which is the light-sensitive
part of the eye, instead of being focused on the retina, and this results in blurred vision.
Typically, myopia can begin in childhood, and people have higher chances of developing this
condition if their parents are nearsighted. In most cases, myopia stabilizes during early
adulthood, but in some cases, it can continue to worsen with age.
How can you treat nearsightedness?
Myopia can be corrected with contact lenses or glasses. It can also be repaired using refractive
surgery, such as LASIK surgery
. Nearsighted people may need to wear their glasses or contact lenses during the entire
day or only specific times during the day when they require clear distant vision depending on the
degree of their condition. It is important that they wear their lenses or glasses while driving or
performing other tasks which could lead to accidents in case of inattentiveness.
