Minus eyes or nearsightedness have the medical term myopia. This condition causes you difficulty seeing objects remotely.
The light reflected from an object enters the eye through the cornea, then is focused by the lens of the eye into the retina. In normal eyes, the lens of the eye and cornea refract the incoming light so that the shadow of the object is focused right on the retina. While in the minus eye, the incoming light is not focused on the retina, but far ahead of it. This can be caused by the cornea being too convex or the length of the eyeball being too large. So if you have a minus eye, when viewing objects from a distance, the object will look out of focus.
The magnitude of minus eye severity is indicated by the size of the diopters (D). Based on the severity, minus the eye is divided into three, namely low myopia (minus 0.5D to minus 3D), moderate (minus 3D to 6D), and severe (above 6D).

When to Start Checking Eyes?
As you age, the sharpness of your eyes decreases. If you experience some of the above symptoms, or have the possibility of experiencing eye damage, you should check your eyes.
If there are no visual complaints, adults are still recommended for routine eye examinations starting at the age of 40 years. At the age of 40 to 54 years, eye examinations can be done every two to four years. At the age of 55-64 years, every one to three years. And at the age of 65 years and over, the examination can be done every one or two years.
In children, it is better to begin an eye examination just before school. When starting to enter school, do routine every one or two years.
Minus Eye Therapy
If it turns out your eyes have already experienced minus eye disorders, then you can do some therapy like using glasses or contact lenses. Glasses are one of the easiest and safest ways to correct minus eyes. However, in glasses for a heavy minus, vision at the edges can cause visual distortion. Contact lenses don’t have these disadvantages, but their maintenance is relatively more complicated than glasses.
For those of you who want permanent eye correction, you can choose the operating path. Some surgical options that you can do such as LASIK surgery, LASEK surgery, and photorefractive keratectomy (PRK). In addition, for patients with moderate to severe minus the eye, intraocular lens (IOL) implants can be an option.
Like surgery, minus eye surgery through surgery also has side effects or complications that may occur. Among other things, the eyes become dry, infections, and scarring arises in the cornea.
Minus Eye Complications
Damage to the eye can interfere with daily activities and reduce quality of life. If you force driving in minus eye conditions without wearing glasses, it will certainly jeopardize your safety.
Forcing to see with minus eye conditions can also make your eyes tense because they are forced to see or focus objects. This condition can also cause headaches.
Severe minus eyes will increase the risk of serious eye disease, including retinal detachment (retinal detachment). Glaucoma and cataracts can also occur.
