Glasses for short-sighted or minus people. For me personally, without these glasses, the view as far as 2 meters will look blurry. The left and right glass have different minus values. The left eye of minus reaches 1.50D. While the right eye is only minus 1D.
Taken from www.aoa.org-- Farsightedness, or hyperopia, as it is medically termed, is a vision condition in which distant objects can be seen clearly, but close ones do not come into proper focus. Farsightedness occurs if your eyeball is too short or the cornea has too little curvature. In these cases, your eye can't correctly focus the light that enters it.
Common signs of hyperopia include difficulty concentrating and maintaining a clear focus on near objects, eye strain, fatigue and/or headaches after close work, aching or burning eyes, and irritability or nervousness after sustained concentration.
While the second source that I reads told the minus or farsighted eyes have a medical term myopia. This condition causes you trouble viewing objects remotely.
The light reflected from an object enters the eye through the cornea, then focused by the lens of the eye to the retina. In the normal eye, the lens of the eye and the cornea refracts the incoming light so that the object's image is focused right on the retina. While in the eye minus, the incoming light does not focus on the retina, but far ahead of it. This can be caused by the cornea is too convex or the length of the eyeball is too large. So if you have a minus eye, when viewing the object remotely, the object will look unfocused.
The severity of minus eye is indicated by the size of diopters (D). Based on the severity level, the minus eye is divided into three, namely low myopia (minus 0.5D to minus 3D), medium (minus 3D to 6D), and weight (above 6D).

When to Start Eye Check?
As you grow older, the sharpness of your eyes will diminish. If you experience some of the above symptoms, or have a chance of experiencing eye damage, you should check your eyes.
If there are no vision complaints, adults are still recommended for routine eye examination from 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's good to start having eye examinations before school. At the time of entering school, do a routine every one or two years.
Minus eye therapy
If it turns your eyes have already experienced minus eye disorders, then you can do some therapy such as using glasses or contact lenses. Eyeglasses are one of the easiest and safest ways to correct the minus eye. However, on the glasses for a heavy minus, a view on the edges of vision distortion can occur. Contact lenses do not have these deficiencies, but maintainers are relatively more complicated than glasses.
For those of you who want permanent eye correction, you can choose the path of operation. Several options of surgery you can do such as LASIK surgery, LASEK surgery, and photorefractive keratectomy (PRK). In addition, for patients with moderate to severe eye, an intraocular lens implant (IOL) may be an option.
Appropriate surgery, eye therapy minus through surgery also has side effects or complications that may occur. Among other things, the eyes become dry, infection, and arising scarring in the cornea.
Minus eye complications
Eye damage can interfere with daily activities and decrease quality of life. If you force driving in minus eye conditions without the use of glasses, it will certainly endanger your safety.
Forcing a look with a minus eye condition can also make your eyes tense as it is forced to see or focus the object. This condition can also cause headaches.
A heavy minus eye will increase the risk of serious eye diseases, including retinal detachment (retinal detachment). Glaucoma and cataracts can also occur.

Minus eye can not be prevented, but can be slowed its development. Take care of your eye health by doing the following things:
Eat a healthy diet. It is common knowledge that eating healthy foods can keep organs healthy, including the eyes. Begin to multiply the consumption of fruits and vegetables. In addition to carrots, egg yolk and milk also contains lots of vitamin A which is useful for eye health. Fish rich in omega 3, such as tuna, salmon, and mackerel, are also good for mat health
Avoid cigarettes. Smoking is not good for health and can also affect eye health.
Use sunglasses with UV protector. Do not underestimate the sun, because in addition to making the skin becomes darker, the sun can also interfere with eye health. Wear sunglasses that have UV light protection to maintain eye health.
