The myopy (short vision)
The myopy, also known as short vision, is a refractive error, that means that the eye doesn’t refract the light adequately for the images to be clear. When a myopy occurs, the objects nearby are seen very clearly, but the distant ones look blurry. This is a common condition that affects a lot of people of different ages. This eye disorder is related to focusing and not with a disease.
High myopy :
A mild myopy is called low myopy. A severe myopy is called high myopy. A high myopy generally settles down between the ages of 20 and 30 ages. A high myopy, normally can be corrected easily with eyeglasses, contact lens or in some cases, with refractive surgery.
Myopics have a higher risk of developping a retinal detachment. Your ophthalmologue will discuss with you the alarming symptoms of the retinal detachment, and also tell you if you are in a position that needs immediate attention or not. İf a retinal detachment occurs and is diagnosed in time, a surgical procedure can usually repare it. İt is important to undergo eye examinations regularly, to control the changes of the retina and prevent a retinal detachment in case if one is starting to happen.
The myopics also have a higher risk of developping glaucoma and cataracts.
Causes of the myopy :
For making our eyes able to see, the light rays have to be doubled or refracted through the cornea and the crystalline and thus focused in the retina which is the layer of photosensitive cells that coats the back of the eye. The retina receives the image formed by the light rays and sends it to the brain through the optical nerve.
The myopy occurs when the eye is larger than normal or has the cornea too curved. As a result, light rays are focused in front of the retina and not on it. This allows you to see clearly nearby objects, but the distant objects become blurry.
Some signs and symptoms of the myopy include eye fatigue, headaches, the action of squinting to see better and the dificulty to see distant objects like traffic signs for instance.
The myopy symptoms can be evident in children aged between 8 and 12 years old. During adolescence, when the body grows fast, the myopy can worsen. During the ages between 20 and 40 years old, there is generally no changes whatsoever.
Diagnostic of the myopy:
Your ophthalmologue can diagnose a myopy during a full eye examination. He or she will determine if you have a myopy or not while doing a standard eye exam, during which you will be asked to read letters written on a board while staying on the other side of the room.
İf the test shows that you are myopic, your ophthalmologue will use some of his or her devices to learn the cause of the myopy. While directing the brightness of a special light at your eyes, a retinoscope is used to see how the light is reflected from the retina. As the light is reflected from the inside of the eye, this device can indicate if a person is myopic or farsighted.
Your ophthalmologue will also use a foropter, which is an instrument that measures the quantity of refraction errors that you may have, and helps to determine the right prescription to correct them.
There is no “better method” for correcting the myopy. The most proper correction for you depends on your eyes and on your life style. Talk about your life style with your ophthalmologue to determine which type of correction is most effective for you.
Eyeglasses or contact lens are the most common methods for the correction of the myopy symptoms. These help the reorientation of light rays on the retina, compensating for your eye’s shape.
They can also help you to protect your eyes of the dangerous UV rays.
İn most cases, people can opt for correcting the myopy with LASİK or other similar refractive surgery. These surgical procedures are used to correct or improve your vision during the remodeling of the cornea, or the frontal surface of the eye, thus adjusting effectively the focusing capacity of the eye.
