What are different types of nearsightedness?
myopia, otherwise known as short attention or nearsightedness, is one type of eye defects that may occur. Five main classifications for this condition are induced, degenerative, pseudomyopia, simple and night. The classification of the state depends on the severity and symptoms. It is known as a refractive disorder. In the normal eye, light passes and the retina focuses on light. From the retina, messages are sent to the optical nerve, where the brain processes signals into images. People with nearsightedness see blurred images from a distance, because the retina did not focus properly. Short observations may be caused by excessive exposure to prescription drugs. It can also be caused by nuclear sclerosis or increased glucose. The belts used to repair the retina separation can stretch the length of the eye, which also leads to a short observation. This category is progressive, which means it deteriorates over time. In this case, the eye continues to increase and blurry vision increases. This is due to the growing distance between the outerm eye and retina.
Another type of nearsightedness is pseudomyopia. This form is temporary and occurs when ciliary muscle cramps. The ciliary muscle is muscles in the eye that controls focusing skills. Muscle cramps make natural or manual focusing capabilities, leading to blurred images in the distance.
Simple myopia is the most common form of this condition. The eye of the patient is too long for the optical power it has. Genetics and environment can lead to the development of this form. Over time, it usually does not proceed and is often easier to.
Night myopia is classified when one has difficulty visiting things far when low lighting occurs, but daily vision is normal. Pupils extend and limit themselves in response to light levels. When pupils are expanding to allow more light to the eyes, images are distorted.
Most of myopia cases can be treated. To repair this state exiThere are three methods. Real lenses are special glasses or prescription contacts. Some people with more serious vision problems can also decide to undergo a corrective operation.
