Vision problems affect millions of people around the world. Myopia, the formal name for myopia, is a condition in which light is not properly focused through the lens. The result is that objects that are far away appear blurred, while objects near the face appear normal and clear. Thus, this disease is also called myopia.
Myopia is a kind of anisometropia, with the symptom that the patient can see nearby items but cannot see far. It is a refractive error of the eye in which collimated light causes the image to focus in front of the retina when the accommodation is relaxed. If you suffer from the same vision problem, it is better to go to a professional eye doctor as soon as possible.
Myopia occurs in a variety of forms classified according to the age of onset, as well as the severity of the disease. In the age spectrum, the following types are recognized:
Congenital myopia is present at birth due to genetic defects.
The onset of youth, also called childhood myopia, tends to occur in school-age children.
The disease that begins in adults will affect people over the age of 20.
In addition to the age of onset, we can classify myopia according to severity. Small, medium and high myopia are recognized. Each is divided according to how strong a corrective lens should be to clarify the vision. Severe myopia is the most severe and may increase the risk of retinal detachment and glaucoma. Retinal detachment is a serious condition in which the retinal tissue detaches from its support. If not addressed immediately, it can lead to blindness.
A number of variants of the disease are also recognized in the clinic. Degenerative myopia is one of the few progressive forms, which means that it will worsen over time. Night myopia is a condition in which blurred vision is exacerbated in low light conditions. Induced myopia is a condition in which a healthy person acquires the disease. This may be the result of hyperglycemia or side effects related to pharmaceutical agents.
There are now many methods for controlling myopia. There is no method to prevent the disease, but the clinical myopia management is relatively simple. Traditionally, eyeglasses that act as corrective lenses have been commonly used for centuries. Modern myopic treatments include contact lenses that sit directly on the eyeball and help refract light. Another treatment for myopia that has gained popularity in recent years is refractive surgery. This procedure is usually performed using lasers to reshape the cornea and optimize its light bending abilities. If myopia is too severe for this type of surgery, a new procedure is available. This procedure involves implanting a small lens inside the eye to treat a variety of disorders, including myopia. These treatment options tend to be very safe and have a strong history of visual improvement.
