How many degrees is 45 vision

In recent years, children's eyesight has been declining sharply, and more and more people are suffering from myopia, which is mainly caused by excessive exposure to electronic products for too long in daily life. The eyesight of many children is worse than that of adults, so they have to wear corrective glasses, but these glasses cannot necessarily restore vision to normal values. The main thing is to protect the glasses themselves. So what is the exact degree of 45 vision?

1. How many degrees is 45 degrees of vision

Generally, a 45-degree myopia requires 125-degree myopia glasses, but everyone's eyesight is different, so you have to experience it to know. However, it must be low myopia, and the corrected vision is the vision level after wearing glasses.

A visual acuity of 45 only means poor vision, which is not necessarily caused by myopia. It can only be said that myopia is the most likely cause, and myopia is the most optimistic reason for poor vision. If you want to be clear, it is best to go to the hospital for mydriasis and eye examination. At this age, slow dilation and eye examination are also required. Although the process is relatively complicated, the results will be more accurate.

2. What are the effects of myopia?

1. Eye fatigue

Due to unclear vision, the eyes increase their accommodation, and the eye muscles are in a state of excessive tension for a long time, which can easily cause eye fatigue. Symptoms such as eye swelling, eye pain, orbital pain, dizziness, and nausea may occur.

2. Macular hemorrhage and degeneration

Degenerative myopia is caused by lesions in the fundus, which can cause macular hemorrhage, atrophy and degeneration of the retina and choroid, and seriously affect vision.

3. Causes strabismus

After myopia occurs, the eye uses less accommodation and more convergence when looking at close objects, which causes an imbalance between accommodation and convergence. The medial rectus muscle is in a state of excessive tension for a long time. Over time, this causes insufficient function of the medial rectus muscle and a corresponding weakening of the convergence function of both eyes, which can easily lead to exotropia or exotropia.

4. Retinal detachment

Due to the elongation of the eye axis and the liquefaction and degeneration of the vitreous body, the fibrous cords in the vitreous body can adhere to the retina and pull on the retina. When the eyeball is impacted or traumatized, it can cause retinal rupture and retinal detachment. Retinal detachment is the most serious complication of high myopia, and vision is extremely reduced. If not treated in time, it can lead to blindness.
