What reason is eye flatlight

summary

Hyperopia refers to the optical focus falling behind the retina after the parallel light enters the eye. So the image of the object formed on the retina is blurred. Scientific research has found that by using the regulating force to move the focus behind the retina to the retina, we can see the distant object. Patients are prone to eye fatigue. For the patients with mild hyperopia, the refractive defect can be overcome by wearing glasses to adjust the power, and there can be no visual symptoms in life. For teenagers, their adjustment power is strong, even if they have mild hyperopia, they can not have any visual symptoms. However, for some patients with high hyperopia, the visual symptoms are more obvious because they can't see the outside objects clearly.

What reason is eye flatlight

First: the most common symptom of hyperopia is asthenopia, patients are easy to feel eye fatigue. Some patients will also feel headache, as well as physical and mental discomfort. If the patients maintain visual fatigue for a long time, they can not get timely treatment. If visual fatigue lasts too long, they are prone to high visual impairment, which is caused by cycloplegia. However, spasmodic contraction of ciliary muscle may also occur, leading to pseudomyopia.

Second: the treatment of hyperopia. Patients with poor eyesight should pay special attention to their own eye protection. Generally speaking, for patients with mild hyperopia, if hyperopia has not caused visual impairment, no visual fatigue, and the patient's physical health is still good, then there is no need for correction.

Third: however, if patients do not meet the above conditions, they have to wear appropriate glasses to correct. Patients should be optometrically corrected with convex lenses. For children and adolescents, it is particularly necessary to pay attention to the regular ophthalmic examination in professional ophthalmology.

matters needing attention

Although there is no method to prevent hyperopia at present, the following methods are good for the eyes of patients with hyperopia: develop good eating habits and living habits, diet should eat more food rich in vitamin A and vitamin C, develop the habit of drinking more water, so as to prevent dry eyes, and is good for health. In hot weather, you should wear sunglasses to prevent excessive ultraviolet radiation.
