In order for spectacle correction to bring maximum benefit, you need to choose the right glasses. This should be done exclusively by an ophthalmologist. Entrusting the selection of points to a consultant in a store means entrusting your health to a layperson. Illiterate correction threatens deterioration of vision, appearance of headache, dizziness and progression of eye diseases. How to choose glasses and what you should pay attention to, read on.
Glasses are designed to provide full correction of myopia, i.e. 100% vision. They are used only for viewing remote objects. A person performs work at a distance close to the eyes without glasses. Read about laser treatment of myopia here. If the patient suffers from moderate myopia (from -3 to -6 diopters), the doctor prescribes glasses for permanent wear. And here a person can see both distant objects and objects closer to the eyes. He simply cannot do without glasses.
Sometimes a second pair of glasses or bifocals are prescribed for working at a close distance. The upper half of the lenses of such glasses is intended for the correction of far vision. The lower half corrects near vision. At the same time, the lower half of the glasses is several diopters weaker than the upper half.
