Don't Wear Others' Eyeglasses Even if You Have the Same Eye Degrees

It is a common phenomenon that some people buy a pair of eyeglasses on the roadside stall unceremoniously when they cannot see things clearly. Or they will borrow others' eye glasses, not caring whether they fit them or not as long as they can see more clear with it than without it. Actually, this is harmful to the eyes and may cause damage to the vision.

Take myopia for an example, it is divided into "simple myopia", "compound myopic astigmatism" and "mixed astigmatism" medically. Therefore, for people who suffer from myopia, they need an optometry conducted by the professionals before filling a prescription if they want to correct their visions. After filling the prescription, the repeated try-on is also necessary to get a proper pair of eyeglasses.

If someone wears other's eyeglasses, as there is a difference between the diopters of different people the focus cannot fall on the retina when the light enters the eyes, so that he cannot see things clearly. Even if he can force himself to see clearly, he is unable to persist for a long time because his eyes will be painful or swollen if he wears such inappropriate glasses for a long time, what's worse, his nearsightedness will be aggravated continuously.

Some people say, "Our eyeglasses have the same degrees, so is it suitable to exchange them for wearing?" Of course not! Although the glasses have the similar or same degrees, but don't forget that pupil distance also plays an important role. Pupil distance means the distance between the pupils of the two eyes. When we are filling a prescription, the optometrist will measure our pupil distance first and then make the glasses for us. The distance between the centers of the two lenses, namely the optical centers, are just the pupil distance. This is the part with the maximum diopter. If the pupil distances are different, the distances of optical centers are different accordingly. So they are not suitable to exchange for wearing.

For this reason, if we find that we cannot see things clearly, don't wear others' eyeglasses or buy a pair of cheap glasses on the roadside stall since they may do harm to our eyes. Instead, we should go to the formal glass store and ask the optometrist to conduct an optometry on our eyes and measure our pupil distance, and then fill a pair of glasses that is the most suitable to us.
