Myopic Swimming Goggles Degree Selection

How does myopia swim lens degree choose?

The quality of swimming glasses lens is related to the health of the body, and for the nearsighted swimming glasses is the most important.At present, the nearsighted goggles on the market are basically using plastic steel reinforcement treatment and polycarbonate, silicone and other types, and increased waterproof fog, ultraviolet protection function.

The lens of myopic swimming goggles is divided into two types of surface micro-convex mirror and absolute flat mirror.The surface of the micro convex mirror style and ordinary swimming glasses are no different, this lens in the water to be affected by a certain refraction, so in the process of purchasing, consumers should pay attention to a difference in the calculation.The absolute flat mirror is slightly lower than the average mirror of swimming goggles, the advantage of this swimming goggles is that there is no difference in the water caused by refraction.

The choice of these two types of myopic goggles is not the same.For example, there is a kind of sable brand myopia swimming goggles belong to the absolute plane mirror, when buying can directly according to their own myopia degree of the eye to choose the corresponding.At present, most of the neareyesight goggles are still based on the surface of the micro convex mirror, consumers in the choice of time, generally should be based on their actual degree minus 50-100 degrees to consider the purchase.For example, if your myopia is 500 degrees, then when choosing swimming goggles, you should choose 400 or 450 degrees lenses.

The classification of myopic swimming goggles

1.The first is the myopia swimming glasses that are customized according to the degree of the swimmer's myopia.This kind of nearsighted swimming mirror lens and ordinary glasses lens are exactly the same, according to the swimmer's degree including astigmatism after processing good lens, installed in the silica gel sealed frame, this kind of nearsighted swimming mirror can be 100 percent close to the swimmer's original degree.

2.The second is separate myopia swimming goggles, its principle is to put the picture frame and lenses processing respectively and then assembled, it can also realize around eyes degree different choice, but do not contain astigmatism, at the time of purchase, according to the swimmer swim around eye degrees were about to choose close eyes components, then assembled.The market retail price is around 200.

3.The third kind is more simple and complete integration of myopia swimming glasses, that is, the right and left eye degree and the frame of one shaped, the advantage is cheap, the disadvantage is that the right and left eye degree can only be the same, the work is relatively common.If the usual degree difference between friends will have a certain amount of improper wear.

Matters needing attention

The degree ranges from 200 degrees to 1000 degrees (every 50 degrees is a unit, low choice). If there is astigmatism, it is recommended to convert the degree of astigmatism to myopia for selection, such as 500 degrees of myopia plus 100 degrees of astigmatism, 550 degrees of myopia can be selected to replace, which is the same principle as the choice of contact lenses.
