Things You Need To Know About Wearing Eyeglasses
First, before choose eyeglasses, people should go to the regular eye hospital to examine their vision in order to get an accurate prescription. And people should examine their vision in person. Be sure not to use the former prescription to buy prescription glasses. If people wear a pair of unsuitable eyeglasses, their vision will further worsen. The general principle of choose eyeglasses is that look clearly and feel comfortable. Namely, not only see thighs clearly with both eyes, but also see clearly with each eye; and it is suitable for people that there is no feeling of dizziness or space shakes.
Second, the principle of choosing myopic glasses is to achieve the standard that correcting vision is up to the lowest normal vision strength. The strength of myopic glasses prefers to lower the real strength rather than higher. For lightly shortsighted people, they can wear myopia glasses only when work or study, and they can take off glasses when they do not work.
Actually, it is not good for lightly shortsighted people to always wear a pair of prescription glasses,but the moderate shortsighted people may wear glasses no matter they work or rest. For astigmatism people, they should match the glasses both for myopia and the astigmatic. Commonly, if astigmatism strength is over 300, the lens strength can be suitably reduced under the condition of not affecting vision correction. Moreover the astigmatism people must wear glasses all the time, no matter how many their strength is.
Third, when chooses frame, attention should be paid that the distance of lens optical center must be consistent with the pupil spacing. Moreover, on one hand, frame should have a slightly downward inclines about 5 degrees, otherwise glasses are easy to lead to eye discomfort or eye fuzzy. On the other hand, there are two points for the choice of lens material. The glass lens is at a low price and the weight is heavy. Such lens is easy to break off but is durable. The resin lens has a high price and a lightweight. It is difficulty to brittle but easy to scratch. The latter kind is especially suitable to the young people. However, no matter resin lens or glass lens, wearers need to reexamine their vision a half year or one year, enabling eyeglasses to suit their present vision.
In addition, it is suggested that young people would better not wear the contact lenses, RGP (rigid cornea contact glasses), or the eyelet glasses. The reasons are that the contact lenses are only suitable for people whose refraction differences is above 300 degrees; the RGP glasses are easy to cause cornea infect if wear for a long time; the eyelet glasses limit the field of vision, and there is no help for myopia to wear a pair of eyelet glasses for a long time.
