Although we pay attention to our vision problems in recent years, the number of people who suffer from myopia is still increasing. As a result, more and people are wearing prescription glasses. However, many people hold wrong opinion on prescription glasses. For example, a lot of people think that the prescription glasses are to cure the myopia. As a matter of fact, myopia can’t be cured by glasses. The prescription glasses are used to correct myopia. They are just the vision correction aids. If you want to recover good vision condition, doing eye operation can achieve it.

The so-called myopia, or shortsightedness is a refractive defect of the eye in which collimated light produces image focus in front of the retina when accommodation is relaxed. Or more simply, it is a condition of the eye where the light that comes in does not directly focus on the retina which is in the back of the eye. Because of this, the image that one sees is out of focus.

Eye care professionals most commonly correct myopia through the use of corrective lenses, such as glasses or contact lenses. It may also be corrected by refractive surgery, but this does have many risks and side effects. The corrective lenses have a negative optical power which compensates for the excessive positive diopters of the myopic eye.

From the current optical market, the framed glasses are composed of frames and lenses. To correct the vision problems depends on the lenses. There are several types of lenses including glass, resin, PC lenses. Different materials have different features and advantages. The contact lenses are quite hot in recent years for they relieve the burden of the nose and increase the sense of beauty.

No matter for the framed glasses or the contact lenses, it is necessary to have an overall and professional visual check before, that is to say, to know the vision condition carefully. What’s more, for those who wear framed glasses or the contact lenses, it is essential to pay enough attention to habit and eye health in daily life and sustain a good vision condition.
