The most traditional and classic way of vision correction is to wear eyeglasses. Eyeglasses have existed since 13^th century, and today’s eyeglasses are not only the device of vision correction, but also a piece of face jewelry enhancing wearers’ fashion expression. From the medical point of view, as this kind of vision correction has no physical contact between the glasses and the eyeballs, eyeglasses impose the least possibility if harmful effects like infections and other severe side effects.

Wearing contact lenses is the second choice to obtain vision correction. The advantages of contact lenses are apparent by liberating people from the encumbrances of physical glasses perching on the nose, disturbing a lot of activities of human being. The disadvantages are also remarkable as extended use of contact lenses, especially the over night wearing, will cause serious infection and even blindness.

The third choice belongs to the laser eye surgery, also called LASIK. LASIK permanently offers vision correction after a successful surgery, minimizing people’s dependency on eye glasses and contact lenses. The mechanism of LASIK is that the computer-controlled laser cuts the cornea and vaporizes some part of the middle layer of the cornea to achieve the once-and-for-all vision correction. Though LASIK has been proven to be the easy surgery of only a couple of minutes with very high success rate, there are still a lot of drawbacks like halo, haze, double vision and even blindness.

The fourth alternate is to gain vision correction in the natural way by eye exercises. These eye exercises have existed for more than a century, but the final causality still lacks strong and supportive evidence.

All the above four options of vision correction have their pros and cons, all you need to do is to always consult your doctor and choose one that most suits your personal needs of vision correction.

Vision correction has undergone a long way of approximately 100 years. Scientists have developed several ways to correction vision problems affecting a large group in the world. Three methods are most widely used, namely eyeglasses, contact lenses and laser eye surgery.

Eyeglasses actually have two functions. Of course, the first one is vision correction, which is the initial concept in eyeglass inventors. But in fact, corrective eyeglasses do not really correct one’s vision. These devices only offer a compromise by altering the light reaching the eyes. Another function of eyeglasses as external devices is offering special look for a wearer. Eyeglass wearers can get a slightly or considerably different look. Eyeglasses for vision correction or appearance change are convenient. They are easy to insert and remove and very little care is required.

A second option for vision correction is contact lenses, which fit directly over the eyes. Contact lenses perform vision correction based on the same principle as eyeglasses. They only refocus the light entering the eyes as well. In most cases, contact lenses do not change the wearer’s natural appearance. Unlike eyeglasses, contact lenses require frequent lens care, such as sterilization, cleaning, disinfecting and so on. In general, contact lenses are more costly than eyeglasses, because they need more frequent replacement.

The third solution to refractive errors is laser eye surgery that comes in various types including the most popular one LASIK. Laser eye surgery aims to correct vision problems permanently. In any way, laser eye surgery carries certain risks, although at a very low level. Laser eye surgeries are more expensive than eyeglasses and contact lenses. But their incomparable visual benefits have attracted a large number of patients.
