Three common solutions to refractive errors
As people age, various changes in the body including the eyes will take place. Eyesight decline is quite common in old individuals and vision loss is also potential. Some old folks can not see small or far away things clearly, while some others are unable to perceive near objects. These are common vision problems such as nearsightedness, farsightedness and astigmatism. Fortunately, modern science has made various ways of vision correction available.
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.
