Vision problems beyond contact lenses

Most people with vision problems will consult a qualified optometrist about potential options of vision correction. Currently, there are various ways to treat visual issues, from special eyeglasses to laser surgery. With proper treatment, these options can always restore most or all of the vision. Contact lenses are just one of the solutions to common vision problems such as nearsightedness, farsightedness and astigmatism. However, contact lenses can not correct certain vision problems.

Many contact lens wearers may have experienced dry eye. In particular, extreme dry eye can cause eye soreness and a great deal of discomfort in contact wearers. Some people with very dry eyes or have allergies may frequently rub or scratch their eyes, which leads to eye damage and even eye infections in some instances. What's worse, eye rubbing can degrade the surface of the cornea. In this case, contacts wearing may become impossible for ever, even though in the help of frequent lubrication drops. Eye doctors should always have a second thought before prescribing contact lenses to patients with serious dry eyes or allergies.

Conjunctivitis is another type of vision impairment, which is a malfunction of the glands that secret the fluids of the eyes. In consequence, protein built-up may occur if a person with conjunctivitis wears contact lenses, especially extended contacts such as 30 day soft variety. In detail, malfunctioning glands will produce fluids containing excessive proteins, which may cause congestion and infection in the capillaries. In other words, people with conjunctivitis are prone to eye infections if they decide to take contact lenses. Untreated infection may cause permanent vision problems as serious as blindness. Moreover, conjunctivitis is sometimes associated with a burning, itching redness in the eyes.

Contact lenses can do nothing with partially or fully blindness in one or both eyes. As a cellular issue and a breakdown of the actual eye tissue, blindness may result from congenital reasons, illness or eye injury. This condition of blindness can never benefit from contact lenses in vision improvement. The only benefit of contacts for a blind eye may be cosmetic.

Before choosing contact lenses, patients are required to consult with an eye doctor. In addition, always choose contact lenses in high quality to avoid any side effects or complications.
