People with vision abnormalities often consider using contact lenses or laser eye surgery instead of eyeglasses. There are several facts to keep in mind about these methods of vision correction when making a decision between them.
Function
A contact lens corrects vision by changing the way light enters the eye. Laser eye surgery reshapes the cornea, reducing or eliminating the need for corrective lenses.
Types
Contact lenses come in several varieties, including soft contact lenses, extended-wear lenses and disposable lenses. The two main types of laser eye surgery are Photorefractive Keratectomy (PRK) and Laser-Assisted in situ Keratomileusis (LASIK), according to All About Vision.
Benefits
Contact lenses are a less-invasive option than laser eye surgery. The surgery is permanent and more comfortable than contacts after the initial recovery period has passed.
Warnings
According to the Food and Drug Administration, contact lenses can cause eye irritation or infection, especially if worn overnight. Laser eye surgery can cause eye dryness, corneal infection and halos around lights, especially at night.
Considerations
Certain health conditions might prevent a patient from having laser eye surgery. These include pregnancy, diabetes, lupus, glaucoma and cataracts.
