Contact lenses are small plastic discs that correct visual problems much like glasses do. In 1837, Swiss physician Dr. Fick and optician Edouard Kalt developed the first glass contact lens. Today, the contact lens can change your eye color as well as correct your vision.
Types
Contact lens types include soft, rigid gas permeable (RGP), extended wear, and disposable. Soft contact lenses are the most commonly used and most comfortable contact lens available. Rigid gas permeable lenses can accumulate debris and easily slip off the eye. Extended wear lenses can be worn up to seven days without removal. Disposable lenses require little to no cleaning.
Risks
According to the Food and Drug Administration, the risks for contact lens use include eye discomfort, increased tearing, drainage, swelling, pain, light sensitivity and a burning, itchy or gritty feeling. Serious side effects include corneal ulcers and blindness.
Get Contact Lenses
To get contact lenses, you must go to an ophthalmologist (MD), optometrist (OD), or licensed optician. He or she will examine your eyes and provide you with a prescription and free trial.
Warnings
You should not sleep in contact lenses or share them with friends, as this increases your chances of getting an eye infection. The Food and Drug Administration also recommends against swimming in contacts. If you want to swim in contacts, check with your eye doctor first.
Population
Contact lenses are available for people of all ages. Most people begin wearing contact lenses shortly before their teenage years. They are also popular among college students and working professionals.
