Effects of Wearing Contacts During Sleep | Uratex Blog

A contact lens is a medical instrument that corrects eye vision; it serves as a substitute to eyeglasses. Their design depends on the different magnification requirements of various eyes, while their appearance simply depends on personal preferences.  Some people even personalize their contact lenses that would accentuate their personalities and/or hobbies.  (Did you know that there are contact lenses that look like a soccer ball?) But, be it for style or for medical purposes, people should be aware that contact lenses, when not used properly, could cause damage our eyes.

There are two types of contact lenses: Conventional and Disposable. Conventional contacts are designed for long-term use. Its life-span should be between one to six months. Disposable contacts, as its name imply, are contacts manufactured to last for only two weeks of use, at the most. Subcategories include hard lenses, soft lenses, extended-wear lenses, rigid gas permeable lenses, and refractive lenses. Among these six subtypes, only the extended-wear and refractive lenses are the only ones that can be safely worn overnight. Because they are specially designed to cure extensive eye problems, one should receive the recommendation of an ophthalmologist or optometrist recommendation before he or she considers buying a pair of either one of them.
