Contact lens prescriptions should come from a qualified eye care specialist. This is especially true with the contact lenses that are used either corrective or therapeutic. Stores would require a prescription before they sell a pair.
Here are the things that you have to look for in a prescription to determine its validity:
- The patient’s name should appear in it. This important detail would prove that the person who has the prescription has gone through the necessary procedures essential to determine the right pair of contacts he or she has to get.
- The date of the examination. The examination date has to be current. This ensures that the prescription is freshly made and that the patient is recently examined. This is very important in therapeutic contact lenses.
- The issue date and the date of expiration of the prescription. These two sets of dates are equally important as the examination date. This solely determines if the prescription is still usable.
Contact lenses are extremely popular world over as fashion statements and to improve eye sight. The lens when wearing a contact lens is placed right over the cornea. The cornea is defined as the clear front portion of the eye where light rays are bent and focusing occurs. The cornea has no blood supply and derives oxygen directly from the air itself.
According to ophthalmologists and other doctors who specialize in diseases of the eyes, those who wear contact lenses must protect the cornea from problems like the abnormal growth of blood vessels and irritations caused by lack of oxygen and chemicals.
Contact lens wearers must be aware of safety procedures and be sure to observe them:
- Avoid the temptation to wear colored contact lenses. Studies have shown that colored lenses worn in the eyes reduce the amount of oxygen that reaches the cornea. The FDA has reported that decorative colored contact lenses can cause: conjunctivitis, corneal edema, allergic reactions, corneal abrasions, reduction in vision, sensitivity such as inability to contrast and so on.
People who need corrective lenses for better vision prefer contact lenses to glasses for reasons more than one. Besides the apparent appearance, glasses may be uncomfortable on the face, be heavy on the ears and nose and may have glare problems. This drawback can be overcome by using contact lenses, which are almost invisible on the eyes to others.
Initially, contact lenses were made of glasses and were rigid and uncomfortable. But soon they were replaced by a polymer based product which made them a little comfortable. But this type of contact lens too had a hiccup, the oxygen flow to the cornea was restricted and this caused problems to the eyes of those who wore contact lenses for a prolonged time.
If you’ve always wanted to change your eye color, color contact lenses can provide baby blues, gorgeous greens, heavenly hazels — even various patterns and designs. Contact lens sales are regulated by the FDA (Food and Drug Administration) and the FTC (Federal Trade Commission.) In the U.S. contact lens marketplace, 82 percent wear soft lenses, 16 percent wear rigid gas-permeable and only 2 percent wear hard.
You’ll want to take simple precautions to make any lens purchase safe and effective. With a contact lens prescription in hand, it’s possible to buy your contact lenses from stores, the Internet, over the phone, or by mail.
If you live an active lifestyle, NIGHT & DAY breathable lenses will allow you 30 hours of continuous wear. Disposable lenses don’t come with instructions for cleaning and disinfecting, while those labeled specifically for planned replacement do. Contact lenses are often more complex than they appear to be.
Are you about to venture into the world of wearing contacts? Many people in need of corrective lenses choose to wear contact lenses because of the comfort and an aversion to looking awful with glasses. Glasses slip down your nose, weight on your ears and nose, and have glare problems with light. You also have to have special lenses or an extra pair to keep the sun from blinding you when wearing glasses. A contact lens allows you to get rid of this paraphernalia and simply have corrected vision. Most individuals won’t even realize you are wearing a contact lens because they are virtually impossible to see in your eye.
