Contacts Lens FAQ

Although the standard "hard lens" introduced in the 1950's are still around, newer materials developed have made these lenses virtually obsolete. Two types of contacts are fit today, Soft and Rigid gas permeable (RGP) Soft contact lenses, first introduced 30 years ago, are made of flexible, water-absorbent plastics. In fact, these contacts are anywhere from 38% water and up. Some soft lenses are designed to be thrown away daily, weekly, bi-weekly, monthly or quarterly, depending on your eye care professional's instructions. Others can be used for up to I year. Many people enjoy the comfort of soft contact lenses. They're easy to insert, and fit securely on the eye. RGP lenses are made of special, firmer plastics suited for the transmission of oxygen and other gasses necessary to maintain eye health. These lenses are very durable and typically last longer than soft lenses, sometimes more than 2 years. RGP lenses offer crisper vision than soft and are often preferred by people with high myopia, astigmatism or other hard-to-fit contact lens patient's. While they may take a little longer to get used to, regular wearers find them comfortable and the visual acuity outstanding.

Many doctors prescribe contact lenses to clear user's far vision. Patients over 4O may notice a progressive decrease in the ability to view near images, like medicine bottle labels or small print, through their distance contact lenses. This may appear suddenly and leave the patient wondering what is wrong with their lenses. The condition that causes this is called Presbyopie and affects everyone over 40 years of age. A contact lens fitting process called Monovision, where the doctor underprecscribes the non-dominant eye is the most common way of getting.around the effects of Presbyopiapia in contact lens wearers.In the past few years, great advances have been made !n contact lens technology allowing the user to "get their young eyes back" -- these technologies include soft and RGP bifocal contact lenses and progressive contact lenses. People who have tried these technologies unsuccessfully in the past may now find them more accommodating, science has greatly improved the functionality of the lens. The most effective "multifocal" contact lens is a RGP aspheric design. An eye doctor experienced in fitting these modalities should -evaluate your eye to see if you are a candidate for a multifocal contact lens option. In almost all multifocal contact lenses, night vision can be slightly decreased. This can be remedied with a simple pair of night-driving glasses you put on over the contacts and leave on the visor of your car for such situations. Fine pint may be very clear and readable, but for extended near work such as reading a book or an entire newspaper, a small near prescription over the contact may help prevent fatigue.

Daily wear contact lenses are designated to be removed each day for cleaning and taken out before closing your eyes for extended period of time. Extended wear lenses can be worn continuously for up to 7 to 30 days, depending on the recommendations of the Food and Drug Administration. Extended wear lenses can also be removed each day for cleaning and slept in occasionally when special circumstances arise. Eye care professionals consider many variables in deciding between daily wear and extended wear lenses for each patient's needs. The latest technology in extended wear are the Silicone Hydrogel Soft Lenses. These lenses are the safest lenses to date for extended wear. While the risks of extended wear still exist in Silicone Hydragel, they have demonstrated lower levels of complications than previous technologies. Be sure you visit an experienced eye doctor to be fitted with Silicone Hydrogel. Your doctor should recommend a quarterly eye check up to ensure the lenses are compatible for your eyes health and well being.
