Soft contact lenses: first introduced over 30 years ago, are made from flexible, water-absorbent plastics. These contacts are anywhere from 30 to 80 percent water. Some soft lenses are designed to be thrown away daily, weekly, or every other week depending on your eye care professional’s instructions.

Fewer than 0.5 percent of lens wearers own them. Two types of contacts are fitted today – soft and rigid gas permeable, also known as RGPs. RGP lenses are made of special, firmer plastics that are suited for the passage of oxygen and other gases. These lenses are very durable and typically last longer than soft lenses. RGP lenses offer crisp vision and are often preferred by people with high degrees of astigmatism. While they make take a little longer to get used to, regular wearers find them to be comfortable and the visual acuity outstanding.

BIFOCAL CONTACT LENS – BOOMERS BATTLING BIFOCALS
A bifocal contact lens may be an option for you if you are on the far side of 40. Should you find that reading the phone book or newspaper is suddenly a chore, welcome to middle age, and presbyopia.
Presbyopia, the farsightedness that is inevitable with aging, is caused by the gradual hardening of the lens of the eye. It becomes less able to change shape, preventing us from focusing on close objects. Most people become aware of deteriorating lose vision in their mid-40s.
Many people turn to inexpensive reading glasses, but it’s important to have regular eye exams. Prescription lenses and bifocals allow a close-up correction giving the best possible vision for both close and far. If you are bothered by the telltale line that marks the bifocal, you may opt for bifocal contact lens.
Should your doctor decide that these are not an option, another increasingly popular alternative is called monovision. You wear a contact with a close-up correction in one eye and if necessary, a contact for distance correction in the other. Your brain gradually learns to adapt, and you see reasonably well thought out your range of vision.
The close-up contact generally goes in the non-dominant eye. Most people adapt to this type of lens correction in a week or 10 days even if they have never worn contacts before. Even people with astigmatism can be successful with monovision, often using rigid gas-permeable contacts instead of soft contacts for more reliable correction.
While true bifocal contact lenses are available, most people adapt to them less successfully than to monovision. Bifocal contacts are difficult to fit, and they don’t work for everyone. However, the latest disposable bifocal contact lenses from Acuvue have been very successful.0
