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.

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.

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.

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.
