Bifocal contacts are a great option for people who need a different prescription for distance viewing than they do for reading and other close-up work. Just because you need bifocals, doesn’t mean you always need to wear glasses. Ask your eye doctor how you can try a multi-focal lens today.
Contact lenses are first and foremost a practical device. But there's no reason they can't also be a fashion statement, a way to alter your natural attributes to suit your fancy. A full range of colored contact lenses are available but almost all of them still give the ability to improve vision the way regular contact lenses do.
Daily disposable contact lenses represent the ultimate in convenience - wear them for a day and then throw them away. Dailies are the ideal contact lens for busy people who don’t have time to clean and care for their contacts.
Weekly disposable contact lenses are made to be used for 1 to 2 weeks and then thrown away. Weekly contacts are some of the most prescribed around including the #1 seller Acuvue Oasys, Biomedics 55, and O2 Optix.
Monthly disposable contact lenses are designed to be worn for 1 to 3 months, as directed by your doctor, and then thrown away. Popular monthly contacts include Proclear Compatibles, Purevision, Biofinity, Focus, and Air Optix Aqua.
Rigid Gas Permeable (RGP)
Contact lenses reduce the oxygen that contacts the eyes somewhat. In the past, that 'somewhat' was substantial. That's why rigid gas permeable (RGP) contact lenses were invented. RGP lenses allow several times more oxygen to diffuse through the lens itself than other types.
In the past contact lenses were able to easily correct nearsightedness or farsightedness, but nothing else. Correcting some forms of astigmatism still required wearing glasses. Toric contact lenses ultimately solved that problem.
