Best Contact Lens

Contemporary contact lenses are comfortable, long-lasting (unless by design, as in disposables) and very safe. Yet, there are some risks and limitations in wearing them and knowing what those are can help you choose the type that's best for you. Of course, any such decision should be made in consultation with your eye care professional.

Since 1986 many have opted for Rigid Gas Permeable contact lenses. Modern designs allow for up to five times more oxygen diffusion through the plastic than those of the past. That feature is important in minimizing the odds of corneal infection. The less oxygen that makes it to the eye, the higher the odds of an infection.

On the downside, RGP lenses are a little less flexible than other types, making them less comfortable for some. But, they may be better for correcting astigmatism as a result. They also can last up to 2-3 years, which is longer than typical soft contact lenses.

Many will want some type of soft lens, made from special hydrophilic plastic polymers that provide a lens that is flexible and therefore more comfortable. Current manufacturing techniques make possible a lens that doesn't suffer from a high likelihood of tearing, as did those in previous decades, but they do require more frequent replacement. Soft lenses also stay in place extremely well and require a shorter adjustment period.

Yet, for many, a hard lens is still the only option. While often less comfortable, and even though they raise the odds of scarring or infection slightly, their inflexibility is important. The eyes of some patients simply require the rigidity of this type and they prefer not to fall back on glasses. Those with certain types of astigmatism may not be able to wear soft lenses and require these instead.

Beyond those categories there are still several options for the Best Contact Lens.
