The other term for a gas permeable contact lens is rigid gas permeable contact (RGP) or oxygen permeable contact lens. Hard contact lenses are of the function as a soft contact lens. RGPs were introduced in the early 70s by way of silicone rather than polymers. Since the eyes need oxygen, this is a better fit than PMMA because this polycarbon does not allow oxygen to pass through. Silicone on the other hand is oxygen permeable, resulting in greater comfort and better eye health.

Gas permeable contact lens takes time to adjust to as compared to soft contact lens. The benefits however outweigh the consequences. One benefit is gas permeable contact lens retains its shape when one blinks. . They are extremely durable. A gas permeable contact lens is tougher than a soft contact lens because it only breaks when someone steps over it while the latter tears easily. Additionally, gas permeable contact lens is they are made of materials that doesn’t contain water so proteins and lipids that comes from tears will not accumulate on the lenses. The odds of suffering from eye irritations, infections are very low compared to the soft contact lens. Another excellent benefit of using a gas permeable contact lens is that it permits oxygen to go through the cornea. This prevents acute eye complications like inflammation of the cornea.

People with different afflictions prefer using gas permeable contact lenses. These people commonly suffer from astigmatism, presbyopia, or keratoconus. A person suffering from astigmatism might opt for this because it provides a desirable acuity. Conversely, people affected with presbyopia prefer them these lenses because of numerous and multi-focal designs. Those with keratoconus use gas permeable contacts because it prevents extreme visual distortion. Fore extreme conditions of dryness, gas permeable contact lens is very appropriate because the primary user blink less. Gas permeable contact lenses are also being utilized by people who use the computer often.

Gas permeable contact lens requires more care since they last longer than soft contact lens. Before deciding what type of lens to wear, always take time to consult a physician to determine if a gas permeable contact is the right contact lens for your condition.
