RGP lenses may be the best choice when the cornea has enough astigmatism (is shaped like an egg instead of an orange) that a soft will not provide sharp vision. They may also be preferable when a person has allergies or tends to form protein deposits on his or her contacts.


Soft Contact Lenses:

Most of people are wearer’s these lens. These are feel like relaxed and come in many types, depending on how you want to wear them. These are stay in place better and easier to adjust to than hard contact lenses. The flexible plastic is combined with water to allow oxygen to pass through the contact lens to the cornea. This increases comfort and maintains eye health. Soft contact lenses can correct nearsightedness (myopia), farsightedness (hyperopia), blurred vision (astigmatism), and age-related loss of close-up vision (presbyopia).

Soft contact lens have their drawbacks too, including a higher rate of infection and less durability than gas permeable contacts. They can also be more costly than hard contact lens since they may need more normal replacements.
