Ridgid Gas Permeable Contact Lenses May Be A Better Option
Have you been disappointed with the vision you get with soft contact lenses? Do you have astigmatism that does not seem to be corrected well with soft toric contact lenses? A possible option for you may be gas permeable contact lenses. Why Is This Option Possibly Good For You?
Gas permeable lenses are made of rigid materials as opposed to soft materials. As such, the rigid material gives the cornea a spherical shape and helps mask or correct small to moderate amounts of astigmatism (less than 2 diopters) without having to use a toric design. These lenses can also help people over 40 who have difficulty reading since this material can be used for both bifocal contact lenses and multifocal contact lenses. What Are Some Of The Advantages Of These Lenses?
Rigid gas permeable lenses have many advantages which make them a viable option to improve your vision: Is The Eye Exam Going To Cost You More Money?
The art of fitting gas permeable contact lenses demands a considerable degree of skill and knowledge and so you can expect to pay an eye practitioner more for this type of exam. These lenses are in a sense custom made to fit your eye and such information as the curvature of your cornea, your pupil diameter, your cornea diameter, and your prescription are used to figure out specific parameters to these lenses. They are typically tinted in either blue or green although they do not change the color of your eyes. Usually, the right lens has a black dot on the edge to distinguish it from the left lens. |
