The biggest concern with any contact lens is the amount of oxygen that reaches the surface of your eyes. Older lens materials may not allow an adequate amount of oxygen to the surface of your eyes leading to discomfort especially at the end of the day. The lens materials that our doctors recommend allow more oxygen to the eyes resulting in greater end of the day comfort and health.
Modern contact lenses are made of the latest in materials technology to provide the healthiest environment for your eyes. Often time patients will remain in the same lens for many years and are not given the opportunity to try better, healthier lenses. Our doctors do not necessarily subscribe to this approach. Labs are frequently developing better, healthier, and more comfortable lenses and you (the patient) will not know if there is something better available until you try it on. Our doctors hope to offer you the best in new fitting techniques, materials, and lens designs to increase your comfort and wear time.
Several different types of contact lenses exist on the market. One lens type is the Gas Permeable (GP) lens. GP lenses offer the best visual clarity and the most oxygen of any contact lens and are custom designed for your eyes. The second type of lens is the Soft Contact Lens (SCL). This lens is more commonly worn by the general population, provides adequate vision, and improving oxygen transmission. SCL’s are disposable lenses discarded daily, weekly, biweekly, or monthly depending on lens type. GP lenses, on the other hand, last for 12-18 months depending on the amount of protein and lipid deposits and how well they are maintained. To receive a prescription for contact lenses a separate fitting examination is required that will measure the shape of your cornea to determine the appropriate lens. The specific demands of your prescription and the type of lens determine the complexity of the examination. For example, GP lenses are custom designed for your eyes thus demand more precise measurements of the eye’s surface compared to SCL’s. To assist our doctors in designing the GP lens, we employ the use of a corneal topographer which generates an image of the corneal surface. Our doctors then run computer simulations to predict how the lens will fit on your eye resulting in a more accurate lens fit and fewer return trips to the office.
