Contact lenses are more than just a way to avoid wearing glasses—they are a hardworking prosthetic that help correct a range of vision problems. Learn more about these conditions below.
Myopia is a condition in which the eye focuses light from a point source in front of the retina instead of on the retina. The nearsighted constitute the majority of contact lens wearers. With higher prescriptions, the ability to have superior side vision and truer image size is a definite asset for lens wearers.
Hyperopia is a condition in which the eye focuses light from a point source behind the retina instead of on the retina. The advantages of contact lenses for the farsighted are similar to those of the nearsighted.
Presbyopia is a normal condition in which the accommodative ability of the natural lens of the eye is reduced in middle age, necessitating a secondary lens for near vision. There are a number of methods that may be utilized to aid the bifocal wearer, and we will discuss those with you should you require a bifocal solution.
Astigmatism is a condition in which waves of light are not focused at one point on the retina, but at two separate lines of focal points. This condition results from an irregularity in the curvature of one of the refractive surfaces of the eye, usually the cornea. Hard and gas-permeable contact lenses can correct this irregularity, artificially correcting the flawed curvature. Soft toric lenses also can help correct astigmatism, depending on the severity.
Keratoconus is a relatively rare condition in which the cornea becomes progressively cone-shaped. Owing to the nature of this condition, it cannot be satisfactorily corrected with conventional eye glasses. In this case, contact lenses provide a far superior solution, as they replace an irregular corneal surface with an artificial regular surface. It must be noted that, similar to high astigmatism, soft contact lenses will not aid this condition.
