Contact lenses have been in existence since the 1930s, but for many of those years they were heavy, hard, uncomfortable and only corrected a limited range of refractive errors. Today's contact lenses come in a broad spectrum of types, materials and usage options -- such a broad spectrum, in fact, that it can be hard to know where to start with these corrective lenses. But whether you are searching for your very first pair of contact lenses or you know exactly what works for your eyes and your lifestyle, you'll find your solution right here at University Vision Centre.
Corrective lenses of various sorts are prescribed to compensate for refractive errors that cause incoming light to focus at the wrong point inside the eye. If the cornea is too steep or the eyeball is elongated instead of spherical, you have myopia or nearsightedness; if the cornea is too flat, you end up with hyperopia or farsightedness. Astigmatism is a refractive error caused by unequal corneal contours. Presbyopia occurs in the middle-aged lens due to a progressive loss of focusing ability.
All of these conditions can easily be corrected by changing the path of light with corrective lenses. But if your active lifestyle or sense of style doesn't agree with eyeglasses, then contact lenses can correct your refractive error by refocusing incoming light right at the cornea.
Which Contact Lenses Are Right for You?
Contact lenses take many forms in this modern age and the type you select may depend on your personal preferences, lifestyle considerations, eye health and specific refractive error. Options include:
Soft contacts vs rigid gas permeable contacts - Soft contacts may be more comfortable and easier to get used to for some, and they come in disposable models that require minimal cleaning and maintenance. RGP contacts are specially designed to allow oxygen to pass through to the eye, permitting safe all-day wear; they can handle complex or severe refractive errors better than soft contacts can.
Duration of use - Single-wear disposable lenses can be great for very active people, while extended-wear lenses are an option for people who don't want to be removing and inserting their contacts every day.
Eye health/refractive error issues - Dry eyes require contact lenses that help the eyes retain as much moisture as possible. Presbyopia calls for multifocal lenses that give you distance vision, intermediate vision and near vision correction. If you have a deformation of the cornea called keratoconus, you may need to wear scleral or hybrid contacts. These contacts are large in size so they can sit on the white of the eye instead of the cornea.
