Daily and Monthly Disposable soft contact lenses
These are the most common type of contact lens and suit people with short and long sightedness, astigmatism, there are even multifocal contact lenses, for people who just wear reading glasses. They are comfortable, relatively cheap and provide great sight, perfect for you to have the best vision for life.
Originally soft contact lenses were made from a hydrogel material which had a very low oxygen permeability and thus didn’t breathe well on the eye. Today while Hydrogels are still used, MOST are made from a newer material called silicone hydrogel which delivers significantly more oxygen to the eye and as a result increases the comfort and wearability factor. They come in daily, two weekly and monthly use configurations. The most popular are daily disposables due to ease of use and lack of maintenance/cleaning required. Of significant popularity is the use of Multifocal lenses now available for those patients entering or requiring glasses for reading or both distance and reading what we call Presbyopic vision.
Presbyopic contact lens options include
Multifocal contact lenses vary in strength across the lens. Multifocal lenses supply light at different focusses to your eyes and your eyes and brain sort out which focus distance to concentrate on. This differs to bifocal or progressive spectacle lenses which vary in strength depending on where you look.
Monovision relies on wearing a contact lens that is clear for long distance in your dominant eye and a contact lens clear for near work in your other eye. It may sound a little strange, but this method works successfully in many people.
Combinations of contact lenses and glasses
Combinations of contact lenses and spectacles are often used to help out near work. This is especially the case if reading correction is only needed occasionally. Wearers of multifocal contact lenses can also be use 'over-readers' to enhance focus for fine tasks.
“Hard” or Rigid gas permeable lenses
Like soft lenses, hard lenses have evolved in material from the very hard HEMA to a combination of silicone and methacrylate to allow for a more comfortable experience. Hard lenses are not used regularly these days however they have their place in the ophthalmic world for special conditions like high Astigmatism and Keratoconus where glasses may not be the best solution.
Ortho-keratology is another use of hard lenses for temporarily reshaping the cornea to alleviate myopia for a short period of time.
Contact lenses are an excellent option for either full-time or part-time wear. They’re also great for
sports and hobbies.
