Contact Lens Designs
While contact lenses are similar to glasses in correcting nearsightedness, farsightedness and astigmatism, they can offer a complete range of unhindered vision, making them suitable for sports and certain careers. They are available in various designs, including: Spherical contact lenses that can correct myopia (nearsightedness) or hyperopia (farsightedness), toric contact lenses, which can correct astigmatism, bifocal contact lenses that can help correct presbyopia, with separate zones for near and far vision.
Useful Tips for Using Contact Lenses
Here are a few tips to help you get the most out of your contact lenses: replace them regularly to lessen the risk of eye infections caused by contaminated lenses and lens deposits. If you use daily wear lenses, take them out and clean them every night. You can wear extended wear lenses both during the day and overnight. Don't wear them for over 30 nights in a row. Discard daily disposable lenses after wearing them for a single day; bi-weekly disposable lenses after wearing them consecutively for 2 weeks; and monthly disposable lenses after you've worn them successively for a month.
