The contact lens world is constantly changing. The manufactures are always working on developing new materials and contacts to help you see clearer while promoting good eye health. It is important to know about the types of lenses available and how to use them safely.
Whether you already wear contact lenses or are considering them, our doctors and staff are here to help you find the perfect fit for you.
Types of Contacts
Soft contact lenses are the most popular choice for contact lens wearers. They’re comfortable and come in many versions depending on how you want to wear them. They are replaced on a daily, weekly or monthly basis.
Gas permeable (GP) contact lenses are more durable and resistant to deposit buildup. They may be the best choice when the cornea has enough astigmatism that a soft lens will not provide sharp vision, or when a person has eye allergies or tends to form protein deposits on his or her contacts.
Color contact lenses are contacts that change or enhance the appearance of your eye color and may also correct your vision. They are only available by prescription and should only be worn after an eye exam and fitting by a qualified eye care professional. Never wear color contact lenses without a prescription, as serious eye complications may occur without professional supervision. Serious eye health problems can occur as a result of sharing contact lenses.
Contact Lens Designs
Spherical lenses are basic contact lenses typically used to correct myopia and hyperopia. They bend light evenly in every direction.
Toric lenses help correct for astigmatism in combination with nearsightedness or farsightedness. They come in both soft and gas permeable varieties.
Multifocal lenses are designed to correct presbyopia in combination with nearsightedness and farsightedness. They come in both soft and gas permeable varieties.
Wearing Period & Replacement Schedule
Daily-wear lenses are removed nightly. Some daily wear lenses are worn once and thrown away. Other daily wear lenses are removed every night for cleaning and disinfection and replaced at the end of a longer replacement schedule.
Extended-wear lenses are worn overnight. Some extended wear lenses are only approved to wear overnight for up to a week before they must be removed for cleaning and disinfecting, and some extended wear lenses can be worn every night for up to a month.
Daily disposable contact lenses are worn for a day and then thrown away; there’s no need for solutions to clean, disinfect and store them. These are one of the safest and most trouble-free contact lens options, provided they’re worn only for a single use.
Bi-weekly/monthly replacement lenses are worn daily for up to a month and must be removed each night and cleaned, disinfected and stored using the contact lens solutions recommended by your eye care professional.
