Leonardo da Vinci came up with the idea for contact lenses more than 500 years ago, and they became a reality during the 1880s. However, they weren't practical for regular use until the mid-20th century, with the invention of rigid corneal and gas-permeable lenses. Today, they are extremely popular as alternatives to eyeglasses. If you are considering contacts, you may have questions about them. Below are answers to some of the most common.

Commonly Asked Questions About Contact Lenses

What kinds are available?

Soft contacts are flexible and allow oxygen to pass through them. They are extremely comfortable and offer good vision. Rigid gas permeable (RGP) lenses are more durable and can offer better vision correction but are not as comfortable and take longer to get used to.

Extended-wear lenses are soft and can be potentially be worn for six to 30 days without eye damage, while daily disposable lenses are used only once before they are tossed out and replaced.

Orthokeratology lenses are worn over night and gently reshape the surface of the eye.  These lenses are removed in the morning and then are able to see clearly without wearing any contacts or glasses.

How long does it take to get used to contact lenses?

It depends on the type of lens. Soft contacts, including extended wear and disposable types, normally feel comfortable within minutes to a few days. It may take wearers a week or longer to get used to the harder RGP type. While it’s rare, some people never get used to wearing contacts.
