Contact Lenses

Contact Lenses at Sumner Vision

Being able to see clearly greatly improves your quality of life. When your vision is properly corrected, you can see better to drive, watch a movie, participate in meetings and perform many other activities. Contact lenses allow you to enjoy the benefits of clear vision without having to wear prescription eyeglasses and can simplify vision correction.

Why Contact Lenses

Contact lenses offer numerous benefits for those who are in need of vision correction. Unlike eyeglasses, contact lenses will not fog up due to changes in temperature, and they will not become smudged or smeared during the day. With contact lenses, you can wear sunglasses, protective eyewear and 3D movie glasses more comfortably, and your appearance won't be changed by wearing the lenses. In addition, contact lenses fully cover the eye, so that your vision is enhanced no matter which direction you look - a benefit that eyeglasses cannot provide.


Varieties of Contact Lenses

Contact lenses come in a wide variety of types, ensuring that there is something for everyone. Lenses come in two main varieties: daily wear or vial contacts that you continue to use day-in and day-out and disposable lenses that you wear for a specific period of time before throwing them away and using a new pair. There are a number of specialty types of contacts that are ideal for certain individuals. Color lenses change the color of the eyes while correcting vision, while toric lenses are made for people with an eye condition called astigmatism, which affects the way the eye focuses. Multifocal lenses improve both near and distant vision and are suitable for individuals who require bifocal eyeglasses.

Getting the Right Type

Before ordering contact lenses, you'll need to visit an optometrist to have an eye exam. The optometrist will determine what strength of lenses is ideal for your needs and what size lenses will best fit your eyes. He or she will also discuss your lifestyle and daily habits with you to help determine which variety of contact lenses will be the most convenient for you to use and will be the safest option for your eyes. Then, you will be provided with a prescription that states what brand, type, strength and size you should purchase.

How do contact lenses work?

If you have perfect vision, light focuses on the light-sensing structure in your eye called the retina in exactly the right location. Contact lenses improve vision in near-sighted and far-sighted people by altering how light focuses on the retina when it passes through the eye. The lenses are kept in place by the natural tears that lubricate your eyes.


How long do contacts last?

Some daily-wear contacts can typically last for up to one year when cared for properly. Disposable contacts are worn for shorter lengths of time, such as one day, one week or one month. The packaging for disposable contact lenses will have an expiration date printed on them, and the lenses should be used before that date for best results.


When were contact lenses invented?

Artist and inventor Leonardo da Vinci produced sketches for a very basic type of contact lens in 1508, but the first wearable contact lenses weren't produced until the late 19th century. F.E. Muller is often credited with creating the first glass lenses in 1887. Others credit Adolf E. Fick and Edouard Kalt for creating the first glass contact lenses in 1888. The first glass and plastic lenses were invented by William Feinbloom in 1936.


How long can you wear contacts?

The length of time that you can safely wear contacts depends on their type. Most lenses should be removed prior to bed; however, extended-wear contacts can be worn continuously for a set length of time, usually for up to 30 days. Your eye doctor can provide you with specific advice regarding how long you can wear your lenses on a daily basis.


How old do you have to be to wear contacts?

There is no specific minimum age requirement for wearing contact lenses. As long as a child or teen can handle and care for contacts appropriately and a doctor prescribes the lenses, they can be worn safely. Most eye doctors recommend that kids start wearing contacts between 8 and 11 years of age.
