Contact Lenses

How do contact lenses work?

If you have a refractive error, an abnormality in the shape of your cornea or the lenses in your eyes doesn’t focus light onto the correct spot on your retina. Contact lenses, like eyeglasses, change the angle of light as it enters your eye to correct the focal point and provide clear vision.
Contact lenses are thinner than eyeglass lenses because they rest on your eye instead of approximately a half inch away. This means that the optic zone is smaller, only about the size of your pupil, to provide clear vision, while in glasses, the entire lens has to correct your vision.

What are the benefits of contact lenses?

Contact lenses provide a range of benefits. For example, they offer a full field of clear vision, and you may find that they provide more natural sight than glasses. They also don’t get in the way of any physical activities and won’t fog up when you go inside on a cold day.
Many patients also prefer the way they look in contact lenses instead of glasses.

Description & Process

Soft lenses

Soft contact lenses are available in several varieties. You may choose daily wear that you have to take out at night or extended wear that you can leave in for up to seven days. You may also select disposable daily wear lenses that are good for a day, a week, two weeks, or even a month. Soft contact lenses are also available in tints to change the color of your eyes.

Gas permeable lenses

Gas permeable lenses are made of rigid plastic and are often referred to as hard contact lenses. They’re smaller in diameter than soft lenses and provide sharper vision, although some patients find them difficult to get used to wearing.

Toric lenses

Toric lenses correct astigmatism. They’re slightly weighted to control how the lenses rest on your eye as astigmatism is due to the abnormal curve of your cornea. They’re made of soft plastic and have tiny marks that show you the position to put the lenses into your eyes.


Multifocal lenses incorporate different prescription strengths. For example, many patients develop presbyopia after the age of 40, which makes it harder for you to focus on close-up objects. If you wear glasses, you might choose bifocals or multifocals, but you can also get contact lenses that correct your vision the same way.
