The Difference Between Lenses
When you visit our optometrist in Las Vegas, there are some things to keep in mind about the different contact lenses.
Materials Your Optometrist May Recommend
There are five types of contact lenses available to you that are different based on the material used.
Soft Lenses: These are made from gel-like water plastic. The lenses are thin and pliable to conform to the front surface of the eye.
Silicone Hydrogel Lenses: These are a progressive type of soft contact lenses. These lenses are more porous and allow for more oxygen to get to the cornea. These are the most popular.
Gas Permeable Lenses: These are rigid contact lenses that are more porous than PMMA lenses and allow more oxygen to pass through. They are more comfortable than traditional hard lenses. These lenses can give sharper vision than soft lenses, especially for those who have astigmatism. It does take some time for the eyes to adjust but many people find these lenses comfortable.
Hybrid Contact Lenses: These lenses are designed to have the comfort of soft lenses and the clear optics of typical gas permeable lenses. Not many people wear these and they can be expensive and harder to fit.
PMMA Lenses: These are made from a transparent and rigid plastic material. These lenses have great optics but don’t give enough oxygen to the eye and can be hard to adapt to.
The Wearing Time of Contact Lenses
In the past, everyone who had contact lenses had to remove and clean them nightly. Now there are different types of lenses classified by the wearing time. These include daily wear and extended wear.
Contact Lens Designs
Soft contact lenses have different designs depending on their intended purpose.
The spherical lenses will have the same lens power through the entire lens to correct nearsightedness or farsightedness. Toric lenses have different powers in the meridians of the lenses to help with astigmatism. Multifocal lenses contain different power zones for far and near vision and some can also help with astigmatism. Cosmetic contact lenses include color contacts designed to intensify or change the eye color.
Deciding on Lenses at the Optometry Clinic
Your lenses must address the problem that makes you wear lenses in the first place. The lenses must fit your eye before you can consider your wish list for contact lenses, such as style or color. Visit our optometry clinic in Las Vegas to find the right lenses for your needs.
