Patients with errors of refraction like nearsightedness, farsightedness, and astigmatism need glasses or contact lenses for correction. At Chevy Chase Eyecare, we can help with regular and specialty contact lenses in Chevy Chase, MD. If you’re not comfortable with glasses or looking for a change, getting regular and specialty contact lenses near you would be a great solution.
There are different types of lenses that you might find confusing. You may have heard of soft lenses, toric lenses, colored contact lenses, gas permeable lenses, and orthokeratology. We’ll help you identify the differences between them and tell you what will work best for you.
Soft lenses are the most common. They’re made of modified plastic that makes them soft and flexible. These contacts let oxygen pass through to the cornea. Silicone hydrogels can also be used to manufacture soft lenses to make them more permeable to oxygen. Soft lenses are very comfortable and easy to get used to. If you don’t take care of them, however, they’re more likely to tear than rigid lenses.
Rigid gas permeable lenses are more durable. You won’t need to change them as often as soft lenses, so they’re cheaper in the long run. Unfortunately, they’re not very comfortable to wear, especially for the first few weeks.
Toric lenses are those that have two powers. Patients with only nearsightedness or farsightedness can get regular contact lenses in Chevy Chase, MD. Those with astigmatism, however, will need toric lenses to correct for the error in distance vision and astigmatism.
Orthokeratology is the use of rigid gas permeable lenses to alter the shape of the cornea. This helps temporarily fix the error of refraction. Orthokeratology lenses are usually worn overnight. You’ll take them off during the day, but your vision will be improved due to the changes that happened while you slept. If you stop wearing these lenses, however, the effect will fade.
Coloured contact lenses are cosmetic. If you want to give your iris a different color, colored contact lenses in Chevy Chase, MD, will make this possible. The lenses themselves are colored and won’t change anything in your eyes.
