Frequency 55 Toric Contact Lenses For Astigmatism Are An Increasingly Popular Choice

By David Long

Frequency 55 Toric contact lenses from Coopervision are an increasingly popular brand of toric lenses for astigmatism patients, offering superior comfort and visual acuity. You can wear and remove them every day, or optionally use them for up to 7 days of extended wear. They only need to be replaced with new lenses once a month.

Frequency 55 Toric lenses fix the odd shape of the cornea caused by astigmatism. Most people's corneas are shaped like a sphere, but the astigmatic cornea is shaped more like a football. This odd shape causes blurry vision because light rays scatter rather than focus sharply on the retina where they belong.

Frequency 55 Toric lenses correct your astigmatism, once they are securely in place, by acting as a refracting medium that re-focuses light rays properly on the retina. They therefore compensate for and reverse your astigmatism entirely, which leads to the crisp, clear visual acuity you are looking for.

Wearing comfort is always important, and is dependent on how much moisture the lenses attract and retain. Frequency 55 Toric lenses are constructed from methafilcon B, a water-loving polymer that makes each lens have a 55% water content. That creates a high moisture level for your eyes for as long as you are wearing the lenses.

Removing and cleaning the lenses couldn't be easier. They are slightly tinted with a blue handling dye that does not interfere with vision but which conveniently allows you to see and handle the lenses when they are not in your eye.

Your replacement and wearing schedule must ultimately be determined by your vision provider, especially when considering using Frequency 55 Toric lenses for continuous wear. Even if you are already using them for daily wear, you should still speak with your doctor to see if using them for extended wear is fine for you. Not everyone is eligible for extended wear because of different medical needs. Even if you are eligible, you may not be able to wear them for the entire seven days between removals and cleaning. Only your vision provider can tell you for sure.

According to the manufacturer, Frequency 55 Toric lenses have become the fastest-growing segment of monthly replacement soft toric lenses available today. This is no doubt due to a combination of features ranging from total wearing comfort to the low-hassle maintenance schedule. If the convenience and flexibility of daily or extended wear on a monthly replacement schedule appeal to you, consider giving Frequency 55 Toric lenses a try and see for yourself why this brand is becoming a popular choice for astigmatism patients.
