Frequency 55 Toric contact lenses for astigmatism from Coopervision are an increasingly popular brand of toric lenses. They feature superior comfort and visual acuity on a flexible monthly replacement schedule. You can wear and remove them every day, or optionally use them for up to 7 days of extended wear.
Frequency 55 Toric lenses fix the odd shape of the cornea, the unique problem experienced by astigmatism sufferers. The normal cornea is shaped like a sphere, but the astigmatic one is shaped more like a football. This odd shape causes rays of light to scatter rather than focus directly on the retina, which ends up causing the blurry vision you’re used to without correction.
Frequency 55 Toric lenses correct your astigmatism, once they are securely in place, by acting as a refracting medium that re-focuses rays of light properly on the retina. They therefore compensate for and reverse your astigmatism entirely, which leads to the crisp, clear vision you are seeking.
Wearing comfort is essential, and primarily depends on the amount of moisture the lenses attract and retain. Frequency 55 Toric lenses are constructed from a water-absorbing polymer called methafilcon B. Each lens has a 55% water content, which creates a high level of moisture for your eyes for as long as you are wearing your lenses.
Removal and cleaning of the lenses are easy. Each lens is slightly tinted with Reactive Blue No. 4, a handling tint that does not at all interfere with eyesight but which conveniently allows you to see and handle them when they are not in the eye.
Your wearing and replacement schedule must ultimately be decided by your eye doctor, especially when considering using Frequency 55 Toric lenses for continuous wear. Even if you are already using them for daily wear, you should still consult with your doctor to see if using them for extended wear is fine for you. Not everyone is eligible for continuous 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 eye doctor can tell you for sure.
Frequency 55 Toric lenses have become, according to the manufacturer, the fastest-growing segment of monthly replacement soft toric lenses available on the market today. This may well be due to the combination of total wearing comfort, flexible wearing schedule, and low-hassle monthly replacement. If these features appeal to you, consider giving Frequency 55 Toric lenses a try and see for yourself why this brand is becoming such a popular choice for astigmatism patients.
