Frequency 55 Aspheric

Frequency 55 Aspheric contact lenses are soft disposable lenses that feature a sharper focus and superior comfort that out performs most regular spherical lenses.  Aspheric design, which means the lens has two or more curves, allows light to become more tightly focused on the back of the eye, or retina, where vision takes place.  The result is a flatter lens, with crisper, sharper images and better visual acuities.

Frequency 55 Aspheric lenses are monthly replacement lenses, meaning that one pair can be worn for a month at a time with proper storage and disinfection.  The lens is comprised of methafilcon A, is a breathable silicone hydrogel with a 55% water content, which provides for more comfortable wear. Frequency 55 Aspherics are manufactured with Coopervision’s patented  Ultrasync process, which results in a thinner edge providing maximum comfort with every blink. Aspheric designs have been used for decades on spectacle lenses to provide superior vision by reducing abberation and lens edge thickness.  Abberation is unwanted reflections of light that can be caused by a sharp front curve resulting in blurriness and color distortions.  The two or more curves on the front surface of an aspheric lens reduce this effect by creating a smaller flatter front curve with less surface reflections and better performance.  Aspheric lens design is invaluable to those with strong prescriptions (+/- 4 and above).

Most visual problems of the eye usually have to do with the shape of the eyeball and cornea. The cornea is the clear part of the eyeball directly over the pupil.  A normal eyeball is round and without refractive error.  This means light passes directly through the cornea and is focused directly on the retina resulting in 20/20 vision.  When the cornea is oblong, or football shaped, the result is light is separated into two focus points, the result of which is called an astigmatism.  If the eyeball is longer, or egg shaped,  the resulting light will focus in front of the retina causing myopia, or nearsightedness.

If the eyeball is shorter, or oblong shaped, the light will focus behind the retina causing hyperopia, or farsightedness.  An astigmatism is where light comes into focus in two points.  An astigmatism will require two different curves in specific meridians of the lens to bring light into one focal point directly on the retina.

The Frequency 55 Aspherc lens has high (55%) water content providing for comfortable wear. Soft contact lenses have a tendency to take moisture off of the eye, which make eyes feel dry and itchy. A higher water content in the lens itself is very beneficial, for it keeps moisture on the eye, which reduces irritation and promotes good corneal health.  As soft contacts age they tend to loose moisture and dry out.  The more water a lens has in it the longer the lens will feel comfortable in the eye.

Another key feature of the Frequency 55 Apheric lens is its ability to block damaging UV rays. Frequency 55 Aspherics provide crisp vision along with comfort making them ideal for those looking for a quality monthly disposable lens.
