Special Condition Focus Toric Lenses

The phrasing of CIBA Vision's Night & Day contact lens packaging for North American sales recently changed as the company increased the spherical power range of its Focus Dailies Toric lens, a daily disposable lens for astigmatism. You will be able to purchase toric lenses with range from +4 to -6D in 0.25 to D steps and from -6.5 to -8 in 0.5-D steps, including plano.

Toric lenses help correct astigmatism, a condition caused by an irregularly shaped cornea, which warps the vision. Modern technology has allowed special lenses to be created specifically for the correction of astigmatism, though at one time the condition could only be corrected with eyeglasses. Contacts with dual prescriptions are required for many people with astigmatism, since they can also suffer from near- or farsightedness.

High levels of practitioner skill, large fitting sets and long delivery times were required for soft toric contact lenses for many years, since they were regarded as specialty lenses. Today's stock torics are less costly and simpler to fit, and they also offer superior reproducibility, due to new developments in design and performance, together with advances in manufacturing technology.

CIBA Vision's Focus Dailies Toric contact lenses give astigmatic patients crisp, irritant-free vision because they are replaced with new lenses every day, avoiding any buildup of deposits that can blur your eyesight. The lens material is nelfilcon A polymer.

Focus monthly toric contact lenses are made for patients affected by astigmatism and are designed for use as daily wear lenses for up to a month, after which they should be discarded. These disposable lenses significantly decrease the amount of deposits that can attach themselves to contact lenses and irritate your vision because they are replaced with fresh lenses on a regular basis. The lens material is 55% water and 45% vifilcon A, a hydrophilic co-polymer of 2-hydroxyethyl methacrylate and povidone, USP.
