The Extreme H2O Toric MC (Moisture Core) contact lenses are designed to correct astigmatism while providing excellent comfort and hydration for the wearer. Here is some general information about the Extreme H2O Toric MC lenses: 1. Astigmatism Correction: These lenses are specifically designed to correct astigmatism, which is a refractive error caused by an irregularly shaped cornea or lens. The toric design of the lenses ensures that the varying powers in different meridians of the lens align properly with the irregular shape of the eye, allowing for clear and accurate vision. 2. Moisture Core Technology: The "MC" in the name refers to the Moisture Core technology used in these lenses. This technology involves incorporating a high water content material in the central area of the lens, which helps to maintain optimal moisture and hydration on the surface of the lens throughout the day. This feature can be beneficial for individuals who experience dryness or discomfort while wearing contact lenses. 3. Comfort and Hydration: The Extreme H2O Toric MC lenses aim to provide exceptional comfort for extended wear. The moisture-rich material and design help reduce friction between the lens and the eye, minimizing irritation and dryness. The lenses are intended to maintain a comfortable and moist environment for the eyes, even in challenging environments. 4. Customized Fit: Like other toric lenses, the Extreme H2O Toric MC lenses require a proper fitting process to ensure optimal vision correction. It is important to consult with an eye care professional or optometrist who can evaluate your specific prescription and eye characteristics to determine the correct lens parameters, such as base curve, diameter, and cylinder axis, for an accurate fit. Remember, its always recommended to consult with an eye care professional or optometrist for a thorough examination and fitting to determine the most suitable contact lenses for your individual needs. They will provide personalized advice and guidance based on your specific prescription and eye health.
