Exploring the types of lenses for astigmatism

Astigmatism is linked to distorted and hazy eyesight. It generally occurs due to an imperfection in the eye’s curvature. Corrective contact lenses are a viable option to improve the vision in such cases. People can consider several types to determine which will provide the greatest vision correction. Toric, gas permeable, and hybrid lenses are the three well-known kinds of contact lenses for astigmatism. Read on to know what these lenses do and how different they are from each other.

Toric contacts
Soft toric lenses correct the imperfection in the eye with meridians of different powers. Their three-dimensional CD-like design lets the lens rotate and adjust the correction. When aligned with the right power, the vision is clear. Different kinds of design features are available. Some have thick and thin zones, some are slightly sliced up at the bottom, while others are heavier than the standard ones. People will have to try different toric lenses to find the one that fits the eyes perfectly.

Gas permeable (GP) contacts
Gas contacts act as a substitute for the malformed cornea. With this type of lens, the light is able to reach the retina in such a way that it lends sharp clarity to the eyes. Although GP lenses are generally more firm than toric ones, they have breathability that allows the eyes to feel comfortable. This also ensures that the surface of your eyes is protected and enough oxygen reaches it. There are some GP contacts that come with a torrid design, but these contact lenses are for astigmatism of a high level.

Hybrid contacts
A hybrid lens is like the all-rounder of lenses. It combines the advantages of both gas permeable and toric lenses. A hydrogel fitting zone surrounds a rigid gas permeable lens. It lends a soft and relaxing effect similar to toric lenses and renders a clear vision, much like a GP lens. Hybrid lenses are about the same size as toric lenses, but the corners are thinner than GP lenses. When someone is practicing a high-intensity activity, hybrid contacts decrease the chance of lens dislodgement.

When buying contact lenses for astigmatism, ensure that you have a prescription from an eye doctor and an appointment to fit the lenses. Fitting is crucial. When done right, your vision will get better, and your eyes will stay safe under the lens.
