Toric contact lenses are a type of contact lens designed to correct astigmatism, a common condition where the cornea or lens of the eye is irregularly shaped, causing blurred or distorted vision. Unlike regular contact lenses, toric lenses have different powers in different meridians of the lens to compensate for the irregular shape of the eye. This allows the lens to align properly with the cornea and provide clear vision for individuals with astigmatism. Toric contact lenses are available in both soft and rigid gas permeable materials. **

It is important to consult with an eye care professional to determine the best option for correcting astigmatism based on the individual's prescription and visual needs. **
