Toric Contact Lenses For Minus And Cylindrical Eyes?
Good morning, thanks for the question
Astigmatism or astigmatism is a condition where light is not transmitted at the same focal point on all meridians due to abnormalities in the cornea or lens.
This condition can be corrected with glasses or contact lenses. Both have advantages and disadvantages of each. For comfort it is better with contact lenses because it attaches directly to the eye so that no field of vision is blocked, whereas if you use cylindrical glasses peripheral vision will look blurred.
The type of contact lens for cylindrical eyes is also adjusted to the degree of severity due to several types of contact. There are toric, rigid, or hybrid types. Toric contact lenses are contact lenses that are specifically designed to correct astigmatism. Toric contact lenses can also be designed to have 2 strengths, namely to correct astigmatism, and myopia or hypermetropia is called toric bifocal contact lenses. Most toric contact lenses are soft contact lenses made from silicone hydrogels or hydrogels.
Because each astigmatism condition is unique and different, more than one pair of torque contacts can be needed to get the most suitable and comfortable size. In addition, the measurement of toric contact lenses is not easy so it requires more expensive costs than ordinary contact lenses. Also because the design is more complex then the cost for the replacement will be more expensive. It is recommended that you consult with an eye doctor to adjust the type and size of contact lenses that are suitable for your needs.
That's all, hope you can help
