PRATS LENSES FOR ASTIGMATISM
Astigmatism is a visual condition you can correct with PRATS lenses. Our lenses for astigmatism can be positive (converging) and negative (diverging), or even mixed, but before we explain which ones you need, let’s start with the basics.
What is astigmatism
Astigmatism is characterized by distorted or blurry vision at any distance.
It occurs when the cornea or the crystalline lens has an irregular curvature, so light does not focus on a single point on the retina. As a result, a person with astigmatism receives a blurred image, which often leads to greater eye strain, the need to squint, and headaches.

Whatastigmatism lenses should have
Astigmatism is a refractive error that is compensated with toric lenses. These lenses incorporate exact powers on the appropriate axes, maintaining optical stability and precision under all wearing conditions.
Not all astigmatism lenses are the same. There are more basic solutions with standardized designs, and more customized lenses in which we optimize the surface calculation for greater visual quality and comfort.
Astigmatismwith myopia
How does it happen? The light entering the eye is projected in front of the retina in two different focal points.
Consequences and solution:
It causes distance blur that requires correction with negative toric lenses.
Astigmatismwith hyperopia
How does it happen? The light entering the eye is projected behind the retina in two different focal points.
Consequences and solution: It causes difficulty seeing up close and requires correction with positive toric lenses.
Astigmatismmixed
How does it happen? One focal line is projected before reaching the retina, while the other is located behind it.
Consequences and solution: It causes difficulty and discomfort seeing at all distances. It is corrected with mixed toric lenses.

Complete your lensfor astigmatism
All PRATS lenses include treatments and solutions that provide additional properties and improve visual quality. Here are the recommended ones for lenses related to astigmatism.
TRANSPARENCYAND AESTHETICS
The QUARZ AironUV+ anti-reflective treatment provides total lens transparency. You see and are seen with complete clarity.
BLUE LIGHTPROTECTION
There are treatments that block harmful blue-light radiation. QUARZ BlueUV and CSR are PRATS solutions. We also offer the Blue Safe System material for the same purpose.
PHOTOCHROMATIC
PhotoChrom lenses automatically adapt to the intensity of sunlight, darkening or lightening depending on the environment. This way you won’t have to switch between regular and sunglasses, and your eyes will always be protected against UVA and UVB rays.
