Astigmatism contact lenses are vision correction tools designed specifically for correcting astigmatism. When corneal astigmatism is greater than or equal to 0.75D, ordinary spherical contact lenses cannot fully correct it. At this time, customized astigmatism contact lenses are needed to correct astigmatism. At the same time, non-corneal astigmatism (mainly caused by lens astigmatism) can also be corrected by customized astigmatism contact lenses.
Product Features
Customized design: Astigmatism contact lenses adopt a hyperbolic design, and the curvature radius of two mutually perpendicular meridian positions is different to correct astigmatism.
Stability: The most important design of customized astigmatism contact lenses is the stability of the lens, keeping the astigmatism axis stable to correct astigmatism.
Multiple stabilization principles: including prism vertical weight method, bilateral thinning method and edge cutting method, etc., to ensure that the lens is correctly positioned in the eye.
High oxygen permeability: Use highly oxygen permeable materials, such as silicone hydrogel, to improve eye health and comfort.
Anti-ultraviolet function: Some products have anti-ultraviolet function to protect the eyes from ultraviolet damage.
Applicable people
People with astigmatism above 0.75D.
Astigmatism patients who need to wear contact lenses for a long time.
Astigmatism patients who have high requirements for the oxygen permeability of lenses.
People who fail to wear due to poor visual stability
.
Selection suggestions
For astigmatism of about 100 degrees or more, it is recommended to wear astigmatism contact lenses to avoid double vision and eye fatigue
.
The positioning methods of astigmatism contact lenses mainly include gravity positioning and blinking positioning, and different designs meet the needs of different users
.
Precautions
Astigmatism contact lenses are customized products, and the astigmatism degree and axis position need to be accurately measured.
The correction effect of astigmatism contact lenses is closely related to the stability of the lenses, and it is necessary to ensure that the axis position of the lens is consistent with the axis position of the astigmatism
.
The oxygen permeability and comfort of astigmatism contact lenses are important considerations when choosing
