Toric contact lenses are designed to correct astigmatism and need to remain positioned correctly on the eye to provide stable vision.
What Is Astigmatism?
Astigmatism is a common refractive error that can cause blurred or distorted vision and may require cylindrical correction.
How Toric Lenses Differ
Toric lenses have different powers in different meridians and include design features that help orient the lens correctly.
Why Fitting Is Important
Lens rotation, movement and comfort can affect vision, so trial fitting and follow-up may be needed.
Can Everyone With Astigmatism Wear Contacts?
Many people can, but suitability depends on prescription, eye health, available parameters and fitting.
Frequently Asked Questions
Why do toric lenses sometimes blur when I blink?
Lens rotation or movement can temporarily change the effective correction. Persistent instability should be reviewed.
Are toric lenses more expensive?
They can cost more than simple spherical lenses because the design and parameter range are more complex.
