Understanding Astigmatism
Astigmatism is a common vision condition caused by an irregular shape of the cornea or lens. Instead of focusing light evenly on the retina, the eye creates blurred or distorted vision at different distances.
Common symptoms include:
- Blurry vision
- Eye strain
- Headaches
- Difficulty seeing at night
- Squinting to see clearly
Toric contact lenses are specifically designed to correct astigmatism by incorporating different optical powers and maintaining a stable orientation on the eye.
