Side Effects from Astigmatism
Hits : 1627
No. 1
Even if your prescribed contacts are designed accordingly to your vision, your vision may still be blurry when the axis of contacts is not aligned. When you experience unclear vision wearing these stigmatism contacts, please keep in mind for this cause and examine the contacts and your wearing method. Most cases of blurry vision arise not from wrong prescription but misalignment of axes. 

No. 2
We do not recommend astigmatism contacts for people with dry eyes. Dry eyes cause contacts to firmly stick on the surface of the pupil, and do not rotate: contacts will not change directions freely to enhance vision.
