I heard that Acuvue Advance for Astigmatism contact lenses (Whew!) have a strong tendency to fold up and roll up in your hand when you're trying to put them in. Someone said that it was due to their "non-prism balance design." From what I understand, Toric Contact Lenses for astigmatism have a part of the lens that's a little thicker than the rest of the contact. This acts like a "ballast" and always goes to the lower eyelid and stays stable that way.
How does a contact lens do this without a prism ballast? |
