WHEN ARE TORIC CONTACT LENSES
spherical lenses for sufferer of astigmatism. The lens shape contains a gradually varying degree of strengths, accommodating for the different amounts of vision in each part of your eye, and sits comfortably over its elongated shape. Many toric lenses are designed to be thicker at the bottom, using a technique called prism ballasting.

This means that the bottom of the lens weighs more, so that gravity, as well as pressure from the upper eyelid, squeezes the thicker part of the lens out from under the upper lid. The lid pressure from blinking then keeps this in place.
