What are toric contact lenses?

Standard contact lenses are spherical — their power is the same in every meridian. Toric lenses are not: they carry a cylinder correction at a specific axis, and they need to land on the eye in the correct orientation every time you blink.

Stabilisation methods include:

• Prism ballast: a heavier lower portion that uses gravity to orient.
• Peri-ballast: thinned upper and lower edges so the lid pressure orients the lens.
• Dual thin zones: two thin areas at 3 and 9 o'clock for natural settling.

Toric lenses are typically more expensive than spherical ones (15–30% more) and the parameter range (BC + DIA + SPH + CYL + AXIS) makes inventory bigger. Production is also slower since each combination is its own SKU.
