Who It's For & Trade-offs
Black shows the strongest contrast on light or hazel eyes and a subtler definition change on already-dark eyes. At 13.0mm, this is one of the more natural-diameter lenses in the range, keeping the size effect subtle. This lens ships one lens per bottle, so two bottles make a full pair. As a 3–6 month lens, it's more cost-effective over time than a daily, but requires nightly cleaning in solution and should be discarded once past its rated lifespan even if still comfortable.

OD = right; OS = left. Enter SPH with its + or − sign. Use 0, PL or plano for zero.

Why can powers differ?
Glasses sit in front of the eye; contact lenses sit on its surface. This distance changes the optical effect, especially at stronger powers. A professional fitting determines your contact lens prescription.
Optical estimate = SPH ÷ (1 − distance × SPH), with distance in metres. This calculation uses sphere only.
