Who It's For & Trade-offs
Gray reads as a cooler, more subdued alternative to brown, showing up most distinctly on dark eyes. At 13.0mm, this is one of the more natural-diameter lenses in the range. As a monthly lens (2 pieces per box), it's more cost-effective per wear than a daily, but requires nightly cleaning in solution and replacement after about a month regardless of comfort.
Safety & Care
- Wash and dry hands thoroughly before handling lenses.
- Store in a clean lens case with fresh solution daily.
- Remove lenses before sleeping, swimming, or showering.
- Replace after one month, even if the lens still feels comfortable.
- Consult an optometrist for proper prescription and fitting.

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.
