Olens BS 21 Brown Toric is a long-term colored toric contact lens with a 13.5mm graphic diameter and 38% water content, giving eyes a natural brown touch while correcting astigmatism. OLENS lenses are made from HEMA material.
Who It's For & Trade-offs
Toric lenses are built for astigmatism correction, so this suits people who need that specific prescription type rather than a standard spherical lens — fitting can be more sensitive to axis alignment, so proper fitting by an eye care professional matters more than with non-toric lenses. 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.
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 once the lens reaches the end of its 3–6 month rated life, even if it still feels comfortable.
- Toric lenses require a proper axis fitting — consult an optometrist before wearing.

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.
