Selling blue lens is one of the common upscale tactics to earn more profit.

Despite many push from the indsutry for researcher to produce a benefit report of blue lens. So far still no onclusive study thqt said blue lens help. So u can imagine how useless this upgrade other than give u blue tinted glasses.

As for lens that can relax. This is new to me. New scam? The wallet definitely not relax after hearing the price.
