Polarised lenses are a sunglasses-specific lens designed to reduce glare and improve visual clarity. They use a chemical filter within or upon the lens which diminishes reflected glare from flat shiny surfaces such as water, snow or ice. They're especially popular for water-sports or driving to reduce visual fatigue over long periods of exposure. They can be CR39, polycarbonate or glass. The first plastic eyeglass lenses were introduced by Armorlite Lens Company in California in 1947. While there have been numerous advances in eyeglasses since then, CR-39 plastic is still known for its excellent optical quality, durability and low cost. But the rumours are true. They can be incredibly heavy, bulky and yes, they can shatter like in the old movies. We also appreciated their weight, which reinforces the impression of superior craftsmanship and suggests they should last a long time if cared for properly. The sunglasses offer a snug, comfortable fit ideal for leisure pursuits (although one of our testers did find that there was some light leakage around the edge of the frame on particularly bright days). The lenses are made of mineral glass for the best quality optics, definition, and contrast, with an anti-reflective coating and 100-percent UV protection. Choose from five gorgeous colors, including Blush and Tortoise.Polycarbonate is much lighter and thinner than other lens materials but can be very expensive depending on your prescription.

Partially, your smartphone will also have a bit of a bluish tint towards purple depending on what angle you hold it at.
