When facing extremely bright light outdoors while driving or out on the sea or even while playing some sport, a good set of sunglasses is essential. There are many good sunglasses in the market and picking up the right one can be difficult. Let us consider the Oakley Polarized Black Iridium vs. Vr28 Polarized Black Iridium. Which of these two sunglasses suit your purpose?

Polarization is the process of sandwiching a thin layer of iodine crystals into the middle of a lens. This process cuts the glare even while it allows light to pass through the lens. Polarized lens are extremely good in brilliantly bright light conditions like out at sea or on snow-capped peaks while skiing. They are also good for photo-sensitive patients who have undergone eye-surgery. Iridium, on the other hand, consists of a special metal oxide coating on the lens. This controls the amount of light that is let through the lens. So essentially these are two different processes but are often used together to produce the best possible sunglasses as with the two in question. Both are polarized and iridium coated, both can be used in extremely bright sunlight conditions, and both have a good protection index of 3.
The Oakley Black Iridium Polarized allows light transmission up to 9% while the Vr28 Black Iridium Polarized allows light transmission up to 10%. The primary difference between the two is that the Vr28 offers a contrast lens while the Oakley offers a neutral lens. The contrast helps in better depth perception while the neutral helps provide truer color perception. So it essentially boils down to what activity you are planning to do while wearing your sunglasses?

If you are likely to encounter more shadows as against an open terrain with no shadows, then you would need to go for the contrast lens. While in totally open terrain, the neutral glasses would be preferable. So if you are looking for sunglasses for driving or biking where the texture of the road and shadows from trees has a role to play in your vision, it would be a good idea to choose the Vr28. This is also good for spotting a small white golf ball against a blue sky even at some distance. However if you plan to be out on a snowy white mountain or on the open seas, then the more neutral Oakley Black Iridium Polarized might just work better for you. Either ways, both are a great pair to own.
