Do Polarized Sunglasses Need Anti Reflective Coating?
People who spend a significant amount of time outside can benefit from protecting their eyes with the use of sunglasses. Both polarized and anti reflective sunglasses are beneficial in reducing the amount of glare as well as the harmful rays of the sun from reaching the eyes though
Polarized sunglasses are already effective in preventing the surface glare that bounces into your eyes on the front of the lenses from your environment such as the sea, snow, or the road.
On the other hand, anti reflective coating especially on the backside of the lens improves vision and clarity because it blocks light from bouncing off the back of the lens. Anti reflective coating is not necessary for polarized sunglasses but they can be beneficial for those who still experience glare, reflections, and sunlight from odd angles.
This can occur especially if your sunglasses let light leak through the top and sides of the frame, causing an annoying glare that can make vision difficult. In this case, the use of additional anti reflective coating on the rear surface of the lens prevents any light leaks from reaching your eyes. Thus, it can help improve overall vision when added to polarized sunglasses.
Conclusion
Polarized sunglasses don’t need anti reflective coatings because they already efficiently block glare. In some cases, people can find it useful to add anti reflective coating behind the lens’ rear surface to prevent excess light from the sides and top of the frame.
