We all know that we need to protect our skin in sunlight. The eyes are no different. UV400 blocking eyewear is essential for all.
Available as photochromic (a tint that adapts to the conditions; some versions change quicker and go darker than others) or sunspecs (with or without prescription, polarised or non-polarised).
High quality tints will improve visual comfort, reducing glare and improving vision as well as reducing tension around the eyes and forehead.
