Sadly If you're bursting in and out of shadowy forests or zipping through dark tunnels, the slow reaction time of such Photochromic [PC] glasses just can't keep up, but Photochromic glasses are great for things like heading out on evening bike rides, as their tint gradually lightens while the sun goes down.
Photochromic sunglasses automatically change color based on light conditions, letting more light in during dark, low-light conditions and blocking more light when it's bright and sunny.
That's where these PC glasses come in, which use electrochromic technology to change tint in almost a tenth of a second. Photochromic glasses have the ability to darken in sunny conditions and revert to a lighter shade when the wearer moves indoors.
Photochromic glasses are useful for sports where light conditions can change quickly. Photochromic lenses are a feature that typically are not found on low-end sunglasses. Sport sunglasses with photochromic lenses are likely to run between $100 and $350.
Drops Of Jupiter sells solid sports sunglasses for a lower price, offering a number of photochromic glasses for $39 to $97.

SIZE GUIDENOTICE: Be very careful with sizing, when an item refers to sizing make sure it is the correct size. Clothing fitting sizes vary all over the world. For example Asian sizes are TWO (2) sizes smaller than USA sizes, mainly coz American men have bigger "flahulachs"… Got ya there! So get your mind out of the gutter! LOL !
For the truly paranoid, if in doubt, order one, wait until it is delivered and try it on…?
WRONG size? Oh Well that's now a cheap Christmas Present isn't it.
Order up two sizes next time, so you know then.
