Photochromic, Polarized or Just Tinted Sunglasses?
There are quite a few choices when it comes to selecting sunglasses but which is best for you when you are selecting your prescription sunglasses?
Let’s Look at Photochromic Lenses
You may know these as light reacting or reactolite or photosensitive – they are all essentially photochromic lenses which react to UV light and darken according to the levels of light.
There are many makes available and “Transitions” is maybe the best-known brand. These are great if you only want one pair of glasses and if they clear when indoors then all is good?
Well, there is one downside – your car windshield will also block most of the UV, so leaving the photochromic lenses with no UV to react to and staying clear! If you have any source of UV whilst indoors such as UV lighting then they may also keep some light tinting on the lenses which you may not want.
The only downside is that they will also block the LCD displays on your car dashboard so might not be ideal for driving.
Maybe the best all-around option for driving in the sunshine as they do not have any downsides and you can select different levels of tint. They will block 100% all UV light also.
