Love these glasses! They are an unusual shape so I wasn't sure if they would work for me. I took a chance because Lens Alter offers returns and I am really happy. They are very lightweight, comfortable, and cute. I got blue light blocking/light-adaptive lenses because I have very sensitive eyes when it comes to light and sunlight. Honest review for most cases these are great for the screens we are all constantly staring at and for the sun. The lenses adapt within 10 seconds to lighten or darken and the range of clear-dark is solid. One caveat they do not get dark enough for me for driving, or for prolonged bright, direct, sun exposure say from snow/beach/outside in a bright area. (I use very dark sunglasses for these activities.) If you are very light sensitive these may not work for you as transition lenses for a very bright environment. (I don't know about plain sunglasses from Lens Alter as I've not tried them those may or may not be dark enough.) However on the plus side I finally have really cute sunglasses I can wear in most environments and inside without looking like I'm wearing sunglasses inside. The lenses darken just the perfect amount to shield my eyes without being too dark for lower light settings/daily life inside, or in partial shade. One other thing to note, I got a "normal" size. I have a small head and narrow face and the glasses fit me perfectly. Be sure to measure your face to make sure the glasses will fit you, as I suspect they run small based off how well they fit me. I plan on buying a few different pairs to switch up my style. I would highly recommend glasses from this company based off my experience thus far.
