I really like these glasses and they are much cheaper than the ones I've been looking for in big stores which are $45. I have a very low magnification (1.25) so the transition at the lens may not be as clear as at higher magnification. I don't think they are intended for looking across space unless you need distance vision correction as there is slight magnification at the top of the goggles. My friend needs a much higher magnification than me (2.5) and is having trouble getting the magnification on top of this lens. That's why he uses the FG brand, but has to pay a lot more for a pair, and generally they aren't the best quality. As for the blue light blocking ability, I tested these with a kit I got from other blue light blocking glasses and they block all blue light.
