Glasses Global Vision Quik Change Kit combined

Glasses are very practical. It's not even 2 in 1, it's 6 in one:
3 options of glasses (transparent, darkened-tinted and contrast-yellow) x 2 options of fastening (shackles and a belt-elastic band).
Some lenses are replaced by others very simply and quickly, like cassettes. The lenses themselves are also excellent, with a scratch-resistant coating.
The only negative-the arms of the glasses are not too comfortable, it would be better with more rounded ends. But if desired, they can be replaced with an elastic band that firmly covers the head from behind. For this replacement, the shackles are unfastened by pressing the button.
A small bonus-there is a case for storage, with a carabiner for which it can be attached to anything. Inside the soft coating, so as not to harm the glasses.
