[Philip Lelyveld comment: they appear to have a very dark tint!]
Viewing 3D cinema is a truly gripping experience but for the 3D glasses! Besides being heavy and awkward for those already wearing numbered glasses, they are a material waste and pose a health hazard. Stix offers an easy solution by being a pair of self-adhesive sticker 3D viewing films. Simply slap them onto your current numbered glasses and enjoy your 3D movie.
The stickers are cut out a shape bigger than average glasses to ensure they cover till the rim. The concept’s approach resonates with me, since I wear glasses too and find wearing additional glasses a hassle. Hopefully the sticker in Stix will be easy to peel off and then we are assured of a winner here!
