For people with prescription glasses, going to a 3D movie isn't exactly great since they'd have to fit another pair of glasses over the existing ones; however, the LG AG-F220 aims to solve that problem.
The LG AG-F220 are actually clip-ons that go directly onto prescription glasses so it's basically like clip-on shades, but for the movie. This means individuals will no longer have that extra bulk that never fit well anyway. These will provide the same eye-popping effects that regular 3D shades do so that everyone gets the same enhanced movie experience.
Considering how every movie these days seem to have 3D technology integrated in them, the LG AG-F220 may be worth an investment for those with prescription glasses. It's fitted and more comfortable than the alternative.
