It took way too long for this to happen, but high quality clip-ons are finally available.
Every 3D film that comes to theaters means that prescription lens wearers have to make the decision between watching the 2D version or suffering through an uncomfortable viewing experience. Thankfully, clip-on attachments are finally becoming available.
You can find cheap clip-ons sold on Amazon for around $10, but reviews are mixed - some saying that the attachments don't work at all. It's a possible solution, but not an elegant one. The elegant one comes this spring when Marchon releases its 3D Ultraclips.
Instead of literally clipping to your frames, 3D Ultraclips utilize micro-magnets to hold snug to your glasses. It makes for much lighter and more comfortable frames.
3D Ultraclips are also photochromic, and darken into sunglasses when taken outside. This ensures that you can get the eye protection you need outside and the maximum amount of light penetration when you're watching a movie indoors.
Sadly Marchon hasn't made images of their clips available yet.
