Works great! But they are on the cheap side.
PROS:<br />- Prisms look and feel of high quality.<br />- Legs are long enough to use them on my prescription glasses. (Laying on the bed)<br />- I really feel relieved from the pain in the neck in just one week of use.<br /><br />CONS:<br />- Plastic frame and legs are cheap and brittle. I'm a guy with a broad face and one leg couldn't withstand the tension and just broke off.<br />- They are, for obvious reasons (Prisms are made of solid glass), slightly heavier than a normal pair of glasses, so...<br />- I can't use them on my prescription glasses while sitting. (I like to play portable video games and read magazines) but they tend to slide out of focus to the tip of my nose. I guess I'll have to play laying down :-P<br /><br />CONCLUSIONS:<br />In general, it's an O.K. product for the price. It works great but with some issues for me.<br />I had some eye fatigue at the beginning, but it went away when you get used to them.<br />Reinforced and adjustable legs and some cushioned nose pads would have been great.
