Perfect!
I bought these for my mom who spend the last 5 months of her life confined to a bed and couldn't even sit up to watch TV.  These glasses enabled her to watch TV and movies and, given her situation, they really helped her quality of life.  She would panic if they were ever out of her reach!<br /><br />They are well built and crystal clear.  One of the prisms fell out of her first pair, but that's because she slept on them not because they were cheaply made.  In fact, they are very well made and I would recommend them for anyone, not just those who are confined to bed.<br /><br />Perhaps most importantly, the prisms are mounted "longways" instead of "shortways" (think landscape versus portrait) so that the wearer gets the maximum viewing area.  The prisms are also mounted straight and even.  We tried a different (cheaper) brand where the prisms were mounted "shortways" and were maybe not quite straight, which gave me and my mom a headache within a few minutes.<br /><br />These glasses didn't have any sort of adverse effects such as headaches, eye fatigue, etc.
