What kind of eyeglasses is best for my aunt?

[discount classes]

I just want to buy a pair of computer eyeglasses for my aunt, she is not near-sighted, and her eyes always get strain and fatigue after long time working on computer, she needs eyeglasses with special lens coatings which may provide me radiation protection, 1.49 lenses are enough, anyone can give a piece of advice on buying this kind of glasses? And she is 47 years lady and not interested in designer, fashion etc, which frame will do the job?
