bifocal中文在Bifocal Glasses - Lenses Great for Reading - EyeBuyDirect的討論與評價
What are bifocal glasses? You can think of bifocal glasses as two pairs of glasses in one: a pair of glasses for everyday wear, and a pair of glasses for reading. That's because bifocal lenses feature two viewing areas divided by a visible line: the larger area is for distance, and the smaller area at the bottom is for reading. Don't look at them as granny glasses or old man spectacles, but rather as the best of both worlds. What Is The Purpose Of Bifocal Glasses? Generally speaking, bifocal glasses serve the purpose of giving you all of the vision correction you need in one pair of glasses. Being able to read and perform close-up tasks without switching to another pair of glasses, or having to carry around a second pair, is a great convenience to many glasses wearers. EyeBuyDirect offers some of the best online bifocal glasses, and they're just a click away.
