bifocal lens 在 Bifocal Glasses - Lenses Great for Reading - EyeBuyDirect 的相關結果
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. ... <看更多>

How do bifocal glasses work? Bifocal glasses feature two types of prescription lenses connected together in one lens. The top half is designed to see objects from far away (distant) when walking or driving. The bottom half is used to see objects nearby (near) when reading or working on the computer. Wearers can easily shift between the two prescriptions for optimal comfort and better vision. MarvelOptics.com has high-quality bifocals online at unbeatable prices. What are bifocal glasses used for? Bifocals are needed as old age tends to weaken both near and distance vision power. These glasses offer vision correction for folks dealing with myopia, hyperopia, presbyopia, and astigmatism. Bifocal reading glasses reduce eyestrain and headaches while allowing wearers to read or work on their computers comfortably. These spectacles feature a distinct line which allows you to adjust vision for both nearsightedness and farsightedness. Marvel Optics even has no line bifocals with anti-scratch, anti-glare, and other essential features. ... <看更多>
