GlassesUSA is one of the biggest and best eyeglasses online (opens in new tab) retailers in America, with a huge range of eyewear to pick from. If you take advantage of the deal to save you 30% off your entire order (including lenses and frames) for sunglasses and glasses with free Rx lenses, you’ll need to use the discount code USA30. This 30% discount cannot be used on multifocals, progressives, new arrivals, sale items, contacts or premium products. However, you can get 25% off designer frames with the discount code PREMIUM25 (excluding Ray-Ban, Oakley and Costa Del Mar). You’ll also enjoy free shipping on your order, with a clear returns policy in place should you need it. GlassesUSA is also home to the best contact lenses online (opens in new tab), and while you can’t use the 30% off discount on any of those, there is a separate promo code to save you 25%. To use this, plug in CONTACTS25 at checkout.   As for frames, whether you’re shopping for women’s, men’s or kid’s prescription glasses, there are plenty of styles to choose from. From the stylish cat-eye shape to round, rectangular or rimless frames, GlassesUSA stocks a large collection of prescription eyeglasses - and has been doing so since 2003. Once you’ve chosen your frames, you can have them fitted with single vision lenses, multifocal lenses, anti-reflective coats, digital protection or buy sports glasses should you need them. The brand also stocks thousands of big-name brands with the likes of Burberry, Gucci, Versace, Prada and Ray Ban to choose from. GlassesUSA offers a 365-day warranty, so you can rest assured your specs are covered year-round. It also has trained optical experts to offer you customer support 24/7, should you need any help.  Anyone who wears glasses will know how hard it can be to find frames that suit you, let alone when buying online, which is why we like the virtual try-on service. This enables you to see how different frame shapes and colors look on your face. If for some reason you aren’t happy with your glasses, as long as you return them within 14 days of receiving you’ll get a refund.
