There are beaucoup benefits to buying glasses online. But picking the right retailer can be tough AF. Finding a brand that offers dope deals and stylish selections is tricky. Enter: DIFF Eyewear. This charity-focused brand has been selling spectacles since 2014.

DIFF Eyewear is partnered with Sightsavers, an international charity that provides funding to help folks get vital eye exams, surgeries, and medicine. According to DIFF Eyewear’s website, it has provided over 1.6 million peeps with reading glasses. We love to see it 👀.

While we’re all about giving back, there’s more to consider when buying glasses (cuz hey, you need to be able see, right?). Keep reading for our deep-dive into all the deets on DIFF eyewear.

The company offers hundreds of DIFF-erent frames (see what we did there?). You can sort through the selection with these filters:

  • color
  • square
  • rounds
  • cat eye
  • aviators
  • polarized
  • collection
  • oversized

Alas, there’s no way to try on the glasses before buying — virtually or at home — which is a big bummer. But you can take a quiz to see which frames are best for your face shape and overall style.

Here’s a rundown of DIFF’s different products:

Prescription eyewear

While the company has a wide selection of frames to choose from, DIFF can only fill some prescriptions. If you wear progressive, multifocal, or bifocal lenses, you’ll have to keep shopping. If you’re a single vision wearer, the lenses are made from a premium scratch resistant polymer, so they should last a long time. You can also add on blue-light-blocking to your prescription glasses and upgrade to thinner lenses for $35 a piece.

If you end up falling in love with a pair of DIFF frames, you can always buy them without a prescription and take them to a local optician to get them fitted with your Rx.

Sunglasses

DIFF has a super selection of snazzy sunglasses for all styles and face shapes. You’ll look fly and protect your eyes from the sun. You can opt for traditional polarized or nonpolarized lenses. You can also go for the photochromic lenses (these bad boys get darker in light).

Blue Light Glasses

Some studies suggest blue light glasses can help combat digital eye strain. While we need more research to show this is 10/10, lots of peeps say these lenses are legit. If you want to test them out yourself, DIFF offers over 300 blue light glasses. Some of them can be fitted with Rx lenses, too.

Most frames are in the $80 to $109 range. But the price really depends on what upgrades you go for. Blue-light-blocking lenses will bump you up $35. Thinner lenses are also an extra $35. Polarized sunglasses are an additional $50 while photochromic lenses are $100.

This price range is pretty on par with other online glasses retailers — though a set of specs from DIFF might end up costing you a little less because there are fewer upgrades to choose from.

DIFF Eyewear offers a 14-day exchange policy if your prescription specs don’t pass the vibe check. You also get a 30-day return on nonprescription glasses.

Glasses will come with a 1-year warranty that starts on the date of purchase. Just keep in mind that it only covers manufacturing defects. But remember you can always purchase that 2-year protection plan for an extra $15.

PSA: If you do need to return your Rx glasses, you won’t get your money back. DIFF only offers store credit for returns.

You can order DIFF Eyewear glasses directly from its website. Reminder: There isn’t any kind of try-on feature. If you want to give your glasses a whirl before purchasing, you might get lucky and find some products in select stores across the U.S., like Nordstrom and Revolve.

When you’re ordering, be prepared to choose your upgrades (like blue-light-blocking and/or thinner lenses) and whether you want to add a 2-year protection plan (ideal for our clumsy baddies prone to accidental damage).

You’ll also need to either upload your latest eye prescription (make sure it’s not expired!) or email it later. It should include your PD measurement and lens strength. An in-house optician will look over your Rx to make sure you get the correct lenses.

Insurance

Diff does NOT accept health insurance. You also can’t use your flexible spending accounts (FSA) or health savings account (HSA) cards. But you can ask for a receipt to submit to your insurance provider for possible (usually partial) reimbursement.

What about shipping?

According to its website, most prescriptions are processed within 14 business days. Non-Rx orders only take 1 to 2 days. All orders are shipped from Los Angeles.

Orders $115+ come with free shipping in the U.S. and you can also have your glasses shipped internationally but you might need to shell out some extra clams for tax or import fees.

DIFF isn’t the only eyewear game in town. Here are some other top-notch online glasses stores.

Best overall: Warby Parker

Warby Parker has a hella impressive selection of prescription glasses, blue-light-blocking glasses, and sunglasses. The company is also known for its quick and easy contact lens options. WP has at-home try-on, virtual try-on, and you can also visit one of its brick-and-mortar locations.

Best budget: EyeBuyDirect

EyeBuyDirect has fab frames that are great for your peepers and your budget. You can find the perfect pair for under $40. Folks also dig its 14-day return policy. Bonus: The company accepts HSA and FSA debit cards. Score!

Best variety: GlassesUSA

GlassesUSA has something for everyone. Really, tho. There are over 7,000 frames plus lots of customizable features to choose from. The company also has a super solid customer service track record and a reasonable return policy.

Best virtual try-on feature: Eyeconic

Eyeconic has a top-notch virtual try-on feature. You can treat yo’ self to designer brands like Gucci, Ray-Ban, Saint Laurent, and Chloe. But don’t worry, the brand sells lots of fab budget-friendly frames too.

While DIFF Eyewear def has some perks, the customer reviews are a bit underwhelming. You might be better off using another service if you have Rx lenses. But if you’re more interested in stylish, fairly priced frames, DIFF is where it’s at.
