Sunglasses do two jobs at once. They cut brightness so you can see, and they stop ultraviolet light so your eyes are not quietly taking damage all summer. Only one of those jobs is visible, which is why knowing where to buy sunglasses matters as much as knowing which brand you want. A dark tint with no ultraviolet filter is worse than wearing nothing.

Sunglasses Explained: What They Are and Who They Help
Sunglasses are tinted eyewear designed to reduce visible brightness and stop ultraviolet radiation before it reaches the human eye. The second job is the medical one. The American Academy of Ophthalmology, the largest association of eye physicians in the United States, recommends lenses that block 99 to 100 percent of both UVA and UVB rays, a claim usually printed on the tag as UV400 or “100% UV protection.” Read the Academy’s eye health guidance for the clinical version.
The FDA, the federal agency that regulates medical devices, classifies sunglasses as Class I devices. That sets a baseline for labeling. It does not certify any individual pair’s optical quality, and compliance with the ANSI Z80.3 standard is voluntary rather than federally mandated.
Who needs a good pair? Drivers, boaters, cyclists, skiers, people recovering from LASIK, and anyone on photosensitizing medication. Children need eye protection most of all, since young eyes pass more ultraviolet light to the retina.
How to Choose Sunglasses: Features That Matter
Check the ultraviolet rating first, the lens material second, and the fit third. Everything after that is preference.
Ultraviolet rating. Look for UV400 or “100% UVA/UVB” on the tag or etched into the corner of the lens. Tint darkness is not a proxy for sun protection. A very dark pair with no ultraviolet filter opens the pupil wider and admits more damaging light.
Lens material. Polycarbonate and Trivex are shatter-resistant and the default for sport and for kids. Glass gives the sharpest optics and resists scratching best, but it weighs more and can break on impact. CR-39 plastic sits between the two.
Glare control (polarization). Polarized lenses cancel horizontal reflected light off water, snow, and wet asphalt. Anglers and highway drivers notice within seconds. Pilots and downhill skiers often skip the treatment, because the same effect hides icy patches and washes out an LCD panel.
Lens color. Gray keeps colors neutral and is the safe default for driving. Brown and amber lift contrast on grey days. The G-15 green-gray tint Bausch & Lomb developed for the original pilot frame still anchors the classic metal frame catalogue. Gradient lenses run dark at the top and clear at the bottom, so you can read a dashboard.
Fit and shape. A frame should sit level, clear your lashes by about a fingertip, and never squeeze at the temple. Wraparounds and oversized shapes shield side light better than small rectangular ones. Face shape is a style question, not a safety one.
Rx options. Every vision chain and most premium labels will cut a prescription into a sun frame, progressives included. Budget 80 to 250 dollars over the sticker price, and expect a longer wait than stock sunglasses.
Sunglasses Buying Mistakes to Skip
No ultraviolet label anywhere. If the tag, the sticker, and the product page all stay quiet about a rating, assume there is none. Gas station spinner racks are the usual offenders.
Counterfeit designer sunglasses. Fakes of Oakley, Persol, Prada, and Gucci circulate through third-party marketplace listings. The tells: a crooked logo, a wobbling hinge, missing screws, rough edge polish, and a price far below any authorized dealer. Counterfeits rarely carry a real ultraviolet coating, which turns a wallet problem into a health one.
Shopping by tint darkness. Darker is not safer. The darkest unlabeled pair on the rack is the worst thing you can put on your face.
Skipping the try-on. Anything that creeps down the nose or pinches behind the ears ends up in a drawer within a month.
Novelty kids pairs. Children’s eyewear should be impact-rated polycarbonate with a stated rating. ASTM F803, a sports eye protector standard, is worth looking for if the child plays racquet sports.
Cleaning with a shirt tail. Dry cotton drags grit across the coating and causes most scratching. Rinse with lukewarm water, then dry with a microfiber cloth.
Which Stores Carry Sunglasses
Four chains cover most of the in-person market: Sunglass Hut for designer labels, LensCrafters and Costco for prescription work, and Walmart or Target for anything under 30 dollars.
Sunglass Hut
The largest specialty chain in North America keeps Oakley, Prada, Persol, Versace, Costa Del Mar, and Maui Jim on one display wall, which makes it the fastest place to try five labels back to back. Stock skews to current-season hero styles rather than depth. Use the store locator first.
LensCrafters
The right call when you need Rx work turned around quickly. Many locations run an on-site lab and share space with an independent optometrist for walk-in exams, and the wall carries Oakley and Coach.
Walmart and Target
Budget frames from Foster Grant, Panama Jack, and store labels run 10 to 25 dollars, and both chains sell licensed designer pairs through their vision centers. Target Optical carries the Quay Australia collection.
Costco Optical
Warehouse departments stock Oakley and Costa Del Mar at member pricing and cut Rx work in house. Membership is required to buy, though not to sit an eye exam.
Run a 30-second fit check before you pay:
- Face the mirror straight on. The pair should sit level with your brows, not tilted.
- Nod once, hard. If it slides down your nose, the bridge is too wide.
- Turn your head side to side. The arms should hold without gripping.
Timing matters too. Displays refresh from April through August, and last season’s stock gets discounted from roughly October through January.
Best Places to Order Sunglasses Online
Selection and counterfeit risk both peak online, so who you buy from matters more than which site you open.
Amazon
The deepest range anywhere, from 15 dollar throwaways to 400 dollar glass lens builds, with next-day delivery on most Prime items. Buy from listings marked “Ships from and sold by Amazon.com” or from an official brand storefront, since third-party sellers are the entry point for gray market stock. Browse the glare-cutting selection.
Warby Parker
Direct-to-consumer acetate styling starts around 95 dollars with sun lenses included. The home try-on program ships five pairs free for five days, which solves the fit problem the internet usually creates.
Manufacturer Sites
Ordering from Ray-Ban’s own storefront, Oakley.com, MauiJim.com, or the Randolph Engineering site guarantees authenticity and opens up custom tints and engraving that resellers do not stock.
Walmart.com
The widest cheap selection online, with a vision center catalogue running into the thousands and plenty under 15 dollars. Licensed pairs such as the Ray-Ban Warrior show up here, and free shipping starts at 35 dollars.
Returns and Buyer Protection for Sunglasses
Return windows decide more purchases than buyers admit, because fit is the one thing a product photo cannot tell you.
| Retailer | Standard window | Requirement | Practical note |
|---|---|---|---|
| Amazon | 30 days | Original packaging | Third-party sellers set their own terms, often shorter |
| Walmart | 90 days | Receipt or order history | Online orders can go back at the service desk |
| Costco | Member satisfaction guarantee | Membership card | Rx work has separate terms, ask the counter |
| Warby Parker | 30 days | Original condition | Return shipping is free on non-Rx orders |
| Sunglass Hut | Varies, check the policy page | Receipt | In-store returns clear faster than mail-back |
Return policies verified July 2026. Confirm on the retailer’s own policy page, since holiday windows and clearance items often differ.
The trap is marketplace stock. A pair bought from a third-party seller on Amazon or Walmart.com follows that seller’s terms, not the platform’s, and that is exactly where counterfeits live. Unsure about fit? Buy from the longest window first. Our roundup of stores with the best return policy goes deeper.
Our Top Sunglasses Picks
Five picks, ranked on ultraviolet rating first, then clarity, build quality, and value against the rest of that tier.
Best overall: Ray-Ban Classic Aviator RB3025. The teardrop metal frame introduced in the late 1930s, still sold with G-15 green, gradient, and glass lens options. It flatters a wide range of face shapes, which is why it has outlasted every trend since. Around 180 to 220 dollars. Check current pricing.
Best budget: Knockaround Premiums. Under 35 dollars, with a spring loaded hinge and a build durable enough to keep one pair in the car and another in the beach bag. Con: coatings wear faster than glass. See the range on Amazon.
Best for water and snow: Maui Jim Peahi. Glass optics with Maui Jim’s PolarizedPlus2 treatment, which is why anglers and boat owners keep rebuying them at 250 to 320 dollars. Heavier on the nose than plastic. See the listing.
Best for sport: Oakley Holbrook. An O Matter frame with Prizm lens tuning built for contrast on trail, slope, and water, in a squared shape that reads casual off the bike. 130 to 200 dollars depending on tint. View sport colorways.
Best designer value: Warby Parker Haskell. Hand-polished acetate in a squared-off retro silhouette, sold with sun lenses from around 95 dollars and offered with an Rx. Free home try-on removes the guesswork.
Building out the rest of a warm-weather kit? See our guides to running shoes, wallets, and backpacks. If you use a tanning bed, tanning goggles are a separate buy, since ordinary sunglasses do not seal against the face.
Start with the tag. If a pair of sunglasses does not state 100 percent UVA and UVB protection, put it back no matter what the price says. Then try it on in person, and if you cannot, order from a retailer whose return window gives you a real second chance.
Common Questions About Sunglasses
What is better, UV or polarized sunglasses?
They solve different problems and are not alternatives. Ultraviolet blocking is a safety feature every pair should have. Polarized filtering is a comfort feature that strips reflected glare off flat surfaces. Plenty of expensive designer eyewear is only the second. Forced to choose, take the ultraviolet rating.
Who has the best cheap sunglasses?
Under 35 dollars, Knockaround, Goodr, and SUNGAIT carry the review volume on Amazon, and Walmart’s own labels handle the under-15 tier. What you give up is coating life and hinge durability, not necessarily sun protection. If a listing states no ultraviolet rating, move on.
How do I pick a frame for my face shape?
Match by contrast, not similarity. Round and oval faces carry rectangular or squared shapes well, angular faces soften under round or aviator sunglasses, and a narrow face needs a shorter bridge more than a small silhouette. The width should roughly match the widest part of your face.
Can I order prescription glasses online?
Yes, and it usually costs less than a vision chain. Warby Parker, Zenni, EyeBuyDirect, and most manufacturer sites accept a current prescription plus your pupillary distance, the millimetre gap between pupils an optometrist measures. Complex progressives are the exception. Vision insurance sometimes reimburses part of a tinted Rx order even when it does not cover the pair.
Do kids need eye protection too?
Yes, arguably more than adults. A child’s eye passes more ultraviolet light to the retina, and children spend more waking hours in direct sunlight. Choose impact-rated polycarbonate with a stated UV400 rating and a snug temple fit, because a pair that lives in a pocket protects nothing.
