Are recycled plastic sunglasses good quality? How to judge any pair

Short answer: Recycled plastic sunglasses can be every bit as good as sunglasses made from new plastic. Quality doesn't come from the "recycled" or "new" label; it comes from the specific material, the lenses, the hinges and screws, the finish and the fit. Judge the pair, not the label – the checklist below works on any sunglasses in a couple of minutes.

What makes a good pair of sunglasses?

Four things: lenses that protect and don't distort, a frame that keeps its shape, hinges and screws that stay tight, and a fit that's comfortable for hours. Brand, price and material type only matter as far as they affect those four.

How do you check the lenses?

• Protection: look for UV400 (or 100% UV protection), a category number and the CE mark. Our guide explains what UV400 and category 3 mean.
• Distortion: hold the sunglasses at arm's length, look at a straight line – a door frame or a shelf – and move them slowly. If the line bends or wobbles, the optics are poor.
• Even tint: both lenses should be the same colour and darkness, without patches.
• Surface: no scratches, bubbles or hazy spots.

How do you check the frame and hinges?

• Hinges: open and close the temples. They should move smoothly and hold their position, with no play. Multi-barrel hinges spread the load better than a single barrel.
• Screws: screws with a locking element are less likely to work loose over time.
• Temples: a metal core inside plastic temples adds strength and lets an optician adjust the fit.
• Finish: run a finger along the edges. You shouldn't feel sharp mould lines, rough seams or uneven polishing.
• Symmetry: put the sunglasses on a table upside down – both temples should touch it.

How should good sunglasses fit?

They should sit level, not pinch at the temples and not slide down your nose when you look down. Your eyes should be roughly in the middle of the lenses. Weight matters too: a heavy frame with a narrow bridge will leave marks. If you're unsure which shape and size to pick, our face-shape guide helps.

Are recycled plastic sunglasses durable?

Durability depends on which recycled plastic is used, how it's processed and how the frame is designed – exactly as with new plastic. Some recycled engineering plastics are chosen precisely because they're strong and flexible. What you should expect from any brand is transparency: which material, which parts, and what warranty backs it up. If it's cheap sunglasses you're weighing up, we've also written about what you actually pay for.

What goes into ECO SHADES frames?

Here's what our product and materials pages list for the recycled sunglasses range:

• Frame: 100% recycled plastics – rPCTG fronts and temples in recycled cellulose propionate (rCP). Selected sport styles such as Grosso Black Grey are made from recycled TR90, known for being light and flexible.
• Temples: a stainless steel core in each temple for strength and adjustment.
• Hinges and screws: 5-barrel optical hinges secured with friction-lock screws. Each screw has a nylon patch to stop it loosening – no glue needed.
• Lenses: 100% recycled PMMA, listed as certified UV400.
• Skin contact: listed as hypoallergenic, BPA-free and nickel-safe.
• Warranty: 2 years.

See it in practice in the rectangular Gallina Olive with its wide temples, the cat-eye Palma Black or the softened-square Lodi Blue. For active days, browse our sport sunglasses; if you prefer the depth of acetate, see our plant-based acetate sunglasses.

How do you make sunglasses last?

• Put them on and take them off with both hands, so the hinges don't twist.
• Keep them in their pouch or case, and never put them down lens-first.
• Don't leave them on the dashboard or in a hot car – heat can deform plastic frames.
• If a hinge feels loose, have it tightened before it gets worse.

FAQ

Are recycled plastic sunglasses as strong as regular ones?

They can be. Strength depends on the specific material and the design, not on whether the plastic is recycled. Check the hinges, screws and warranty.

How can I tell if sunglasses are good quality in a shop?

Check for UV400 and a CE mark, do the straight-line test for distortion, open and close the hinges and feel the edges for rough seams.

Does a higher price mean better quality?

Not necessarily. Price often reflects brand and retail costs. Judge the lenses, hinges, finish and warranty instead.

How long should a good pair of sunglasses last?

With reasonable care, many years. Look at the warranty as a minimum signal of what the maker stands behind.
