Two pairs can look almost identical online and feel completely different on your face. The reason is usually the frame material. PC (polycarbonate), metal and acetate each have their own weight, feel, durability and price. This guide explains what each one is good at, who it suits, and which Augen pairs to try.
The quick answer: choose PC for light, affordable, everyday and sporty pairs. Choose metal for slim, minimal styles that look polished. Choose acetate if you want rich colour, a premium feel and a pair you'll keep for years.


PC (polycarbonate): light, tough and affordable
Polycarbonate is a lightweight, impact-resistant plastic. It's the material behind most everyday and sports sunglasses, because it's light enough to forget you're wearing it and tough enough to survive a bag or a backseat. It's also easy to mould into bold shapes, which is why wraparounds and chunky fashion frames are usually PC.

Try the Breeze (Rs. 649), a futuristic wraparound that weighs next to nothing. For sport, the Kinetic (Rs. 699) stays put on rides and runs. Most of our under Rs. 999 range is PC.
- Best for: daily wear, travel, sports, first pairs and gifting on a budget.
- Keep in mind: PC frames can't be heat-adjusted much, so pick your size carefully.
Metal: slim, minimal and polished
Metal frames use thin wire or sheet metal, often with adjustable nose pads. That gives you a lighter-looking, more refined profile: think aviators, clubmasters and rimless styles. Nose pads also mean a more customisable fit, which helps if pairs usually slide down your nose.

The Shift Sora (Rs. 1,499) pairs gold-tone metal detailing with a rimless photochromic lens for a premium, office-ready look. Want a classic shape instead? The Santorini Clubmaster (Rs. 599) is a metal classic at an easy price.

- Best for: work, smart-casual looks, and anyone who wants a lighter visual weight on the face.
- Keep in mind: thin metal can bend if you sit on it. Always use a case.
Acetate: rich colour and a premium feel
Acetate is a plant-based plastic made from cellulose and cut from layered sheets and polished. That's why acetate frames have deep, glossy colours and patterns like tortoiseshell that look the same all the way through. They feel noticeably more substantial in your hand, and a good optician can heat-adjust them for a better fit.

Most of Augen's acetate styles, including the three below, come with polarized lenses. The Granite (Rs. 2,399) is a bold retro square that suits most face shapes. The Lucent (Rs. 2,399) is a softer round. For a cat-eye in acetate, see the Sable (Rs. 2,699).

- Best for: a long-term "forever pair", gifting, and anyone who loves colour and texture.
- Keep in mind: acetate is heavier than PC and costs more. Don't leave it in a hot car, as heat can warp it.

FAQs
Is acetate better than plastic?
Acetate is a type of plastic, but it's made differently: it's cut and polished from sheets rather than moulded. The result is richer colour, a more substantial feel and frames that can be adjusted. PC is lighter and tougher for active use.
Which frame material is the lightest?
PC is usually the lightest. Thin metal frames can also feel very light, especially rimless styles.
Does frame material affect UV protection?
No. UV protection comes from the lens. Check for "UV Protected" or "UV400" on the product page, whatever the frame.
