Sunglasses: paying 140 euros for what costs 5
A pair of sunglasses with polycarbonate lenses and a UV400 filter can cost 5 euros delivered to your door, or 140. The difference, according to the material circulating in a May 2014 discussion among entrepreneurs, is not in the lens. It's in the brand. The trigger was a purchase: a pair of Hawkers «diamond black - sky one» for 25 euros, with a 10% discount code, rather than risk a pair of 140 euro polarized Ray-Bans on the sand. The argument that trinc —and which is broken down here— is that the frame is the same plastic and the lens, the same polycarbonate.
What's the difference between a polycarbonate lens and a glass one
As argued in the debate, polycarbonate filters ultraviolet radiation on its own up to 400 nanometers, the UV400 standard, without any additional treatment. It weighs less, resists impacts —it doesn't break easily— and takes tints and polarization more easily than mineral glass. Its limits: it scratches relatively easily and has the lowest visual aberration index of the organic materials, which can affect sharpness at the marginal angles of the field of vision.
Mineral glass, on the other hand, requires more millimeters for the same effect, weighs more, is more fragile and needs a specific treatment to block UV. The conclusion drawn in the discussion is uncomfortable for the industry: if the lens material is equivalent, the markup of 100 euros or more is not technically justified. You're paying for the brand, the distribution and the shop window.
Why some sunglasses cost 5 euros and others 130
The direct comparison in the material is between a pair of Hawkers and a pair of Oakley Frogskins: same plastic frame, lenses with no visible difference to the naked eye, both polarized. Four times the price. The calculation used in the conversation is that the product leaves the factory at around 5 euros, with 3.85 euros in shipping and 1.15 in handling. The margin for a reseller selling them at 20 euros is one or two euros per pair.
That's where the real business lies: not in the lens, but in volume and logistics costs. A seller advertising «guaranteed quality» with UV filter checks at home competes against a brand billing the same with an image campaign. The question hanging in the air is whether the consumer is paying for sun protection or for the story.
The real problem: glasses without UV protection sold as sunglasses
Not all of the cheap market is equivalent. The same material documents a specific case: a round model with a black frame, aesthetically superior, which when passed through a UV ray detector gives a reading of 0 nanometers. In other words, it doesn't filter. Its «sisters» with white frames, of poorer finish, do protect.
The finding dismantles the simple equation that cheap equals good. The only reliable check is to run the glasses through a UV meter, something an individual can do at home with a tester. Without that control, the buyer is purchasing blind. And a dark lens without a UV filter is worse than wearing nothing: it dilates the pupil and lets in more radiation.
What to look for before buying cheap sunglasses
For beach use, the criterion defended is to prioritize category 3 solar filter, UV400 protection and a low price, because sand and water guarantee scratches or loss. The frame matters less than the lens. CR39 material, with a 99% visual perspective ratio, appears as an intermediate option between polycarbonate and mineral glass.
The market offers aviator and wayfarer style models with CR39 lenses, UV400 and polarization for 15 euros, with discounts for buying two. The real range goes from the 3 euros of the bazaar to the 140 of a premium brand. In between, almost everything is the same thing with different packaging.
The question is not whether a 5 euro pair of glasses protects as well as a 140 euro one. It's whether the buyer is willing to pay 135 euros to avoid checking for themselves what they're buying. With a UV meter involved, the answer becomes uncomfortable for half the industry.
