The Hidden Dangers of Cheap Sunglasses
A pair of sunglasses for $10 sounds like a bargain. But when it comes to your eyes, cheap can be genuinely dangerous. Here's why those budget sunnies might be doing more harm than good.
The Dark Lens Trap
This is the most important thing to understand about cheap sunglasses: dark lenses without proper UV protection are worse than wearing no sunglasses at all.
Here's why: when you put on dark lenses, your pupils dilate to let in more light. This is your eyes' natural response to a darker environment. If those dark lenses aren't blocking UV radiation, your dilated pupils are now letting in MORE harmful UV rays than if you'd worn nothing at all.
It's a cruel irony — the sunglasses you bought to protect your eyes are actively increasing UV exposure to your retinas.
Australian Standards: AS/NZS 1067.1
Australia has one of the world's most rigorous sunglasses standards: AS/NZS 1067.1. It covers:
- UV transmittance — How much UV radiation passes through the lens.
- Lens category — Rated 0-4 based on how much visible light is transmitted.
- Optical quality — Ensuring lenses don't cause distortion.
- Durability — Frame and lens resistance to normal wear.
Legitimate sunglasses sold in Australia should comply with this standard. The problem? Many cheap, imported sunglasses don't — and enforcement is patchy.
What Cheap Sunglasses Skip
To sell sunglasses at rock-bottom prices, manufacturers cut corners on:
- UV coatings — The cheapest route is dark-tinted plastic with no UV filtering at all.
- Optical quality — Poorly ground lenses cause distortion that leads to eye strain and headaches.
- Polarisation — Many cheap "polarised" sunglasses aren't actually polarised, or use such low-quality polarisation that it's ineffective.
- Frame durability — Cheap plastic cracks and breaks within weeks, creating a cycle of constant replacement.
The True Cost of Cheap
Let's do some quick maths. If you buy a $15 pair of sunglasses four times a year (because they keep breaking), that's $60 per year. Over five years, you've spent $300 on sunglasses that never properly protected your eyes.
A quality pair like the Voyager Black costs $179.99 once and comes with a lifetime warranty. It provides genuine UV400 protection, real polarisation, and a crushproof carbon fibre frame that doesn't need replacing. The maths speaks for itself.
How to Spot Quality
When shopping for sunglasses, look for:
- Specific UV claims — "UV400" or "100% UV protection" is what you want. Vague claims like "UV resistant" are red flags.
- AS/NZS 1067.1 compliance — Check the label or product listing.
- Lens category rating — Category 3 is ideal for most Australian outdoor conditions.
- Brand reputation — Buy from brands that stand behind their products with meaningful warranties.
Invest in Your Vision
Your eyes are irreplaceable. The damage from UV exposure accumulates silently over years, and by the time you notice symptoms, significant harm has already been done. Don't gamble your vision on a $10 pair of sunnies. Browse the ShadyMate Voyager range and invest in protection that actually works.
