Common Sunglasses Myths Debunked
There's a lot of misinformation about sunglasses floating around. Some of these myths are harmless; others could be genuinely putting your eyes at risk. Let's set the record straight on the most common ones.
Myth 1: "Darker Lenses = Better Protection"
False. Lens darkness and UV protection are completely independent. A very dark lens with no UV coating blocks visible light (making you comfortable) while letting UV radiation pass straight through to your dilated pupils. UV protection comes from the lens coating, not the tint. Always check for UV400 certification regardless of lens colour.
Myth 2: "You Don't Need Sunglasses on Cloudy Days"
False. Up to 80% of UV radiation penetrates cloud cover. Clouds reduce visible light (so it doesn't feel bright), but UV still reaches your eyes. This makes overcast days particularly risky because you're less likely to wear protection even though significant UV exposure is occurring.
Myth 3: "Expensive Sunglasses Are Always Better"
Partly true, partly false. Price alone doesn't guarantee quality — some expensive designer sunglasses are overpriced for what they deliver. What matters is the specifications: UV400 protection, quality polarisation, and durable frame materials. A well-made pair at $180 can outperform a designer pair at $500 if the specs are better.
Myth 4: "Polarised Lenses Block UV"
Not necessarily. Polarisation and UV protection are different technologies. Polarisation filters glare (horizontally-oriented light). UV protection blocks ultraviolet radiation. You can have polarised lenses without UV protection, or UV protection without polarisation. The best sunglasses have both.
Myth 5: "Kids Don't Need Sunglasses"
Absolutely false. Children's eyes transmit more UV to the retina than adult eyes because their lenses are clearer. Up to 80% of a person's lifetime UV exposure occurs before age 18. Getting kids into quality sunglasses early is one of the best things you can do for their long-term eye health.
Myth 6: "All Sunglasses Sold in Australia Meet Australian Standards"
False. While there are regulations, enforcement isn't perfect. Sunglasses sold through unregulated channels (online marketplaces, markets, pop-up shops) may not comply with AS/NZS 1067.1. Always buy from reputable sources that clearly state their compliance.
Myth 7: "Sunglasses Last Forever"
Depends on the quality. Cheap sunglasses degrade relatively quickly — UV coatings can deteriorate in 1-2 years, and frames fatigue and break. Quality sunglasses with durable materials and coatings last much longer. Carbon fibre frames like the Voyager Black are effectively permanent — which is why they come with a lifetime warranty.
The Bottom Line
Don't let myths guide your eyewear choices. Focus on verified UV400 protection, quality polarisation, comfortable fit, and durable construction. Your eyes are too important for guesswork.
