7 Sunglasses Myths

Let’s separate the facts from marketing spin and dive right into clearing up 7 sunglasses myths in time for spring!

In Queensland, we’re taught from a very young age about how to protect our skin from the sun. Everybody knows that sunglasses protect your eyes from UV rays…but do they? Let’s clear up some common myths about sunglasses then!

Myth 1 – All sunglasses protect your eyes

Unfortunately, there are many sunglasses that do not protect against the sun’s harmful rays. In fact, sunglasses with poor UV protection actually place your eyes at higher risk. This is because they make it darker for your eyes which causes your pupils to open up. Part of the eye’s natural defence is to close your pupils to reduce the amount of light entering the eye. So, it’s important to check your sunglasses protection category. Category 2 and 3 sunglasses provide good UV protection. If in doubt about your sunglasses, come in and ask us to check them over for you. We’ll gladly dispel sunglasses myths!

Myth 2 – More expensive sunglasses are better

It’s surprising how many expensive fashion sunglasses don’t provide adequate UV protection and actually reduce your clarity of vision. Often, the cost is in the frame, fashion or brand name, but the lenses are just basic bits of plastic and not all that sophisticated when it comes to vision and eye protection. The price of sunglasses can be a false sense of security.

Myth 3 – Sunglasses aren’t necessary when it’s cloudy

Even when it’s cloudy, UV rays are still harmful to us. If like me, you’ve ever become sun burnt on a cloudy day, you probably already know this. For this reason, sunglasses should also be worn on cloudy days and if you have to take them off because you can’t see well, they’re the wrong type of sunglasses!

Myth 4 – Darker lenses provide better protection

Fact: the darkness of a sunglass lens tint has nothing to do with the amount of protection provided by the lenses. Lighter-tinted lenses can offer just as much or even more protection than darker ones.

Myth 5 – polarized lenses are better

Number five in our sunglasses myths is only true if the lenses are of prescription optical quality and have a good polarizing filter.  However, polarised lenses don’t automatically provide good protection. Some don’t protect at all and a lot will distort or worsen your vision. Many cheap servo or fishing glasses are polarized plastic films that are bent into a frame which changes the protective and polarizing effectiveness.

Myth 6 – Amber lenses are Better than grey lenses (or visa versa)

Tint colour has nothing to do with the level of UV or glare protection provided by the lenses. We hear this sunglasses myth all the time. Lens colours may have an effect on your vision clarity for specific tasks, but in reality, you can wear any colour so long as it provides Category 2 or 3 UV protection.

Myth 7 – Children don’t need sunglasses

Kids don’t know the difference. If as adults, we need to wear sunglasses, why wouldn’t a child? Their eyes are special, but not because they have magical powers to block UV rays! An estimated 80% of an eye’s exposure to the sun occurs in childhood. It’s therefore, arguably more important for children to wear quality sunglasses than adults.

Clearly, there are many sunglasses myths out there regarding sun protection and sunglasses. Hopefully, we’ve helped clear up the truth for you on some of these myths.
