Sunglasses : Make the choice to protect your eyes

One of the primary misconceptions about sunglasses is that their central function is to see less light, and though reducing glare and squinting less are important to your overall comfort, that is not in fact the primary reason for wearing sunglasses.

Rather, from a licensed optician perspective, the primary reason is to protect your eyes from the sun’s UltraViolet radiation. This harmful radiation damages the internal ocular structures of the eye and is made all the worse by the fact that a tinted lens – a sunglass lens – actually causes the pupil to dilate or open further. When the pupil dilates it actually allows more of this harmful radiation into the eye itself resulting in potentially even greater damage.

So, you may be asking yourself which sunglasses will best protect my eyes from this harmful UltraViolet radiation? With any sunglasses you intend to purchase you need to ensure that it blocks between 99% to 100% of UVA and UVB rays from the sun. If this is not specified, you should not purchase the sunglasses as you are putting your vision care at risk. When in doubt, your licensed optician will be able to help you choose a pair that fits your needs and meets all the necessary requirements.

With that out of the way, let’s take a few minutes to answer a few of the most often asked questions about sunglasses.
