With the sun coming out it is more important than ever to keep your eyes protected, but with so manysunglasses out there how do you know which ones to pick?
First of all you need to remember that, like with your skin, the sun can do a lot of damage to your eyes so you need to give your eyes the level of protection they need. So, the first step when picking out your next pair of sunglasses is to check they have a high level of protection against UVB rays at least 99% is recommended by the professionals.
UVA rays can also be dangerous to your eyes so make sure the level of protection is at least 95%. If the sunglasses you’ve picked up are labelled as cosmetic, or do not give you any information, put them down and walk away; they will do as much to help protect your eyes as water helps protectyour skin!
Once you’ve found the sunglasses with the right level of protection it’s important to pick the right colour of lens (like the ones you can find at www.getlenses.co.uk) for you and the activities you want to undertake while wearing them. The colour of lenses you pick can help you detect contrast and differentiate between colours.
Some sunglasses have lenses that enhance contrast but these often mean that colour distinction is lost, which can be a problem if you’re driving. However, some sunglasses do come with interchangeable lenses to allow the colour lenses to be changed easily to fit in with what you’re doing.
Another important aspect of sunglasses that is often forgotten is the material used for the lenses. As with normal glasses, sunglasses that are scratched or have chips in them are worse than useless. If worn they can be dangerous as you can miss obvious things in your immediate vision. Lenses that are made from NXT polyurethane are impact-resistant as well as flexible and lightweight, however they are expensive.
The other options out there are glass, though this is heavier and will spider if broken; it can also be expensive. Polycarbonate is more affordable but is not as scratch resistant nor does it provide as much optical clarity.
