5 top tips for buying the right sunglasses

Posted On 30 March 2012

If you're lucky enough to be holidaying abroad this year, alongside packing your suntan lotion, travelers cheques and a good book, have you stopped to consider what eyewear you’ll need to keep your eyes safe in the sun?

Protecting your eyes from the sun’s UV rays is essential. We are all aware of the impact the sun has on skin, but tend to be less clued up about our eyes. The truth is that exposure to UV rays from the sun has been linked to eye conditions such as cataract. Sunglasses are not just a great fashion accessory; they’re there to serve a very functional purpose of filtering out harmful UV rays.

Unfortunately there are a lot of sunglasses available which do not offer the levels of protection required to keep your eyes safe, and determining which pairs offer protection and which don’t, can prove tricky. Luckily Tesco Opticians is here to help with a quick 5 point guide to buying the right sunglasses for going abroad this summer.

1. Choose sunglasses that block both UVA and UVB rays. It should say on the lenses whether this is the case – look out for either UV400 or 100% UV Protection on the label.

2. Wrap around styles are best for fully protecting the eyes from those harmful rays (also ideal for comfort if you play a lot of outdoor sports)

3. Consider polarised lenses – these not only block out UV but also reduce glare, offering clear, crisp vision. 

4. If you normally wear prescription glasses, purchase some prescription sunglasses - you won’t be tempted to take them off when completing certain tasks (i.e. reading) and thus exposing your eyes to the sun. As a bespoke item, prescription sunglasses should also provide the highest level of UV protection, but always double check with the provider. 

5. If your budget (and taste) allows, Ray-Ban is the global leader in sunglasses. Ray-Ban lenses are manufactured using patented technology to ensure the very best protection for your eyes and are highly recommended by Tesco Opticians.

In addition to the above however, it is also very important to remember to wear your sunglasses whenever you are outdoors, especially if you are abroad. Even on cloudy days, or when you’re in the shade, your eyes can still be affected by the sun’s rays. Also, make sure you have regular sight tests; they really are the best way to monitor the health of your eyes.
