The truth about sunglasses

If your sunglasses spend more time on your head than on your face, this one’s for you!

There are many spec-tacular (sorry, we had to!) benefits to wearing your sunnies. As well as adding a fashionable touch to any outfit, they also protect your peepers from the damaging effects of the sun's UV (ultraviolet) rays. 

Want to get totally clued up? We’ve created a sunglasses cheat sheet to help you get to grips with the facts.


Children should wear sunglasses

Thought your little one didn’t need sunnies? Quite the opposite! Children’s eyes are particularly prone to sun damage because they have larger pupils and clearer lenses, which allow more UV to get in.

From tiny tots to teens, make UV protection a family affair with our range of kids’ sunglasses. 


UV light can cause long-term damage to your eyes

Exposure to UV light can make you more likely to get cataracts (that’s the fancy term for a gradual clouding of the lens which leads to blurry vision) or age-related macular degeneration (AKA a gradual loss of vision in the centre of your eye).


Lenses with a darker tint don't necessarily provide more UV protection

Newsflash! Just because the lens appears darker, doesn’t mean it offers better protection.

In fact, wearing sunnies with dark lenses without enough UV protection can actually be worse than wearing no sunglasses at all. Why? Because they can cause the eyes’ pupils to dilate (get bigger) and let more harmful light in.


All sunglasses don't offer the same UV protection

Those sunnies you bought on holiday for $1? Yep, chances are they’re not providing enough UV protection.

The level of UV protection provided by sunglasses can vary from pair to pair, but you can rest assured that at Boots Opticians all our sunglasses meet the International Standard of ISO 12312-1:2013 (en). You’ll look great and feel safe.


You still need sunglasses when it's cloudy

Don't let those clouds fool you! The sun's rays can be just as tough on your peepers when it's overcast. In fact, cloud cover only reduces the amount of UV light by 10 percent. Yep, 10!


You still need sunglasses in the winter sun

Gloves? Check. Scarf? Check. Sunglasses? Huh…?

It may be -2°C outside, but that doesn’t mean you should leave those shades behind. Why? Because the sun's rays are still strong even when the sun sits lower in the sky.


Polarised lenses don't offer extra UV protection

Although they don’t offer extra UV protection, polarised lenses certainly have their benefits.

As well as reducing glare on flat and shiny surfaces, they can help increase contrast, leaving you with comfortable, clear vision on sunny days.

Whether you spend a lot of time driving, fishing, cycling or skiing, you can add polarised lenses to your sunglasses for as little as an additional £70 at Boots Opticians.


Tinted lenses don't offer extra UV protection

Although it won’t affect the level of UV protection, adding a coloured tint can help reduce eye stra
