Blue is a favourite colour for many. But did you know that it could cause problems for your eyes?

Blue light is like a close relative to ultraviolet light.

The main difference is that we can see blue light but UV light is not detectable by our eyes

Just like how UV light can give you sunburns, blue light can penetrate deep into your eyes and cause harmful effects.

It is just as important to protect your skin with sunscreen as it is to protect your eyes with sunglasses. 

Sunglasses are more than just a fashion accessory!

Wearing sunglasses outdoors will block out UV and blue light to protect your eyes from developing cataracts and macular degeneration. They also reduce glare to make your sunny day more enjoyable.

We are getting more exposure to blue light now because we are looking at screens for long periods of time.

For better or for worse, digital devices have become a part of our culture. 

Blue light from screens can cause eyestrain. 

Give your eyes a break by following the 20-20-20 rule. Every 20 minutes, focus on an object 20 feet away, for 20 seconds.

Long exposures to blue light interferes with our body’s sleep cycle.

 This will delay the time it takes to fall asleep and it affects the quality of our sleep.
