What are blue light lenses?

If you look at digital screens like computers, mobiles and TV, your eyes may be exposed to blue light. This isn’t always harmful to your eyes or vision; however, it can affect your sleep and may cause digital eye strain.

Blue light glasses help filter blue- violet light, which may minimise their effects and can help to improve sleep.

How do blue light glasses work?

The lenses in blue light glasses may have a subtle tint, which helps to counterbalance and filter blue-violet light. They filter blue-violet light just like sunglasses filter UV rays. This means your sleep could remain unaffected even when you use digital devices.
