No. Blue light glasses are not harmful. They filter out blue light, which makes your eyes feel tired. There are also sunglasses with other color filters, so you can find the right pair to protect your eyes.

We recognise that it can be easy to simply huff and puff on your lenses before wiping them "clean" on your shirt when you're out. But rather than cleaning the dirt off the glass, you will simply scratch your lenses by doing this.

So, when sunglasses  become smudged or dirty, clean them with a liquid lens cleaner using a soft, lint-free cloth.
