Can I wear Swannies even if I'm not using my gadgets?

We recommend wearing Swannies Blue Light Blocking Glasses any time you’re using digital devices such as phones, tablets, computers or TVs for extended periods. This will prevent digital eyestrain. We strongly recommend wearing your Swannies at least one hour before bed to stop artificial blue light disrupting your sleep. Some customers report better results putting the glasses on even earlier before bed.
