If you have an extra pair of glasses, send them to an online eyewear retailer to make sure the lenses have the correct 'visual center.' Measure the pupil distance.

Wear blue light glasses before bed.

Because blue light can have a huge impact on your sleep cycle, these glasses are pretty important before bed. So, putting on blue light glasses before you go to bed can help increase melatonin, which in turn helps you get a good night's sleep. Sleep glasses display a wider range of blue light, which naturally helps you sleep better and triples melatonin production. They have a slight lens color because they target a wider range of light, but are best for sleeping. In addition to sleep glasses, there are nearly transparent optical glasses that filter out blue light levels to help treat digital eye strain, which is made up of headaches, blurred vision, and eye strain.
