Summary
A pair of blue light glasses is one of the most worthwhile pieces of technology the author has invested in
They improve focus and mental clarity as well as helping the user sleep better
Blue light is emitted by LED and OLED displays and can induce stress
The best lenses block a proportion of high-energy visible blue light and have anti-glare and scratch-resistant coatings
Look for pairs that block at least 35% of HEV light in the 400–450nm range, have clear or very clear lenses and are lightweight with well-balanced frames
Advanced pairs have additional features such as audio and connectivity built in
