Blue Blocking Glasses Canada


blue blocking glasses canada are designed to filter out blue light from digital screens, reducing eye strain, dry eyes and headaches. Blue light, when found naturally in sunlight, can help regulate your sleep-wake cycle, but when emitted from digital devices like laptops and tablets it can disrupt your circadian rhythms and make it harder to fall asleep at night. The best blue blocker glasses will be clear, and have a tinted lens that filters out blue wavelengths of 400-500nm while allowing the rest of the spectrum through. Look for spectral transmission data online, and choose pairs that have been created by companies who do the research and create their own products back by science to ensure quality.

While some studies have shown that high levels of blue-light exposure can cause problems like digital eyestrain and eyestrain-induced headaches, the American Academy of Ophthalmology and the American Optometric Association don’t believe that these effects are caused by glasses or other blue-light filtering technologies. They do endorse other strategies to improve your sleep and recommend avoiding screens for an hour or two before bedtime.
