Are blue light lenses worth the cost?

[WCCO-TV, August 12, 2019] Blue light glasses have become increasingly popular for its promise to filter out the blue light that comes from electronic devices. Consumers who buy the special glasses typically see the light itself as harmful, although research indicates the amount of time spent looking at screens, rather than the light itself, may be the bigger culprit.

Allina Health optometrist Dr. Kristi Backer-Palmer emphasizes the research that is still trying to determine how blue light impacts the delicate retinal cells and a possible connection between the light and a form of degeneration that could lead to vision loss over time. She says the short term symptoms—headaches, eye strain, sleeplessness—are common for people who spend a lot of time looking at their devices.
