“Blue light blocking glasses matter because we all need better sleep,” says Connecticut-based behavioral optometrist Dr. Juanita Collier.
The infamous blue light from countless hours spent in front of a smartphone, computer screen, tv, etc. suppresses the production of melatonin - the main hormone that promotes and regulates sleep.
She notes that blue light’s damage can extend well beyond sleeping issues. Prolonged screen time can exacerbate eye teaming difficulties (how the eyes work together), depth perception issues, and cause dry eye. Studies also show blue light increases tumor growth, while melatonin can decrease tumor growth.
