Our Mood Booster glasses combine colour therapy and blue blocking technology to bring you our SummerGlo lens, a holistic and powerful way to overcome low mood, depression, anxiety and seasonal affective disorder. The warm yellow lens depicts a sunny summer’s day offering uplifting benefits whilst the blue light blocking technology blocks 100% of artificial blue light from 400nm – 450nm, the frequency known to contribute to depression. These daytime blue light blocking glasses deliver optimal results when combined with our evening wear Sleep+ blue and green blocker glasses. *All our glasses are unisex and come in Prescription, Non-Prescription, and Readers.
