A reader asks:

 Are there contact lenses available that perform the same function as the blue-blocker glasses you recommend on your online store?


While tinted contacts have been around for years, none replicates the specifications of the Photonic Developments’ protective lenses. These protective lenses are used to assist sleep onset, to allow evening melatonin to exert its circadian rhythm shifting effect, and — in the most recent research — to calm hypomanic and manic symptoms of bipolar disorder.  Contacts are a good idea, and we will look into this possibility for future development. Thanks for asking!
