Blue Light Defense is the Best Pair of Glasses I have ever had!


Thanks to listening to one of Dr. Lange’s  radio shows I am wearing the most amazing pair of glasses I have ever had. I have worn progressive lenses for the last 20 years and they have all been pretty good but the new Blue Light Defense progressive  (I think they are called  Blue Defense Extreme)  I have had for a few months is amazing.  I am on a computer 8 hours  a day at work and then another three hours  at home.  My eyes feel much less strained now since I have these new lenses. The biggest benefit I have found is I am sleeping much better since I have been wearing these new glasses.  I have read up on the science behind these lenses and how they block the harmful blue light coming from my computer and daily environment. The blue light causes melatonin levels to drop which causes sleep impairment.  Well they are working and I don’t think it is the placebo effect! I highly recommend these lenses to everyone that is working on a computer.  Thanks Lange Eye Care for staying ahead of the times.   Elizabeth Mack
