While our DefenderShield lenses protect your eyes from damaging blue light day and night, you will notice an improvement in eye strain that can result in headaches, fatigue, dry eyes, and problems focusing.

We have ergonomically developed our unisex blue light blocking Fitover frames as lightweight and slim as possible to be used in conjunction with prescription or reading glasses for the most comfortable fit imaginable. With DefenderShield® Blue Light Blocking Glasses, you can feel confident that the negative effects of long-term exposure to harmful blue light are reduced.

Effects of LED Blue Light on Health

The human body has a biological clock called the circadian rhythm. At night, blue light affects this natural rhythm and sleep suffers. Research also shows that it may contribute to the causation of:

  • Cancer
  • Diabetes
  • Heart disease
  • Obesity

While light of any kind can suppress the secretion of melatonin, blue light at night does so more powerfully. Harvard researchers and their colleagues conducted an experiment comparing the effects of 6.5 hours of exposure to blue light to exposure to green light of comparable brightness. The blue light suppressed melatonin for about twice as long as the green light and shifted circadian rhythms by twice as much (3 hours vs. 1.5 hours).
