DefenderShield® Flex Blue Light Blocking Glasses block harmful blue light to help reduce the negative health effects of computer and mobile device screens. Our superior quality lenses filter from 50% up to 99% of blue light that can cause digital eye strain, premature eye-aging, and interfere with sleep.

DefenderShield® Flex Blue Light Blocking Glasses are the ultimate solution for protecting your eyes from blue light emitted from digital screens of computers, laptops, tablets, cell phones and other electronic devices. 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.

While wearing our professional and polished frames, you can feel confident that the negative effects of long-term exposure harmful blue light are reduced. We have ergonomically developed our unisex blue light blocking glasses for the most comfortable fit imaginable.

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).
