270: The Effects of Blue Light on Our Eyes, Skin & Sleep - Dhruvin Patel, Ocushield Founder

On Air with Ella - podcast episode 270

Dhruvin Patel Ocushield


Blue light, like other colors of visible light, is all around you. The sun emits blue light, as do fluorescent and incandescent light bulbs. However, human beings are now exposed to more blue light than ever before because of the widespread use of LED devices (light-emitting diode). Computer screens, flat-screen televisions, cell phones and tablets all use LED technologies with very high amounts of blue light. So, what's the harm?

Almost all blue light passes straight through to the back of your retina, and there’s evidence that blue light could lead to permanent vision changes. Some research has shown blue light may increase the risk of macular degeneration (a disease of the retina), and at the very least, many hours a day in front of our screens causes eye strain and fatigue.... not to mention premature aging of the skin and poor sleep. So, what do we do?

Ocushield Founder & CEO, Dhruvin Patel is sharing:
  • What is blue light and why should we pay attention to its effects

  • What produces blue light?

  • How blue light affects our eyes

  • How blue light affects our skin and premature aging

  • How blue light affects our sleep and what to do about it

  • Blue light and kids - why are the harmful effects worse for children?

Dhruvin is the founder & CEO of health-tech business Ocushield, creator of the world’s first MHRA-registered (and FDA-registered) blue-light blocking screen protectors which mean fresher feeling eyes and improved sleep after screen use. Launching while in his final year as an Optometry student, Ocushield has grown into a 7-figure business in more than 72 countries, and selling to Nordstrom, Best Buy, Sky Mobile and Superdrug.

Dhruvin has been featured in Forbes, Cosmopolitan, USA Today and The Wall Street Journal. His recent pitch on the UK's "Dragon’s Den" (like the US's "Shark Tank") was so compelling that it resulted in an offer from not one but two Dragons, Tej Lalvani and Peter Jones, who went head-to-head for Ocushield's business.
