EyeProtect

schützen Sie Ihre Augen für einen gesunden Schlaf

Do you have problem falling asleep ? Are you using your smartphone or tablet late evening or late night , does your eyes feel tired reading on the phone ? " Eyeprotect - blue light filter " may be a solution for you!

The cause is your eyes photoreceptor, called Melanopsin . This receptor is sensible to a narrow band of blue light between 460nm-480nm, this range can repress the production of a hormone responsible for your sleep-wake cycles health, called melatonin.

While light of any kind can suppress the secretion of melatonin, blue light at nights does so more powerfully.

The bluelight suppressed melatonin for about twice as long as the green light and shifted the rhythm by twice as much (3 hours. vs. 1.5 hour).

What you can do ?

- Use dim redlights at darkness. Redlight has the least power to suppress melatonin.

- Avoid looking at bright screens beginning two to three hours before bed.

- Expose yourself to lots of bright light during the day, which will boost your ability to sleep at night, as well as your mood and alertness during daylight.

- If you work a night shift or use a lot of electronic devices, consider wearing blue-blocking glasses or installing our app that filters the flux of blue light emitted by your phone or tablet and protects your eyes with a soft and pleasant red filter.

Examples of associated scientific research:

Everyone has slightly different circadian rhythm, but the average length is 24 and one-quarter hours.

The circadian rhythm of people who stay up late is slightly longer, while the rhythms of earlier birds fall short of 24 hours.

Harvard Medical School showed, in 1981, that daylight keeps a person's internal clock aligned with the environment.
