Let’s face it, many of us often at use our mobiles, TV screens or laptops for hours before switching off the light and then trying to go to sleep. Whilst there are the lucky ones who can sleep anywhere and at any time, many of us struggle with insomnia, which has many other knock-on negative health effects.
One reason why using digital devices before bed-time is detrimental to sleep, is because the screens emit High Energy Visible (HEV) light, which we see as the colour blue. This is the same light which is emitted most by the mid-day sun. When we are exposed to this spectrum of light, our brains think it must be the middle of the day, and therefore need to be switched on and alert. When we are exposed to HEV light for 2-3 hours before bed time, we trick our brains into thinking it is the middle of the day, which can causes havoc with our circadian rhythms by suppressing melatonin levels in our brain, and prevents us falling asleep naturally and getting a good night’s rest.
Computer Glasses solve this problem by blocking the HEV light, and wearing them for 2-3 hours before switching off at night can really help those who suffer from insomnia.
If you suffer from Insomnia when using your digital screens, then we would recommend our Heavy Duty lens, which blocks out 98.5% of all HEV light, offering you maximum protection, shielding your eyes and brain allowing you to get a good night’s sleep.
