Phone filter to boost your sleep

COULD a shield for your smartphone be the secret to a good night’s sleep? Mobile phones and laptops emit blue light which blocks melatonin, the hormone that tells the body it’s time to go to sleep, but stimulates the eyes and brain. As a result, heavy screen use is potentially ruining our sleep patterns and our health, warns optometrist Dhruvin Patel.

Concerned by the effect blue light is having on millions of us, he has created a range of special screen shields that filter out blue light.

The Ocushield claims to improve sleep and protect eyes, while maintaining a clear picture and strengthening the screen with tempered glass. From £20, ocushield.com
