Whether we’re working from a computer, video-calling friends, catching up on the latest episode of a series, or scrolling through social media – our daily screen time is more prominent now than ever. For many of us, that screen time is constantly growing, but what effect does this have on our eyes? As our daily habits shift toward constant exposure to digital screens, this means more work for our eyes, as they struggle to protect themselves from the harmful blue UV light that is emitted from our digital devices.

Blue light is a potentially harmful, high energy visible light that naturally comes from the sun but is also emitted from digital screens. Blue light wavelengths are short, ranging between 380nm and 500nm, meaning they can scatter easily, causing detrimental damage to the eye.
Blue light isn’t all bad. Although it’s widely known that blue light rays are extremely harmful for the eyes, some exposure is necessary in order to regulate circadian rhythm, which improves memory and mood. It’s even more important for children to have exposure to blue light as it helps to maintain healthy eye development.
On the other hand, excessive exposure to blue light can be really harmful to us, severely damaging our eyes and further impacting our health. After a day in front of your computer, you may start to experience dry and irritated eyes, or blurry vision, which is caused by digital eye strain. As a knock on effect of battling this glare, you may experience headaches and start to struggle sleeping (and nobody wants that!). As blue light rays are shorter in wavelength, they can easily penetrate through the retina of the eye, causing premature eye ageing and vision problems in the future.
Whilst it’s impossible to completely eradicate screen time from our daily routine, we can look at ways to reduce our exposure to screens and keep our eyes healthy by opticians essex.
