Scrolling through our mobile phones is a part of our daily lives. Frankly, we are not just using them for entertainment. In the modern world, we use them for new information, calculators, calendars, personal diaries, and many more. As they become a part of our lives, we forget they emit harmful blue light.

What is Blue Light?

Let’s see how exposure to this simple light can lead to harmful results. It is a High-Energy Visible (HEV) light visible to the human eye. As the eyes cannot filter this light, it can penetrate the retina.

The Effects of Prolonged Light Exposure

Dry eyes

This is one of the common effects of blue light. It occurs when our eyes do not produce enough tears for lubrication and nourishment. Common symptoms include blurry vision, red eyes, sensitivity to light, watery eyes, and a stinging sensation.

Sleepless Nights

Blue light keeps us awake because it messes with melatonin, the hormone that helps regulate our body’s cycle. It is also one of the factors why our eyes feel tired.

Cataract Growth

Blue light can penetrate our cornea, lens, and retina, as our eyes are not efficient at blocking it. Unfortunately, this action can lead to the growth of cataracts, a type of eye problem that may cause blindness in the long run.

Light bulbs also emit blue light; thus, we are exposed to light beams even without facing a digital screen. Sadly, due to a lack of knowledge regarding lenses, most of us brush off the importance of wearing protective eyewear. This includes eyeglasses with blue lens UV420 and multicoated lenses. Unknown to many, blue lens UV420 blocks blue light and reduces eye strain.

On the other hand, multicoated lenses are scratch-resistant, anti-glare, and have UV protection. So, these lenses are perfect for people with smartphones, laptops, and tablets.

What an EO Patient Says

“My work involves a lot of screen time. Because of this, I’ve decided to purchase eyeglasses with blue lens UV420, so my eyes will be protected from blue light. Luckily, it has helped prevent the possible progression of an eye-fatigue.”

Thus, it may seem like a hopeless case since artificial light is everywhere, but there are things you can do to prevent eye strain from excessive exposure to blue light.

Tips to Protect Your Eyes from Blue Light Exposure

Tips to prevent blue light exposure
  • Cut down on screen time and follow the 20/20/20 rule. Take a 20-minute break from your gadget and stare at an object 20 feet away for 20 seconds.
  • Let your eyes rest as this may affect the production of sleep hormones.
  • Switch on night mode on your phone or tablet.
  • Buy eyeglasses with a blue lens (UV420) that blocks blue light from your gadget.

Thus, invest in your eyes to avoid a costly consequence. You may also check out EO’s stylish eyewear with anti-radiation or multicoated lenses with protection and style in one frame.
