In an increasingly digital world, there’s a strong link between the frequent use of electronic devices and vision concerns. Specifically, it’s the blue light, or the most energetic part of the light spectrum, that has the greatest impact on eyesight. Here's a closer look at vision problems that may require the help of an eye doctor and proactive measures you can take to protect your eyes.

Where Blue Light Comes From

The visible light spectrum refers to anything the human eye is capable of seeing. Blue light has the shortest wavelength of that spectrum, and at least a third of anything you see is considered high-energy visible light

While the most potent source of blue light is the sun, exposure to artificial sources increases your likelihood of experiencing eye problems. Common culprits include computer screens, smartphones, tablets, LED lights, and fluorescent lights. Since so much of modern life involves constant exposure to these sources, blue light has become a more serious concern.

Why It's Harmful

Blue light exposure from screens is limited when compared to the sun, but the risk increases because of your proximity to digital devices—and the amount of time that you use them. The light is beneficial for some reasons, like regulating your natural sleep cycle and helping you stay alert during the day. However, the eyes don’t block blue light effectively. When you’re exposed to this light, it passes through the cornea and lens to reach the retina, which is where light is converted so that your brain can decipher images. 

Frequent exposure to the light may cause damage to the cells in the retina, eventually leading to vision disturbances, cataracts, and age-related macular degeneration. Unfortunately, because kids absorb more blue light than adults from these devices, they are at greater risk as they get older. Additionally, you may experience eyestrain with regular exposure to blue light from digital screens, leading to problems like dry eyes, headaches, and vision blurriness.

How Blue-Light Glasses May Help

Whether you need prescription eyeglasses or not, an eye doctor may recommend glasses that are specially designed to be worn when looking at screens. Their lenses create a barrier that protects your eyes from overexposure to the high-energy light, in the process reducing strain and even helping regulate your sleep-and-wake cycles. 

By blocking the powerful wavelengths, you may also find it easier to use your device for extended periods of time. Ideal candidates for these glasses are people who are exposed to blue light for hours a day at a desk job and who routinely experience eye discomfort.
