Blue light damage comes from the sun, digital devices. Here's how to protect your eyes.
A University of Georgia study indicates that blue light from the sun and digital devices can cause eye strain and vision issues due to its high-energy scattering properties. Researchers suggest that individuals with lighter-colored eyes may be more susceptible to these effects.
Why it matters
Understanding the impact of blue light exposure is essential for developing better digital display technologies and personal eye health practices.
