Protect your eyes from blue light in our digital world

In today’s digital age, we spend hours each day staring at screens—laptops, smartphones, tablets, and more—that emit potentially harmful blue light. Prolonged exposure to this light can negatively affect your eye health and overall comfort. A simple and effective way to protect yourself is by wearing glasses with a blue light filter, even if you don’t normally need prescription lenses.

What is blue light?

Blue light is a visible part of the light spectrum with a short wavelength that carries more energy than other colors. Exposure to artificial blue light stimulates photoreceptors in the eyes and affects the pupillary reflex, which delays the production of melatonin—the hormone responsible for regulating sleep.

Using screens late into the evening can disrupt your body’s natural biorhythm, leading to poor sleep quality, tired and dry eyes, redness, light sensitivity, and even headaches. If you often work late, browse in bed, or play games at night, blue light filter glasses can provide real relief.

Practical tips to reduce blue light exposure

  1. Take breaks and maintain distance
    Regularly look away from your screen and focus on something far away to relax your eyes.
  2. Adjust screen brightness
    Lower your screen brightness in darker environments to reduce eye strain.
  3. Enable blue light filters on devices
    Most smartphones, tablets, and computers have built-in blue light filters—make sure to activate them.
  4. Use special software
    Programs like Iris or f.lux adjust your screen’s color temperature automatically based on the time of day, reducing blue light emission.
  5. Use Night Shift mode on iOS
    This mode warms up your screen colors in the evening, limiting blue light exposure.
  6. Wear blue light filter glasses
    Even if you don’t need corrective lenses, blue light filter glasses can protect your eyes during extended screen time.

What are blue light filter glasses?

These glasses feature a special coating on the lenses that blocks harmful blue light, helping prevent eye strain and sleep disruption. They are beneficial for anyone who spends more than two hours a day in front of screens.
