Do blue light glasses work?

Blue light emitted by screens can affect our sleep, focus, and eye health. Blue light glasses offer an effective solution to protect yourself from these harmful effects.

What is blue light?

Blue light is a portion of the visible light spectrum, mainly emitted by LED screens such as computers, smartphones, televisions, and tablets. It has a shorter wavelength and higher energy than other visible light, making it especially stimulating for the brain.

Exposure to blue light in the evening can disrupt the body’s natural circadian rhythm, leading to mental fatigue, stress, difficulty concentrating, and sleep cycle disturbances.

Wearing blue blocking glasses or glasses with a blue light filter helps limit these negative effects and supports daily well-being.

How does blue light affect sleep?

Prolonged exposure to screen light in the evening can significantly disturb your sleep. This artificial blue lighting sends a misleading signal to the brain, suppressing melatonin production—the hormone responsible for falling asleep. As a result, many experience insomnia, night-time awakenings, and chronic fatigue.

At INDESmed, we’ve developed a range of blue light blocking glasses to address this issue. Our models include blue light reading glasses, ideal for people with diopter needs (presbyopia), and non-prescription screen glasses for those who want protection without vision correction.

These glasses are equipped with a special filter that blocks a significant portion of harmful blue wavelengths. By wearing them in the evening, you help your body maintain its natural sleep rhythm, supporting a more restful and restorative sleep.

How does blue light affect the eyes?

The blue light emitted by digital devices penetrates deeply into the eye. Daily, prolonged exposure can lead to noticeable effects on visual health.

In the short term, blue light is responsible for eye strain, dryness, burning sensations, and headaches. This is commonly referred to as digital eye strain or computer vision syndrome, which many experience after long hours in front of a screen without proper protection.

Over time, studies suggest a possible link between blue light exposure and serious eye conditions such as early cataracts, age-related macular degeneration (AMD), and disruptions to the pupil reflex.

To protect your eyes, experts recommend wearing glasses with a blue light filter. These are considered among the best glasses for blue light protection, especially for office workers and screen users. For people with diopter needs, blue light reading glasses offer both visual clarity and protective benefits.

By selectively filtering harmful wavelengths, blue light glasses help reduce eye fatigue, improve visual comfort, and protect your long-term eye health.

What do blue light glasses protect you from?

Blue light glasses are designed to filter out the most harmful part of the blue lighting spectrum emitted by screens like smartphones, computers, and TVs. By wearing blue blocking glasses, you can protect your eyes from digital eye strain, reduce headaches, prevent sleep disturbances, and improve overall visual comfort. These glasses with blue light filter are especially useful for people working long hours on screens or those sensitive to artificial lighting. Whether you wear diopter glasses or not, there’s a model adapted to your needs.
