What to know about blue light screen protectors

Living in the digital age means people use their electronic devices, including phones, tablets, and computer screens, for extended periods. With this in mind, companies are now selling blue light screen protectors that reportedly block blue light and may benefit eye health.

In 2020, the COVID-19 pandemic and the need for social distancing led to record numbers of virtual events, conferences, and online classes, which further increased people’s use of digital screens.

There has been much debate about how the blue light from screens may affect human health. Currently, there have been no firm conclusions about how blue light may affect a person’s eye health in particular.

The American Academy of Ophthalmology (AAO) states that blue light-blocking glasses or products are unnecessary when using digital devices, such as computers, as causes of digital eye strain are due to lack of blinking or eye moisture.
