Do you need sunglasses for laptop screens?

It’s a common question — do you need sunglasses for your laptop screen? It’s an important question too. After all, the average person spends about five hours on their computer every day.

The answer is that it depends on the type of screen you have. If you have a tablet or a smartphone, then no, you don’t need to wear sunglasses while using it. But if you have a laptop with an LED backlight, then yes, the answer is yes.

How can you tell if your laptop has an LED backlight? Most laptops made after 2012 have some sort of LED backlight, so this answer will apply to most people reading this article. If your laptop was made before 2012, then check whether it uses CCFL (cold cathode fluorescent lamp) or LED backlighting.

The former uses mercury lamps and is not recommended for use in indoor environments because of the toxic risk involved in breaking them; the latter uses LEDs instead and is much more environmentally friendly but requires a different kind of care when broken because they contain mercury as well.

LEDs work by using tiny diodes that produce light when electricity passes through them. They’re just like Christmas lights except they’re much smaller and much more efficient.
