It is important to adopt some damage reduction measures, such as adjusting the brightness and contrast of the computer, tablet or laptop screen. In the case of the latter, you can change the graphics settings to reduce the amount of blue in the images.
Regarding smartphones, if you use devices with an IOS operating system, you can activate the feature known as "Night Shift" to reduce the blue light emitted by the screen. In the cell phone with Android operating system, depending on the manufacturer, this tool may vary in nomenclature: "blue light filter", "eye comfort". And remember: no keeping the light on at night and touching your cell phone in bed. Your skin and well-being require care! You can use sunscreen with broad spectrum filters and a highly pigmented base for protection.
