Prolonged exposure can cause your retina damage and henceforth might result in disease resembling those of macular degeneration, and can lead to permanent eye vision loss. Additionally, when you are looking into a computer or any other electronic gadget screen for a longer time, the scattered, unfocused blue light noise can easily contribute to digital eye strain.

Now, is there anything that can reduce the harmful effects if you are an IT professional or other jobs of the same kind. Yes, there is!

#4 PC Sunscreen Filter for Windows PC

PC Sunscreen is my final choice when we come across the best blue light filters in the market. It is a very powerful blue light filter software app for Windows 7 or above, which automatically adjusts the monitor color to the surrounding light. The software gradually increases the blue light content on the screen from morning to noon and afterward reduces the same thus helps you to have a good deep sleep. It allows you to set your own bedtime and wake time and the screen color will be varied automatically. This means that the software will be ideal for those having shift works and unusual sleeping patterns. Moreover, PC Sunscreen sets different color schemes for sundry monitors to recoup for dissimilarities in color replication.

This allows the user to have an area which is not shaded, for color sensitive uses. Within in a click of a button you can turn the screen filter on and off and thus users can enjoy full control of daytime and evening screen colors and the timing of the transition.

Wrapping Up

You people might be thinking about what sort of stuff a blogger like me using to avoid the adverse effects of blue light. Personally, I use CareUEyes tool to customize the color temperature and brightness of my laptop screen to reduce eye strain. Don’t take it as a final verdict as my PC and laptop only have CareUEyes software. Turning down the monitor brightness will help to a great extent, but it is not the only thing that causes eye damage. It is the color temperature which is very tough to deal with and very tedious to adjust. I wish your eye to be safe even without using these filters, but if inevitable go for any of the listed light filters. Stay safe and be healthy because it is not only your eye, the whole family sees through it.
