Do Blue light filters damage mobile phones?

No, as such it can damage the phone. Yes, there can be bugs or lags when you use the app which is quite a basic issue and is very rare as well. It even allows the battery to drain slower because the colour grading changes and becomes very negligible.

Is the blue light filter app good for the eyes?

Partially yes, because I won’t say there is a screen that won’t damage your eyes when it is being used frequently. However, the filter blocks the blue light emission which can be helpful for our eyes. 

What colour is a blue light filter?

It is the amalgamation of yellow, orange and red which is done using high grading colour overlays, that entirely blocks the blue colour which is further called the blue light filter.
