#### Components
Mupdf is a fast, lightweight, high quality PDF/XPS/CBZ/EPUB viewer for android devices, but it was observed that the application has no option of switching to night mode in its feature, which does not solve the problem of eyes seeing bright light at night

#### Proposal
I will suggest the night mode button be included on the application to improve the applications and increase its  users 

#### Mockups / Examples
Below are pictures of how the MuPDF application interface looks like

Now below is how the night mode button feature will look like when added to the application

#### Benefits
Since the night mode button will be incorporated, it will be more user friendly and also helps the users to  reduce the intensity of light being emitted into their eyes thereby reducing eyes defects
