To protect eye health and minimize vision fatigue, many people prefer dark mode. Dark mode is especially effective in reducing eye strain when reading or working on documents for long periods of time. It’s also a good idea to use dark mode when reading PDF files. Here are some tips.
Enable dark mode in your PDF reader software
Most PDF reader software supports dark mode. For example, Adobe Acrobat Reader can be switched to dark mode by selecting ‘Display Theme’ from the ‘View’ menu. This setting changes the entire interface to a dark color, including menu bars, tool windows, and scroll bars. Since the color of the document itself will not change, additional settings may be required. pdf 다크모드
Using document color inversion 윤과장의 소소한 일상 이야기
To read a PDF document more effectively in dark mode, it is helpful to invert the document’s colors. For example, in Adobe Acrobat, you can set ‘Page background color’ and ‘Text color’ to your preference in ‘Document color options’ through ‘Edit’ > ‘Preferences’ > ‘Accessibility’ menu. In general, it’s a good idea to set the text to a light color and the background to a dark color.
Create an appropriate lighting environment
Ambient lighting is also important when using dark mode. In an environment that is too dark, your eyes may experience excessive fatigue, so it is recommended to use a soft desk lamp to maintain adequate lighting. Direct light may reflect on the screen and increase eye fatigue, so lighting must be adjusted appropriately.
Use blue light filter
Most digital devices emit blue light, which can cause eye strain and disrupt sleep patterns. It is recommended that you use settings to reduce blue light on your computer or mobile device, or use blue light blocking film or glasses. This helps increase eye comfort, especially when reading or working for long periods of time.
Take regular breaks
Regardless of which mode you use, staring at one screen for long periods of time can be very taxing on your eyes. So, it’s a good idea to practice the 20-20-20 rule (work on the computer for 20 minutes, then look at something 20 feet away for 20 seconds).
