In general, a computer monitor does not need to be protected from physical damage. As such, a screen protector made solely to protect from damage isn’t always necessary. The only exception to this is laptops. Since you’re carrying a laptop with you, the chance for accidental damage is higher. However, many privacy screen protectors protect both your sensitive information and the physical aspect of your computer monitor. So, when you install a privacy film, you also get a certain level of protection from accidental damage.
