do i need a screen protector for my ipad? - Apple Community

iPad screens are robust, but the anti-reflection treatment and oleophobic coating can be easily damaged by tiny grit/dust particles that are unavoidable in many environments. The oleophobic coating is a chemical sacrificial layer that will wear-out over time.

A Screen Protector provides an additional defensive barrier - protecting both the original screen finish and the oleophobic coating. The downside is, perhaps, an increase in screen reflectivity and a slight reduction in contrast.

Your iPad screen is an expensive component of your iPad; a screen protector is a sacrificial layer that is easy and relatively cheap to replace.

Some contributors here will suggest that a screen protector is unnecessary - whilst others may be more cautious, favouring the additional protection afforded by a screen protector. It’s entirely your choice.
