Use of a screen protector is largely personal choice - but there are considerations.
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.
Moving from the physical needs and attributes, do you specifically need a “blue light” screen protector? Well, some would say that the “blue light” argument is largely a marketing ploy. Some argue that “blue light” affects sleep patterns, but controls are built-in to the iPad should you wish to manually shift the colour balance away from blue.
Modern iPads automatically adjust the screen colour balance to optimally match ambient lighting. This advanced technology is designed to provide optimal colour accuracy for the display panel. Placing a filter over the display will largely defeat the colour accuracy of the screen - which, for photography or graphics, may be an issue for some users.
In conclusion, do you need a “blue light” screen protector, or just a good quality screen protector? Armed with this information and insight, perhaps you can make an informed choice.
