SVIEW 2way Privacy Screen Protector for iPad 10, iPad Air Gen 4–5 & M2, iPad Pro Gen 1–6 & M4, iPad mini 6 (2018–2024)

Privacy for an iPad used on transit or in an open-plan office: micro-louvers narrow the view to about 30 degrees either side of centre, so the screen reads as black to the person beside you. Sview also rates it at 99 per cent UV and around 30 per cent blue-light reduction.

If the complaint is glare or eye strain alone, a filter without louvers is the better buy, since the louvers dim the panel permanently.
