If there's one thing that sets hydrogel screen protectors apart from their plastic or glass counterparts, it's the inherent self-healing ability they have over time. Clarity: They are extremely transparent, keeping the screen of your device bright and sharp. The flexibility of the material makes it bend against curved screen edges — enabling full coverage. Hydrogel protectors are also designed to be easy to use, with a strong adhesive that prevents bubbles from forming – resulting in a smooth finish free of blisters. Not only that, but they too can be removed with no sticky mess behind, which again makes them a tempting option for screenguards.
