An anti-glare screen protector is a shield that covers the screen of an electronic device to protect it and cut glare so the operator can use it more comfortably. A variety of companies manufacture screen protection products that can handle glare, including bright sunlight and harsh overhead office lighting. These products vary in style, including temporary screen protectors and more permanent shielding that is designed to last for the life of the device. Such products are often available through hardware and electronics stores.
The most common configuration for an anti-glare screen protector is a piece of plastic sheeting with an adhesive backing. The product usually comes with a protective backing on the front to limit scratches and other problems in shipment. To install it, the user cleans the screen and carefully peels the adhesive backing off to allow the screen protector to stick to the device. The adhesive is designed to be nonreactive with the screen and should not cause streaking or other problems. Once the protector is in the right position, it can be pressed against the screen to adhere and squeeze out air bubbles.
If an upper layer of material is present, the user can peel this off once the anti-glare screen protector is firmly in place. The plastic protects the screen from scratches, dust, and other potential hazards to keep it clean. It also provides a convenient surface for wiping in the event dirt splashes into the screen area. Such protectors can extend the life of a screen.
The anti-glare capacity cuts reflections and glare from bright light. This allows operators to use their devices more comfortably, as they do not need to squint or tilt the device to see the screen clearly. Use of an anti-glare screen protector can reduce eye strain, which can be significant for people who work with devices in bright light regularly. In the event the user needs to replace the screen protector, it should easily peel away without leaving residue.
Some companies manufacture products with a custom fit for specific devices like particular models of cell phones. Consumers can also buy a flat sheet and cut it to size. It is important to measure carefully, as a screen protector that does not fit can create a lip. The lip may attract dust and debris and cause it to adhere to the screen. Consumers should also be aware that thinner anti-glare screen protector films tend to be more prone to peeling away from the screen with extended use.
