Review: Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the interior into tension. Such stresses cause the glass, when broken, to shatter into small granular chunks instead of splintering into jagged shards as ordinary annealed glass does.Therefore, the lens protector is very necessary. Many people do not accept the lens protector, that is, after the protector is attached, the picture taken can not show the original camera's shooting effect, it will appear blurred and distorted.
