Tempered glass is a popular choice for protecting the screen of an iPhone. This type of glass is specially treated to be more durable and resistant to scratches and cracks. It is made by heating the glass to high temperatures and then rapidly cooling it, which increases its strength. This process also makes the glass shatter-proof, so in the event of an accidental drop, the tempered glass will break into small, rounded pieces rather than sharp shards. This not only protects the iPhone's screen from damage but also reduces the risk of injury. Additionally, tempered glass is easy to install and maintains the touch sensitivity and clarity of the original screen. With its excellent protective qualities and user-friendly features, tempered glass is a must-have accessory for every iPhone owner.
