Scratches on eyeglass lenses can be annoying, impair your vision, and hinder your daily activities. Whether it’s due to carelessness in placing your glasses on a hard surface, leaving them out of their case, or accidentally falling asleep with them on, these scratches can occur despite advances in scratch-resistant lenses. Fortunately, there’s a simple and affordable solution using a common household product to repair your lenses without having to resort to expensive treatments or buy new lenses. Why do glasses get scratched? Scratched lenses are one of the most annoying problems for eyeglass wearers. They affect visual acuity and can be dangerous even in situations where clear vision is essential, such as driving or working. Lens scratches often occur due to simple mistakes, such as leaving glasses out of their case, dropping them, or accidentally rubbing them against a hard surface. Other common causes include falling asleep with your glasses on or rough handling while playing with children or pets. Another common cause is cleaning glasses with the wrong products. For example, many people use toilet paper or tissues to clean their lenses, unaware that the cellulose in these materials can actually make scratches more visible. While scratches may seem minor, they can build up over time and compromise the overall quality of the lenses.
