What causes eyeglass lenses to crack?

Eyeglasses play a crucial role in the daily lives of many individuals, providing clear visual assistance. However, cracked spectacle lenses can sometimes pose problems, affecting vision quality and even leading to further lens breakage. In this article, we will explore the common causes of cracked spectacle lenses and provide practical advice on proper eyeglass care.

What causes cracked lenses?

Cracks in the film layer of lenses typically stem from three main factors:

1.Prolonged lens usage: Lenses generally need to be replaced every 2-3 years. After this period, some lenses may develop cracks in the film layer due to normal aging. The quality and durability of the film layer can vary across different brands.

2.Incorrect cleaning methods: Using harsh household cleaners or alcohol when cleaning glasses can damage lens coatings and materials, potentially leading to cracks.

3.Rapid temperature changes: Exposure to extreme temperatures, whether hot or cold, causes differential expansion (heat) or contraction (cold) rates between the lens materials and film, resulting in cracks in the lens coating.

How can I prevent lens breakage?

Proper eyewear care, storage, and cleaning are essential to prevent cracks and other damages. It is crucial to avoid exposing your lenses to extreme temperatures, particularly high temperatures, as they are the main catalyst for cracking.

We recommend following these guidelines:

  • Store your glasses in a hard case when not in use to protect the lenses.
  • Avoid leaving your glasses in the car or near sources of high heat for extended periods, as the elevated temperature environment can lead to cracks in the lens's film layer.
  • Use a non-abrasive, lotion-free soap specifically designed for cleaning glasses.
  • Regularly replace your glasses to prevent lens oxidation and aging, which can impact your vision health.

Proper cleaning can extend the life of your lenses
