Addressing the Peeling and Flaking of Coatings on Plastic Prescription Lenses

Prescription lenses, particularly those made of plastic, are coated with various treatments to enhance their functionality and protect the wearer. However, over time, these coatings may peel or flake off, leading to a variety of issues. Understanding the causes of this coating deterioration and the steps you can take to address it will help you maintain your vision and comfort.

Causes of Coating Peeling and Flaking

The peeling and flaking of the coating on plastic prescription lenses can be attributed to several factors:

Quality of Coating

Lower-quality coatings may not adhere to the lens surface properly, leading to premature peeling. When the coating isn't securely bonded to the lens surface, it's more likely to flake off over time. Many manufacturers offer high-quality coatings as part of their premium lens offerings, but it's important to understand the quality level you're getting.

Improper Application

If the coating was not applied correctly during manufacturing, it may not bond well with the lenses. This poor application can lead to peeling and flaking over time. Ensuring that the lenses are manufactured by reputable and experienced companies can help mitigate this issue.

Exposure to Chemicals

Cleaning solutions or chemicals, such as those containing ammonia or alcohol, can damage the lens coating. These harsh chemicals can chemically react with the coating, causing it to peel off. It's important to use lens-safe cleaning solutions and to avoid exposing your lenses to harsh chemicals.

Physical Damage

Scratches or impacts can compromise the integrity of the coating, making it more susceptible to peeling. Whether from accidental bumps or long-term wear and tear, physical damage can significantly affect the lifespan of your lens coatings. Take care when storing and handling your glasses to prevent physical damage.

Environmental Factors

Extreme temperatures, humidity, and exposure to UV light can also affect the durability of the coating. Prolonged exposure to these environmental factors can weaken the coating, leading to peeling and flaking. Keeping your glasses protected in a case and avoiding extreme weather conditions can help maintain the integrity of the coatings.

Age of Lenses

Even high-quality coatings can degrade over time due to regular wear and tear. The natural aging process can cause coatings to flake off, even if the lenses were initially manufactured to the highest standards. Regularly inspecting your lenses for signs of peeling or flaking can help you catch the issue early and take appropriate action.

What Should You Do?

If you notice that your lenses are peeling or flaking, the first step is to take them back to the original dispenser. Most anti-reflection coatings, especially those excluding older technologies, are covered by warranties and should be replaced if they fail within the warranty period. Warranties typically range from 1 to 2 years. Here are the steps you can follow:

Steps to Follow

Inspect the Lenses: Carefully examine your lenses for any signs of peeling, flaking, or other damage. Take note of the extent of the damage and the lens that is affected. Contact Your Optician: Reach out to your optician or the manufacturer to inquire about the warranty status of the affected lenses. If they are under warranty, they should be replaced or repaired. Chemical Exposure: If you suspect that the coatings have been damaged by chemicals, clean them with a lens-safe solution and avoid harsh cleaning agents in the future. Avoid Further Damage: Store your glasses in a protective case and avoid exposing them to harsh environmental conditions.

In conclusion, understanding the causes and addressing issues with your prescription lenses' coatings can help you maintain optimal vision and comfort. If you're experiencing peeling or flaking, don't hesitate to contact your optician for assistance.
