Polycarbonate lenses are a popular choice for eyewear because they are lightweight, impact-resistant, and offer built-in UV protection. Made from a durable type of plastic, these lenses are about 10 times more resistant to breaking than regular plastic or glass lenses, making them ideal for children’s eyewear, sports glasses, and safety goggles.  

Their shatter-resistant properties are especially beneficial for people who lead active lifestyles or work in environments where eye protection is crucial. Despite their strength, polycarbonate lenses still require proper care to maintain their quality and clarity over time. 

Here are some best practices for polycarbonate lens care, including cleaning and storage tips to help you maintain polycarbonate lenses and keep them in top condition. 

1. Use the Right Cleaning Solutions 

Proper cleaning helps maintain the protective coatings and ensures the longevity of polycarbonate lenses. Avoid household products like window cleaners that contain harsh chemicals. These chemicals can damage the lenses’ built-in ultraviolet (UV) and scratch-resistant properties, according to the American Academy of Ophthalmology 

Instead, use a cleaner designed specifically for eyeglass lenses. In a pinch, you can use a mild soap and water solution. Be sure to choose a basic soap without moisturizers.

2. Clean With a Microfiber Cloth 

Although polycarbonate lenses are tough, they can still scratch if frequently wiped with paper towels or even soft fabrics, like your t-shirt hem and towels. Instead, stock up on microfiber cloths designed for eyeglass lenses. Microfiber traps dust and dirt without scratching the lens surface.  

3. Clean Lenses Regularly and Properly 

Now that you know how to properly clean your polycarbonate lenses. The next tip is to keep them clean. Daily cleaning helps remove dirt, oil, and other residues that can obstruct vision and damage coatings.  

Follow these steps: 

• Rinse the lenses with water to remove any loose particles.  
• Gently clean them with a suitable eyeglass lens cleaner or mild soap.  
• Dry with a microfiber cloth to prevent scratching.  
• Repeat as necessary if the lenses become dirty. 

4. Store Glasses in a Hard Case 

When you’re not wearing your polycarbonate lenses, storing them in a hard case helps prevent scratches, dust buildup, and accidental drops. The Cleveland Clinic emphasizes that protective storage is one of the best ways to avoid common damage to any  pair of eyeglasses. Keeping the lenses in a case when not in use shields them from everyday hazards, such as keys and curious pets. 

5. Avoid Extreme Temperatures 

Polycarbonate lenses can become damaged if exposed to extreme heat or cold. High temperatures may cause the lens material to warp, while very cold conditions can make the lenses brittle. The University of Rochester Medical Center advises keeping eyewear in a stable environment to prevent temperature-related damage. This is especially important if you’re in the habit of leaving your sunglasses or a spare pair of glasses in your car.  And if you work outdoors, consider special safety lenses that are made to withstand varying temperatures and a higher level of wear and tear.  

6. Consider Adding an Anti-Scratch Coating 

Although polycarbonate lenses already offer some scratch resistance, an additional anti-scratch coating can further protect the surface. According to the American Academy of Ophthalmology, these coatings can extend the lifespan of the lenses, especially for those who use their glasses frequently or in outdoor environments where scratches are more likely.

7. Use Both Hands When Handling Glasses 

Handling glasses with both hands prevents the frames from bending or twisting, which can cause misalignment of the lenses. This habit also reduces the risk of dropping the glasses and scratching the lenses. By using both hands, you can better maintain polycarbonate lenses in their original condition.

8. Schedule Regular Eye Exams 

Routine eye exams are important for ensuring your prescription is up to date and that your polycarbonate lenses are still suitable for your vision needs. During these check-ups, your eye doctor can assess the lenses for signs of wear and suggest any necessary repairs or replacements to keep your eyewear in optimal shape. 

By following these tips for polycarbonate lens care, you can keep your lenses clear and scratch-free for a longer period.
