Glasses lenses or plastic lenses are in different demands. If prefer lenses in lightweigt and less costly, you can choose plastic lenses. While glasses lenses will be a better choice for durable and scratch-resistance.

Scratches can’t be removed from any eyeglass lens and anti-scratch coatings can not be removed either. You should replace the lenses if you discover scratches on them.

The choice depends on your priorities and needs. Plastic lenses are more affordable and have good optical clarity, while polycarbonate lenses are more safe and have a stronger impact resistance.

CR39 plastic lenses can typically block around 10% of UVB rays and 60% of UVA rays without any additional coatings. However, it’s recommended to have an anti-UV coating put to your CR39 lenses for complete UV protection, since this can greatly boost their ability to filter UVA and UVB radiation. These coatings can provide up to 100% UV protection, protecting your eyes from the harmful effects of UV radiation.

In order to clean plastic lenses effectively, rinse them with lukewarm water, then use a mild dish soap or lens cleaning solution. Rub the lenses gently, rinse again to get rid of the cleaning solution, dry with a microfiber cloth, and inspect for smudges. Steer clear of abrasive items, strong chemicals, and your breath when fogging. Your plastic lenses will remain clear and long-lasting with proper maintenance and cleaning.

There is no evidence to suggest that plastic lenses are healthy for your eyes. In fact, since plastic is strong and lightweight, many eyeglass lenses are made of plastic materials. However, it’s crucial to ensure that your glasses are correctly set to your eyes because misfitting spectacles can result in headaches, eye strain, and other problems. Additionally, it’s important to take good care of your eyeglasses and keep them clean because some plastic lens materials may be more prone to scratches or other damage.
