An additional layer of oil and water resistant cheap eyeglasses near me film can be deposited on top of the anti reflection film layer, which will not alter the optical properties of the anti reflection film.

The material of the anti fouling film is mainly fluoride, which can cover the porous anti reflection film layer and reduce the contact area between water and oil and the lens, making it difficult for oil and water droplets to adhere to the surface of the lens. Therefore, it is also known as waterproof film. Vacuum coating is commonly used to coat anti fouling films.

Test method: Use a marker pen to draw a horizontal line on the lens. If the ink completely adheres to the lens and appears, it indicates that the anti oil coating of the lens is poor or average.

Excellent cheap eyeglasses near me lenses do not absorb ink, and ink does not appear on the lens. It only falls onto the lens in the form of water droplets, and once wiped, it disappears.

The hydrophobicity of a good lens film layer is also very good. When water falls on the lens, it is distributed in the form of water droplets, just like summer water droplets falling on lotus leaves. With a gentle shake, the water droplets will fall off. Go test your lenses quickly.

The anti radiation film layer is a special coating process based on the principle of electromagnetic interference shielding, which is treated with a special conductive film to give the lens anti electromagnetic radiation function.

Anti radiation material is a metal compound that forms a barrier on the surface of the lens, reflecting and absorbing low-frequency radiation and microwaves, effectively filtering out electromagnetic radiation waves.
