What are the advantages and disadvantages of Haoqian acrylic lenses?

1. Advantages of Acrylic Lenses

1. Lightweight acrylic lens.

2. In the unlikely case, the lens is crushed, not only the fragments are small, but also not too sharp, and eye and face damage can be minimized. This is the main reason why the mall is advertised as a "security lens".

3. Dyeable: Acrylic lenses are easy to dye, and can be properly matched with clothing.

4. Ultraviolet light with a wavelength of 350mm or shorter is completely blocked, and the effect is much better than that of glass lenses.

5. Since the thermal conductivity of acrylic lenses is lower than that of glass, steam and hot water gas are not easy to blur, even if they are blurred, they will quickly lose.

6. Generally speaking, high-heat, small-volume materials tend to cause dents and mottles on the glass, but when it comes to acrylic lenses, it will automatically pop up without leaving any marks on the lens surface.

7. The surface reflection of acrylic lens is lower than that of ordinary glass plate, and there is less glare.

8. Acrylic lenses have no chromatic aberration. This is because the resin double lens lens has an integral structure, so the chromatic aberration in the molten glass double lens is small.

9. The light transmittance of acrylic lenses is as high as 92%, which is more than 2% higher than that of ordinary glass plates.

10. Acrylic lenses are extremely resistant to chemicals and solvents, and almost all household solvents and chemicals will not affect or damage them.

2. Defects

1. Acrylic lens is less scratch resistant than glass lens, but it can improve the appearance hardening, but its function is limited.

2. Thickness is thicker than glass lens: Amy is humane, too thick lens is ugly, deep myopia is more like fear. Although it has improved a lot recently, it is still much thicker than glass lenses.

3. The density of acrylic lens is lower than that of glass lens.

4. Although acrylic acid is a thermosetting material, once the multilayer film is coated, the appearance of the multilayer film will be cracked by high temperature.
