1.56 refractive index conventional coated lens

Applicable range:

Myopia: 0 to -4.00D (low degree)

Hyperopia: 0 to +3.00D (low degree)

Astigmatism: 0 to -2.00D (low degree)

Thickness characteristics:
The lens is thicker and suitable for people with low degrees. For those with high degrees, the edge will be significantly thickened, affecting the appearance.

Abbe number: about 35-42
Higher Abbe number, lower dispersion, better optical performance, and higher visual clarity.
