High definition, high transmittance, comfortable to wear, and Abbe number is also the higher the better, high resolution, this is the basic principle, if you will not choose lenses, try to learn from me, I learn lenses is very simple, optical comprehensive performance first, Zeiss below I will not wear, first of all I wear uncomfortable, wear good lenses, poor can not wear at all, I believe many people feel the same as me. ZEISS and Rodenster are my standard. Kemi, Bright Moon, and Essilor are definitely no problem with daily wear. You can wear single vision, digital or progressive lenses, which are customized according to age, because with age, the ability of the eyes to adjust will decrease, like me who is almost 40 years old, it must be better to use digital, the ability of the eyes to see far and near is declining. When you are over 45 years old, you definitely need progressive lenses, because you have already started to age, this is a functional lens, there is no problem at all.
