1. A method for manufacturing of a coated lens, the method comprising at least the steps of:
applying at least one coating precursor material to at least one surface of an uncoated or precoated optical lens substrate; and
applying at least one single electromagnetic pulse to an optical lens substrate having the at least one coating precursor material to dry and to harden and/or to sinter and/or to cure the at least one coating precursor material for converting the at least one coating precursor material into at least one coating,
wherein
within a range for a total process duration needed for drying and hardening and/or sintering and/or curing the at least one coating precursor material selected from the group of ranges consisting of:
from 100 us to 10 min,
from 300 us to 7 min,
from 500 us to 5 min,
from 1 ms to 3 min,
at least one mechanical property and/or at least one optical property and/or at least one functional property of the coated lens is adjusted to meet a given requirement for at least one of the properties or to obtain a specific target value for at least one of the properties,
wherein the given requirement for the at least one of the properties is met or the specific target value for the at least one of the properties is obtained during the total process duration needed for drying and hardening and/or sintering and/or curing the at least one coating precursor material.
