Claim 23:
24. The method according to claim 14, the coated lens comprising an uncoated or precoated optical lens substrate and at least one coating, the method comprising the following steps:
a) providing at least one uncoated or precoated optical lens substrate having a front surface and a back surface, the optical lens substrate having a transparency in a wavelength range of from 400 nm to 800 nm,
b) applying at least one coating precursor material to at least one of the surfaces of the uncoated or precoated optical lens substrate, the coating precursor material having a transparency in a wavelength range of from 100 nm to 1100 nm,
c) irradiating the at least one surface of the uncoated or precoated optical lens substrate having the at least one coating precursor material with at least one single electromagnetic pulse for a total process duration resulting in the coated lens, the single electromagnetic pulse having a wavelength range of 100 nm to 1100 nm,
wherein
the total process duration is in a range of from 50 μs to 20 min,
in a wavelength range of from 400 nm to 800 nm, the at least one single electromagnetic pulse passes through the optical lens substrate with minimal or no absorption and through the coating precursor material with minimal or no absorption,
in a wavelength range of from 100 nm to <400 nm and in a wavelength range of from >800 nm to 1100 nm, the single electromagnetic pulse is absorbed by the optical lens substrate with a transmittance of <80% and passes through the coating precursor material.
