A process for destroying a DNA or R

A process for destroying a DNA or RNA of a microorganism on a substance or surface comprising the steps of: generating photons of at least two single line wavelengths corresponding to a peak absorption wavelength of DNA or RNA, the at least two single line wavelengths being at least two of 207 nm, 222 nm, 254 nm, 280 nm, 282 nm, and 308 nm; and directing the photons to a substance or surface to be disinfected, wherein the substance or surface to be disinfected is an eye tissue, whereby the photons are selected to destroy a plurality of chemical bonds within the DNA or RNA of the microorganisms.
