No - our eyes can't "see" wavelengths that are absorbed by DNA

Explanation:

DNA molecules absorb UV light (the ring systems do) - AUGCT - these nitrogenous bases have delocalized electrons and generally absorb light at about 260nm. The visible range for our eyes is about 350nm to 750nm, and so we can't see light that is shorter wavelength.
