Is the blue light considered as UV light?

Blue light, also referred to as high-energy visible (HEV) light, possesses a wavelength longer than UV light, falling within the approximate range of 450 to 490 nanometers. Alongside UV rays, the sun radiates blue light. Nevertheless, blue light manages to penetrate deeper into the oceanic depths compared to UV light. Similarly to UV light, blue light triggers the production of fluoro in certain marine organisms.
