The invention provides visible light absorbing glass which comprises the following elements in mole percent: 0-10% of a manganese element, 0-5% of a chromium element; 0-3% of a nickel element, 0-3% ofa cobalt element, 0-3% of a vanadium element and 0-0.5% of a molybdenum element, wherein the sum of the mole percentages of the manganese, chromium, cobalt and vanadium elements is more than or equalto 5%. The invention also provides a preparation method and application of the visible light absorbing glass. The visible light absorption glass prepared by the method of the invention has higher light absorption effect in the range of 300-700 nm; and the transmittance of the visible light absorbing glass is less than or equal to 0.5% under the thickness of 0.20 mm. At the same time, the visiblelight absorbing glass is easy to melt and form, has no internal defects such as bubbles, caking, stripes and the like, has good devitrification resistance, moisture resistance and composition stability, and meets the preparation process requirements of optical fiber imaging elements in thermal performance.
