PROBLEM TO BE SOLVED: To provide a primer coat layer having excellent impact resistance, scratch resistance, adhesion and high refractive index in an optical substrate having a high refractive index, in particular, a plastic lens, and having poor appearance such as non-uniformity and white turbidity. Provided is a primer composition for an optical article that does not occur and can be formed without being influenced by a plastic lens material and has good storage stability. SOLUTION: A primer composition for an optical article has a polycarbonate-derived skeleton, an urethane resin having an elongation of 200% or more and 1000% or less, polyethylene glycol having a molecular weight of 100 to 4000, inorganic oxide fine particles, It comprises water and a water-soluble organic solvent.
