An ophthalmic composition comprising geranylgeranylacetone and a fat-soluble antioxidant has an advantage that adsorption of geranylgeranylacetone to a wall of a container is remarkably reduced and thereby the loss of the geranylgeranylacetone content or decrease in the geranylgeranylacetone concentration in the composition is remarkably reduced. Adsorption of the fat-soluble antioxidant to a wall of a container is also reduced due to combination with geranylgeranylacetone.
