A colorless transparent silicone lens produced by thermally curing a silicone resin composition comprising (A) an organopolysiloxane having a resin structure comprising R.sup.1SiO.sub.1.5 unit, R.sup.2.sub.2SiO unit, and R.sup.3.sub.aR.sup.4.sub.bSiO.sub.(4-a-b)/2 unit wherein R.sup.1, R.sup.2, and R.sup.3 are independently methyl group, ethyl group, propyl group, cyclohexyl group, or phenyl group, R.sup.4 is vinyl group or allyl group, a is 0, 1, or 2, b is 1 or 2, and a+b is 2 or 3, and wherein number of repetition of the R.sup.2.sub.2SiO unit is 5 to 300, (B) an organohydrogen polysiloxane having a resin structure comprising R.sup.1SiO.sub.1.5 unit, R.sup.2.sub.2SiO unit, and R.sup.3.sub.cH.sub.dSiO.sub.(4-c-d)/2 unit wherein c is 0, 1, or 2, d is 1 or 2, and c+d is 2 or 3, and wherein number of repetition of the R.sup.2.sub.2SiO unit is 5 to 300, the component, and (C) a platinum group catalyst. A silicone lens having excellent flexibility, transparency, and moldability as well as reduced surface tackiness is provided.
