The invention discloses a lens manufacturing process which comprises the steps of hot processing and cold processing, wherein the hot processing specifically comprises the following steps: ingredientpreparation, mold preparation, glass melting treatment, automatic compressionmolding, annealing treatment and lens blank testing; and the cold processing comprises the steps oflens grinding and polishing, lens cleaning, lens coating and lens testing. The lens manufacturing process provided by the invention is not only simple in process, but also highly intelligent, errors of traditional manual manufacturing can be avoided, the cost of lens production can be reduced, and the production efficiency can be improved. Moreover, a lens manufactured by the lens manufacturing process provided by the invention is not only good in quality, but also capable of alleviating defects of fragility and easy fogging, has effects of preventing blue light and ultraviolet light, and improves the comfort of a lens wearer.
