The invention discloses high-covering property glass lens ink and a preparation method thereof. The high-covering property glass lens ink comprises components A and B, wherein the component A comprises the following ingredients in percentage by weight: 60-75% of epoxy resin solution, 0.1-3% of dispersing agent, 1-38.7% of toner, 0.1-5% of defoaming agent and 0.1-6% of filler; the viscosity of the component A is 10000-20000cps at the room temperature of 20 DEG C; and the component B is a curing agent and accounts for 10-20% of the weight of the component A. The two-component high-covering property glass lens ink formed by mixing the component A(the ink) and the component B (the curing agent) is capable of effectively solving the problems existing when conventional glass lens ink is printed on the toughened glass lenses, good in printing effect, easy in achieving high covering and high resistance value properties, excellent in adhesive force to the glass lenses and good in solvent resistance.
