The present invention relates to a hard lens cleaning device using low-vacuum plasma capable of stably modifying the surface of a hard lens to have high hydrophilicity and low surface profile without physically damaging the hard lens and cleaning at the same time. The present invention provides the hard lens cleaning device using low-vacuum plasma characterized by including a body with a predetermined internal space; a cover installed in the body to be opened and closed, forming a space between the body and the cover; a lens receiving unit formed inside the body where the hard lens is seated; a pair of discharge electrodes installed while interposing the lens receiving unit and producing plasma when a current is applied; a low-vacuum controlling means connected to the closed space between the body and cover, and controlling an inflow and an outflow of gas; and a control unit controlling the operation of the discharge electrodes and the low-vacuum controlling means, and producing plasma under a low-vacuum condition when cleaning the hard lens. |
