This invention describes a device far attaching a corrective lens (eyeglass type) to the ocular end of a rifle mounted telescopic sight (riflescope). The invention consists of a tube with one end (ocular end) attached to the ocular end of the riflescope, a second tube with one end (ocular end) threading into the open end (eye end) of the first tube, a lock ring threading onto the outside circumference of the second tube (ocular end), and a circular corrective lens (with the optical centre at the centre of the lens) inserted just inside the eye end of the second tube. Moving the corrective lens from the shooter's eyeglass frame to the riflescope allows the shooter to view the target through the optical centre of the corrective lens (thereby obtaining a clear image) even though his head is inclined towards the riflescope. Prism is also eliminated.
