Summary:The invention discloses an optical lens for a virtual reality helmet. The optical lens is of a three-piece-type lens set structure and sequentially comprises a first lens, a second lens and a third lens from the object side to the image side along the optical axis, wherein the first lens and the second lens are used for correcting the on-axis aberration and the off-axis aberration, the third lensis used for correcting distortion and dispersion, and the optical lens and a display screen are sequentially placed in front of human eyes. The lens is made of an injection molding material, the weight of the helmet is decreased, and the cost of the helmet is lowered. The amplification factor of an optical system is 5-7 times, the full field angle is 80 degrees, and the maximum distortion is lessthan 11%. The small amplification factor meets the low-resolution screen, and a user can obtain the good immersion sense by using a common mobile phone. 本发明公开了一种用于虚拟现实头盔的光学镜头，它为三片式透镜组结构，沿光轴由物侧至像侧依次为用于矫正轴上像差和轴外像差的第一片和第二片透镜，用于矫正
