[0009] A peripheral refractive correction area is located at the periphery of the vision protection area.

[0010] As a further improvement of the present invention, the number of the elliptical circles is 3-20 circles, and the nth circle close to the end point of the nose and the n+1th circle close to the end point of the nose are offset toward the nose along the horizontal line, and the offset distance is 0.8-4mm.

[0011] As a further improvement of the present invention, the elliptical circle is composed of a plurality of clusters, and the clusters include a plurality of two tangent small circles of unequal sizes, and the diameter of the small circle is 0.4-1.2 mm.

[0012] As a further improvement of the present invention, the cluster further comprises a plurality of three tangent small circles of different sizes or one large and two small circles, and the diameter of the small circles is 0.4-1.2 mm.
