[0002] Defocus lens is a kind of special design spectacle lens, and its design principle is based on the concept of "defocus". Defocus refers to the light not falling on the retina, but in front of or behind it. Defocus lens makes different optical focal points in different areas of the lens, so that the light entering the eye can form a clearer image on the retina, thereby improving vision and reducing the burden of eye accommodation.

[0003] The microlens on the existing lens is mostly arranged on the same curved surface, which makes the microlens arranged regularly, and there is still a gap between the microlenses, so that the field of view of the whole lens is limited, and the light on the retina is better imaged.

[0012] Preferably, a ring-shaped fixing base is mounted along the edge of the first lens, the fixing base is adhered to the edge of the first lens, and a ring-shaped mounting groove is formed along the outer wall of the fixing base.

[0013] The design scheme of the present application has the following advantages in application:

[0014] 1. The novel full-view defocus light scattering soft-focus lens is provided with two layers of micro-lenses arranged in a staggered manner, so that the micro-lenses can fully fill the lens under orthographic projection, ensure that light can fully fall on the micro-lenses for defocusing when passing through the lens, improve the imaging of light on the retina, and better reduce eye fatigue.

[0015] 2. The novel full-view defocus light scattering soft-focus lens is provided with a fixing base arranged at the edge of the lens, so that the lens can be installed in position by the mounting groove on the fixing base when installed, the operation of opening a notch on the lens body is saved, and the probability of lens damage is reduced.
