Abstract
The utility model discloses a lens. The lens is in a curved surface shape, the transverse curvature of the lens is larger than the lengthways curvature of the lens, and namely the lens is flattened lengthways. Therefore, when a lens set is assembled into a pair of spectacles, the lens clings to the pupil of eyes, declination between the focal distance of the lens and the focal distance of an eyeball is reduced, the lens is comfortable and beautiful to wear, and the optical performance of the lens is raised.
Description
Technical field
The utility model relates to a kind of eyeglass.
Background technology
Usually, the structure of eyeglass is the some of spherical crown shown in Fig. 1-4, and its horizontal curvature is with curvature is the same longitudinally.After glasses were made in this lens set assembling, eyeglass and eyeball pupil were not docile, and the focal length offset distance of the focal length of eyeglass and eyeball is big, and optical property is relatively poor, gave the uncomfortable sensation of people when wearing, and were easy to generate visual fatigue, and it is also poor to wear effect, attractive in appearance inadequately.
The utility model content
The purpose of this utility model is to be to provide a kind of eyeglass, to eliminate the focal length deviation of eyeglass and eyeball as far as possible, improves its optical property, make wear more comfortable, attractive in appearance.
In order to reach to above-mentioned purpose, solution of the present utility model is:
A kind of eyeglass is the curved surface shape, and its horizontal curvature is greater than curvature longitudinally.
Wherein, the horizontal curvature of above-mentioned eyeglass is 10C, and vertically curvature is 4.5C.
The horizontal curvature of above-mentioned eyeglass is 6.5C, and vertically curvature is 4C.
After adopting said structure, the utility model is owing to the horizontal curvature with eyeglass designs greater than vertical curvature, being about to eyeglass vertically evens up, like this, after glasses were made in the lens set assembling, eyeglass and eyeball pupil were more docile, and the deviation between the focal length of eyeglass and the focal length of eyeball is dwindled greatly, wear more comfortablely, attractive in appearance, optical property improves.

Embodiment
Shown in Fig. 5,9, a kind of eyeglass that the utility model discloses is the curved surface shape, and the curvature of its horizontal A-A is about to the vertical B-B of eyeglass and evens up greater than the curvature of vertical B-B.
Wherein, shown in Fig. 5-8 preferred embodiment one of the present utility model, the horizontal A-A curvature of eyeglass is 10C among this embodiment, and vertically the B-B curvature is 4.5C.
Be preferred embodiment two of the present utility model shown in Fig. 9-12, the horizontal A-A curvature of eyeglass is 6.5C among this embodiment, and vertically the B-B curvature is 4C.
Emphasis of the present utility model is: the design of the curvature of horizontal A-A is greater than the vertical curvature of B-B, vertical B-B of eyeglass is suitably evened up, still, it is fixed that the curvature of specific design need be come according to the specification of eyeglass, to guarantee the optical property of eyeglass.
There is the accompanying drawing of eyeglass to compare as seen with habit in each accompanying drawing of two embodiment, the utility model is evened up the vertical B-B of eyeglass, like this, after glasses are made in the lens set assembling, eyeglass and eyeball pupil are more docile, deviation between the focal length of eyeglass and the focal length of eyeball is dwindled greatly, wears more comfortablely, attractive in appearance, and optical property improves.
