Abstract

The utility model relates to an eyeglass of glasses, and solves the problems that a person wearing glasses is not comfortable and feels tired. The inside eyeglass surface and the outside eyeglass surface of an eyeglass of single eyeglass glasses have cambered surfaces with different curvature radius and central points. The utility model is characterized in that both sides of the inside eyeglass have cambered surfaces with identical curvature radius; each curvature center point is arranged on a connecting line of an end point and the curvature centre of the outside eyeglass surface, and the end point is designed on the outside eyeglass surface according to the general pupil distance of two eyes. The utility model can be widely applied to glasses.

Description

Lens of single lens glasses

The utility model relates to glasses, refers to a kind of eyeglass of single lens glasses especially.

Existing single lens glasses of desiring to be commonly called as goggles, it can reach the appropriate envelope of closing to wear, use or industrial glasses and generally be used for motion, its eyeglass as shown in Figure 3, its inside and outside

side mirror face

11,12 is different radius-of-curvature and centers 11 ', 12 ' formed cambered surface, the center of eyeglass then is a focal length point 13 of thickness maximum, promptly be the eyeglass of a single focal length, this kind eyeglass is on structure, though the basic safeguard function of tool, but wearing down for a long time, easy eye fatigue, key reason just is that this eyeglass is a focal length, rather than according to two general eye pupil pitch-rows from, general standard provides bi-focal about 65-68mm.So single focus lenses of single lens glasses can't allow eyes keep comfortable wearing glasses for a long time meeting under the optical standard requirement.

The purpose of this utility model is to be engaged in studying intensively with great concentration of glasses optics industry through for many years, repetition test, and the above-mentioned shortcoming that overcomes existing glasses provides a kind of eyeglass through improved single lens glasses.

The purpose of this utility model is achieved in that the eyeglass of single lens glasses, its inside and outside side mirror face is to have different radius-of-curvature and the formed cambered surface of central point, it is characterized in that: these eyeglass both sides, inboard are the cambered surface for being formed by the same curvature radius respectively, and its each center of curvature point is to lay respectively on the minute surface of the outside to comply with general two eye pupil pitch-rows on the line at ordered end points and curvature mirror center, the outside.

Above-mentioned design proposal, eyeglass that in other words should the list lens glasses has bi-focal, and according to two eye pupil pitch-rows from and establish, so can reach the existing comfortable for it purpose of similar glasses when wearing.

Be described further below by drawings and Examples.

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model stereo appearance figure;

Fig. 3 is existing glasses list eyeglass synoptic diagram.

As shown in Figure 1, 2: inboard minute surface 2 of the present utility model is different radius-of-curvature and

central point

21,22,31 formed cambered surfaces with outside minute surface 3, and the cambered surface that should inboard minute surface 2 both sides respectively forms for the same curvature radius, and its each center of curvature point 21,22 is to lay respectively to comply with general two eye pupil pitch-rows on the minute surface 3 of the outside on the line at 4

end points

41,42 of ordering and curvature mirror center, the outside 31, and promptly its center of curvature point 21 is positioned on the line at end points 41 and curvature mirror center, the outside 31; Center of curvature point 22 is positioned on the line at end points 42 and curvature mirror center, the outside 31.See that therefrom this eyeglass is a kind of eyeglass of complying with two eye pupil pitch-rows from the single lens glasses with bi-focal.

Claims

1, the eyeglass of single lens glasses, its inside and outside side mirror face is to have different radius-of-curvature and the formed cambered surface of central point, it is characterized in that: these eyeglass both sides, inboard are the cambered surface for being formed by the same curvature radius respectively, and its each center of curvature point is to lay respectively on the minute surface of the outside to comply with general two eye pupil pitch-rows on the line at ordered end points and curvature mirror center, the outside.
