A-center of equivalence
The specific implementation mode is as follows:
referring to fig. 1 to 5, the upper and lower bifocal integrated mirror includes a left lens 1, a right lens 1 and a bridge 2; the left and right lenses 1 are symmetrically formed at two sides of the bridge 2, and shaft seats 3 for mounting the glasses legs are formed at the outer sides of the left and right lenses 1; the lens 1 has a height of 20mm-50mm and a width of 30mm-60mm, and can be worn in various face shapes. Further, an upper frame 4 for connecting the bridge 2 and the shaft seat 3 can be formed on the upper edges of the left and right lenses 1, or a lower frame can be formed on the lower edges of the lenses at the same time, so that three types of full frames, half frames and frameless lenses can be selected.
The lens 1 is designed into a far-looking upper focal area 11 and a near-looking lower focal area 12, the highest upper edge of the boundary line of the lower focal area 12 is positioned at the lower side of the equivalent center A of the lens, namely the area of the lower focal area is smaller, and the lower focal area has the following structures:
firstly, as shown in fig. 2, the quasi-semi-circle occupies the lower area of the lens 1, and the upper edge of the boundary line is a horizontal line, and is located at a distance of 2-10mm, preferably 5-10mm, from the equivalent center a, because the boundary line occupies a larger width, and the lower position of the boundary line is more suitable. Such a semicircle is herein an equivalent to a lens that is circular.
Secondly, as shown in FIG. 3, the distance between the upper edge of the boundary line and the equivalent center is 2-10mm, and the distance between the center of the circle or the center of the ellipse and the equivalent center A is 10-15 mm; the distance between the upper edge of the boundary line and the equivalent center in the structure is preferably 2-5mm, and the circular or elliptical lower focal region 12 occupies a small area and is more concentrated, so that the whole structure is better.
And thirdly, as shown in fig. 1 and 4, the upper arc is arranged, the upper edge of the boundary line is an arc, and the distance between the highest point and the equivalent center is between 2 and 10mm, preferably between 2 and 5 mm.
Fourthly, as shown in figure 5, the lens is half-moon-shaped, the upper edge of the boundary line is a horizontal line, the lower edge of the boundary line is arc-shaped, the distance between the upper edge of the boundary line and the equivalent center is 2-10mm, and the distance between the lower edge of the boundary line and the lower edge of the lens is 1-3 mm; like the first variant, a distance of between 5 and 10mm is preferred.
Considering that the far-looking eyes are generally parallel to each other, and the near-looking eyes intersect at a text or a specific point, similar to the eye-alignment state, for this reason, the distance between the central planes of the lower focal areas 12 of the left and right lenses is less than or equal to the distance between the central planes of the left and right lenses 1, that is, the lower focal area 12 is slightly shifted toward the middle, as shown in fig. 3. The requirement of near vision is met, the eyes can see through the center of the lower focal zone, and the deformation of vision is reduced to the maximum extent. In addition, the luminosity numbers of the upper focal zone 11 and the lower focal zone 12 can be formed on a convex curved surface or a concave curved surface, and the other surface provides the requirement of astigmatism secondary processing when lenses are assembled in the later period.
The equivalent center a of the lens is the center point of the circular lens. The integrated glasses can be used for making myopia glasses for teenagers, such as upper focal zone 11 with high optical power and lower focal zone 12 with low optical power or being flat, so that myopia patients can not or rarely see the myopia and the asthenopia can be effectively prevented, more specifically, the optical power of the upper focal zone 11 is between 130 and 1000, and the optical power of the lower focal zone 12 is between 0 and 600, and various typical values are combined. The glasses suitable for the middle-aged and the elderly can be formed, the luminosity number of the upper focal zone 11 is flat or low, the luminosity number of the lower focal zone 12 is high, for example, the luminosity number of the upper focal zone 11 is-200 to +100, and the luminosity number of the lower focal zone 12 is +100 to +300, so that the glasses can be suitable for the middle-aged and the elderly with myopia or the elderly with hypermetropia.
