クトレンズホルダーに関する。[Detailed Description of the Invention] (Technical Field of the Invention) The present invention relates to a contact lens holder for supporting a contact lens, and particularly to a contact lens holder that facilitates center positioning of a soft contact lens.

すと形くずれの大きな原因となつていた。(Background of the invention) Conventionally, such a contact lens holder is used to measure contact lenses with a lens meter, but although it is possible to measure hard contact lenses, when measuring soft contact lenses, the measurement luminous flux of the lens meter When aligning the center of the lens so that it is concentric with the optical axis of the lens or on a concentric circle, it sticks to the holder and is a major cause of deformation if forced to move it.

and a convex surface 5a of the contact lens 5.
This contact lens holder has a support surface 4 for supporting the contact lens holder facing down, and is characterized in that the support surface is provided with minute irregularities. In a preferred embodiment, the minute irregularities have a textured pattern.

ている。(Example) FIG. 1 is a cross-sectional view of the contact lens holder 1 attached to the lens meter measurement unit 2, and the contact lens 5 is placed on the support surface 4 of the contact lens holder 1 with the convex surface 5a facing down. There is. At this time, four measurement light beams are emitted from the lens meter and pass through four holes 3 in the holder 1.
Contact lens 5
The refractive power is determined (see Japanese Patent Application Laid-open No. 1983-737 for this type of lens meter). The support surface 4 is hollowed out into a spherical shape so as to almost follow the convex surface 5a of the contact lens 5, and is particularly suitable for holding soft contact lenses, since it does not lose its shape and does not stick easily, making it very easy to center the lens. To make it easier, minute irregularities such as a grain pattern are formed.
このような構造であるから、ソフトコンタクト

り凹凸になせば良い。 Because of this structure, even if the soft contact lens 5 is placed on the support surface 4 of the holder 1, the lens 5 and the support surface 4 do not come into close contact with each other, so that the lens 5 is not in close contact with the support surface 4. Movement is smooth and centering is very easy.
Incidentally, in the above embodiment, a grained pattern is preferably formed on the support surface 4, but it goes without saying that the unevenness may be formed in other shapes or by other forming methods. In addition, the hole 3 for the measurement light flux may be one that uses the central light flux depending on the lens meter that is applied.
One hole may be formed in the center of the holder 1. Further, when the holder 1 is manufactured by injection molding of plastic, the grain pattern can be created by making the surface of the mold uneven by corrosion.

れが生じない効果がある。(Effects of the invention) As described above, according to the invention, since contact lenses (especially soft ones) have a structure that is extremely difficult to stick to, it is not only easy to locate the center of the contact lens, but also easy to locate the center of the contact lens. When moving the contact lens using tweezers, for example, the contact lens is less likely to stick to the holder, thereby preventing the contact lens from deforming.
