Embodiment Construction

[0010] The present invention will be further described below in conjunction with the drawings:

[0011] A dual-purpose lens for diaphragm control and liquid presbyopia and myopia is composed of a liquid lens connected with diaphragm control. Two parallel transparent elastic films 3 are separated by spacers 2, and the outer sides of the two transparent elastic films 3 are sealed and fastened separately with two glands 1 (at least three sets of bolts and nuts can be set on the two glands 1 to tighten and seal ). A liquid lens cavity 9 is filled with a transparent liquid between the two transparent elastic films 3 to form a liquid lens. The diaphragm chamber 6 and the diaphragm cover 61 are paired to seal and fasten the powerful diaphragm 5, and the diaphragm nut 52 and the adjusting screw 81 adopt a sealed screw connection, so that they can rotate without leakage. The strong diaphragm 5 and the diaphragm chamber 6 constitute a diaphragm liquid chamber 91, and the strong diaphragm...

Abstract

The invention relates to a pair of presbyopic and myopic dual-purpose spectacles with diaphragm regulation liquid. The pair of presbyopic and myopic dual-purpose spectacles comprises two parallel transparent elastic thin films separated by a space ring, wherein the outer sides of the two transparent elastic thin films are respectively sealed and fastened by glands, a space ring water hole and a diaphragm liquid cavity are mutually communicated, and the pair of presbyopic and myopic dual-purpose spectacles is characterized in that a strong diaphragm is arranged between a diaphragm room and a diaphragm cover. Transparent liquid is fully filled in a liquid lens cavity between the two transparent elastic thin films to form a liquid lens. Through forward and backwar rotation of a scale regulating wheel, a screw is regulated to drive a diaphragm nut to drive the strong diaphragm to move back and forth, thus the space size of the diaphragm liquid cavity is changed, the concave and convex degree of the liquid lens cavity is controlled, one pair of spectacles is of two purposes, the concave and convex degree is randomly regulated, and requirements for presbyopic and myopic spectacles are met at the same time. The concave and convex degree of the liquid lens cavity is regulated by utilizing a diaphragm, and the pair of presbyopic and myopic dual-purpose spectacles, disclosed by the invention, has the advantages of novel ideal, convenience in use and simple structure, is suitable for all people with vision obstacles or is applied to ophthalmology correctors, and is also suitable for classroom teaching demonstration so as to enlighten imagination of students.

Description

[0001] Technical neighborhood: [0002] The invention belongs to the field of vision correction appliances, and in particular relates to a dual-purpose lens for diaphragm regulating liquid presbyopia and myopia. Background technique: [0003] Among the currently known optical correction appliances, whether it is a magnifying glass, a microscope, or reading glasses, or myopia glasses, the main components for adjusting the focal length are glass or other solid transparent materials with a single function. Summary of the invention: [0004] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a diaphragm-regulated liquid presbyopic myopia dual-use mirror with simple structure, convenient use and arbitrarily adjustable, similar in appearance to a general hand-held magnifying glass, suitable for people's habitual usage. The technical solution adopted by the present invention is: a dual-purpose lens for diaphragm control and liquid presbyopia,...
