Description

double layer lens glasses

technical field

The utility model belongs to the field of vision correction and relates to double-layer lens glasses.

Background technique

As human eyes degenerate with age, the focal length becomes longer, and the image of objects within a distance of 50 cm is blurred. This is the so-called presbyopia, which is a common phenomenon among middle-aged and elderly people over 40 years old. Especially teachers, practitioners in the precision machinery and electronics industry, etc., need to observe subtle objects. In order to correct vision, people use aging glasses. When observing objects over 50 cm, if you still wear presbyopic glasses, you will not be able to see clearly, especially when driving a vehicle, you must change to glasses.

In the prior art, the glasses used to correct presbyopia include: 1. Traditional reading glasses. Traditional reading glasses have only one focal length, which makes it easy for the aging population to read objects or words at close distances. Remove the glasses, which causes a lot of trouble for the use; 2. Double focal length presbyopic glasses, the upper half focal length of the double focal length presbyopic glasses is designed to observe objects above 3 meters, and the lower half is designed to observe close-up scenery characters, Such a design makes it unnecessary for the wearer of the hyperopic glasses to remove the glasses when observing distant/near objects, which provides great convenience for hyperopic people. Due to the different radians of the lens, the upper and lower parts of the lens form two completely different parts in the grinding of the two focal lengths of the far/near focal length. There is an obvious boundary line between the upper and lower parts of the lens. During use, when the wearer's line of sight moves from top to bottom or from bottom to top, the eyeballs will constantly adjust, resulting in fatigue or dizziness; 3. Progressive lenses, progressive lenses are developed on the basis of bifocal lenses Come on, progressive lens is to use grinding technology to gradually transition between the two focal lengths in the transition between the upper and lower focal lengths, which is the so-called progressive lens. It can be said that the progressive lens is a multi-focal length lens. The disadvantage is that it is progressive There are different degrees of interference areas on both sides of the film, which will create a sense of swimming in the peripheral vision.

Above these existing glasses all are to adopt single-layer eyeglass. From the point of view of the use effect, traditional reading glasses are the best when viewing close-up objects. However, when looking at distant objects, the glasses need to be removed. Because the glasses are often taken off, it is easy to cause improper storage of the glasses, especially when the user is too old and has memory loss. It often takes a lot of time for the user to look for the glasses. And bifocal length or progressive multi-focal length, although convenient, but easy to use fatigue or dizziness. Moreover, due to the complex lens grinding process and the high price of bifocal length or progressive multifocal length, many elderly people cannot bear it.

Moreover, the double-layer glasses that appear on the market are generally designed for framed glasses. The outer lenses usually need to be disassembled and put back when needed, which is troublesome to use.

Contents of the invention

In view of the above problems, the technical problem to be solved by this utility model is to provide a kind of double-lens glasses, which mainly rationally designs the frameless glasses, so as to provide a pair of glasses suitable for their eyesight conditions to the elderly.

In order to solve the above technical problems, the technical solution adopted by the utility model is a kind of double-layer lens glasses, including temples and lenses, and its structural feature is that the lenses include inner lenses and outer lenses, and the inner lenses The pile head is fixedly connected to the mirror leg, and the inner lens is connected through the mirror bridge; the outer lens is arranged outside the inner lens, and is installed on the pile head through a foldable member; the inner lens It is a vision correcting lens, and the outer lens is a compensating lens.

Further, the foldable member includes a fixing clip arranged on the outside of the pile head and a connecting piece arranged on the outer lens, the fixing clip is provided with a first through hole, and the connecting piece is provided with a first through hole. Two through holes, the first through hole and the second through hole are fixed by screws. Through the foldable member, the outer lens can be covered outside the inner lens according to the usage conditions, and can also be folded to the side of the temple.

Further, the inner lens is a hyperopia correction lens, the outer lens is a myopia compensation lens, and the equivalent focal lengths of the inner lens and the outer lens are plano or myopic.

Further, protrusions are provided at both ends of the mirror bridge, and the protrusions are in contact with the outer lens. Because the distance between the inner and outer lenses will affect the compensation effect of the outer lenses, it will also affect the use effect of the glasses. Keep a stable distance to ensure the effect of glasses.

Compared with the prior art, the utility model is equipped with a foldable and compensating outer lens on the traditional frameless presbyopic glasses. When the user looks at close-up objects or reads, the outer lens is folded to both sides of the temple, and only the inner lens is used. When the user raises his head and goes out to watch distant objects, the optical compensation outer lens is folded, and the outer lens is used to compensate the inner lens. The equivalent focal length of the double-layer lens is plano or myopia. In this way, the user can always wear the same pair of spectacles without taking off the spectacles or changing the myopia glasses frequently, which reduces the possibility of damage to the spectacles due to improper storage, and also saves the time of looking for the spectacles. It is especially convenient for teachers and practitioners in the precision machinery and electronics industry. When driving a vehicle, wearing the same pair of glasses can also ensure safety.
