Description

Zoom glasses

The invention relates to a kind of glasses, in particular to a distance value which can be detected by a distance measuring device and an object, thereby adjusting a focal length of the zoom lens.

Modern people are prone to myopia because they have poor posture when watching the screen for a long time or reading books. And as people grow older, the crystal of the eye can't focus on the near object. When this kind of focus is limited, it is presbyopia. At present, multifocal glasses have multiple degrees on the same lens, so that users with farsightedness and myopia do not need to wear more glasses. However, the multifocal glasses need to be adjusted by the user to adjust the angle of wearing the lens. In order to adjust the focal length of the lens to the required focal length, the convenience in use is slightly insufficient.

Embodiments of the zoom lens according to the present invention will be described below with reference to the related drawings. For ease of understanding, the same components in the following embodiments are denoted by the same reference numerals.

Please refer to Figure 1 and Figure 2. The present invention is directed to solving the problem that the conventional multifocal glasses cannot automatically adjust the focus. The zoom glasses of the present invention include a lens frame 10, a zoom lens 20, a distance measuring device 30, and a control device 40. The frame 10 has an accommodating space 11 , and the two mirror legs 12 are respectively pivotally connected to two sides of the frame 10 . The zoom lens 20 can be mounted, for example, in the accommodating space 11 of the lens frame 10 (as shown in FIG. 2), or the zoom lens 20 is adjacent to the fixed focus lens 21, and the fixed focus lens 21 and the zoom lens 20 are mounted together. It is disposed in the accommodating space 11 of the frame 10 (as shown in FIG. 3). The zoom lens 20 described above may be, for example, a liquid lens or a liquid crystal lens.

Continuingly, the distance measuring device 30 of the present invention is disposed on the frame 10 for detecting the distance between the distance measuring device 30 and the object. The ranging device 30 can be, for example, active ranging for actively transmitting the ranging signal. The device or the passive ranging device that sends the ranging signal inactively, wherein the active ranging device can be, for example, a laser ranging device, an ultrasonic ranging device, a microwave ranging device or a optical ranging device, and the passive ranging device can For example, the image distance measuring device is not limited thereto, and any device capable of detecting the distance of the object is suitable for the present invention. The control device 40 is electrically connected to the distance measuring device 30 and the zoom lens 20, respectively, and the control device 40 determines whether the distance value detected by the distance measuring device 30 is greater than a preset value or less than a preset value, and directly transmits the adjustment signal to the control device 40. The zoom lens 20 is configured to adjust the zoom lens 20 to a first focal length or a second focal length, thereby imaging an image of the object onto the retina of the user via the pupil of the user. The first focal length may be a negative value, for example, the second focal length may be a positive value, or the first focal length and the second focal length may both be positive values, or the first focal length and the second focal length may both be negative values.

As described above, the present invention can be selectively provided with a switch 50 on the frame 10, and the switch 50 is electrically connected to the distance measuring device 30 for the user to manually turn on or off the operation of the distance measuring device 30.

Please continue to refer to Figure 1 and Figure 2. For example, the present invention provides an effect for a user with near or far vision to automatically adjust the focus of the glasses. When the user puts on the zoom glasses of the present invention, the switch 50 can be turned on, and the distance measuring device 30 starts to detect. The distance measuring device 30 mainly detects the distance between the distance measuring device 30 and an object. For example, the distance between the distance measuring device and the computer screen. Then, the control device 40 electrically connected to the distance measuring device 30 determines whether the distance value is greater than a preset value or less than a preset value, and the preset value may be, for example, 30 cm, 35 cm, or 40 cm. When the control device 40 determines that the adjustment signal is transmitted to the zoom lens 20, the zoom lens 20 is automatically adjusted to the first focal length (focal length of the glasses) or the second focal length (the focal length of the distance glasses), so that the user does not need to replace another one. The lens or adjusting the lens angle of the glasses to achieve rapid zooming helps to clearly understand the effect of imaging, so the present invention is quite convenient and practical for the user.

In summary, the design of the zoom lens of the present invention makes the invention detect the distance between the distance measuring device and the object without requiring a complicated algorithm, thereby allowing the control device to adjust the zoom lens. It is convenient to achieve the effect of automatic zoom.

The above is intended to be illustrative only and not limiting. Any equivalent modifications or alterations to the spirit and scope of the invention are intended to be included in the scope of the appended claims.
