Shade and stereo lenses and glasses with corrective vision

The present invention relates to a sunshade and stereoscopic dual-purpose lens and glasses with corrective vision, and particularly relates to a method for allowing a user to have corrective vision, a stereoscopic television, and an outdoor sunshade when wearing the glasses. .

Press, human images are independent because the images seen by the left and right eyes are different, so the images captured by the left and right eyes are different, so a stereoscopic image can be obtained and the distance of the target can be clearly identified; however, in today's images In the display system, the left and right eye images are generally not separately output, so the image seen by the viewer is a flat image, and there is no stereo effect. If the flat screen or the screen can be rendered stereoscopic, the stereoscopic principle should be applied. That is, the image to be seen by the left eye is transmitted to the left eye, and the image to be seen by the right eye is transmitted to the right eye, and a stereoscopic image is formed after being processed by the brain.

In order to enable viewers to watch brilliant stereoscopic images, such as stereoscopic movies, they are produced by the principle of polarized light imaging. The left and right eye images are captured by two cameras with different shooting angles, and then horizontally polarized and vertically The processing is then projected on the screen; when the viewer wants to watch the stereoscopic movie, it is necessary to wear stereo glasses for viewing. The polarizing plates of the left and right eyes of the stereoscopic glasses have different polarization directions, when the light passes through the two polarizers, due to The polarizer filters out light of different polarization directions and only passes light in the same direction. Therefore, the horizontally polarized left eye image can only pass through the horizontally polarized polarizer, and the vertically polarized right eye image can only pass. Vertically polarized polarizer, thus making the viewer's left The eye receives the left eye image and the right eye receives the right eye image, resulting in a visual stereoscopic effect.

In addition, the manufacturer introduced another type of liquid crystal stereo glasses, which uses the principle that the liquid crystal can change the light transmission state by the electric field, and sequentially displays the images of the left and right eyes on the screen, and sequentially applies voltage to the left and right eyes. The lens allows the left and right eye lenses to be sequentially blocked. Therefore, wearing the liquid crystal stereo glasses allows the left eye to see the left eye image, and the right eye to see the right eye image, when the left eye and the right eye of the stereo glasses The stereoscopic image effect can be achieved when the shadow switching between the eyes is so fast that the human visual system cannot distinguish the changes therein.

However, for consumers with far and nearsightedness, after wearing corrective glasses, when they want to enjoy stereoscopic images, they must wear a pair of stereo glasses outside the corrective glasses to achieve the effect of stereoscopic images, but For the user, not only the extra cost is required to purchase the stereo glasses, but also the use and collection are quite inconvenient, and the stereoscopic effect is not good. In addition, most of the existing corrective vision lenses only have the corrective vision function, and There is no shading effect, so the existing stereo glasses still have room for improvement in overall implementation.

Today, the creators, in view of the lack of existing stereo glasses, with their rich professional knowledge and years of practical experience, and then research and improvement, to provide a vision and vision of the sun and stereo dual-use lenses and glasses, in order to achieve better The purpose of practical value.

The main purpose of the present invention is to provide a sunshade and stereoscopic lens and glasses with corrective vision, especially for a user to wear the lens. In glasses, it also has the effect of correcting vision, enjoying stereoscopic TV and outdoor shading.

The main purpose and effect of the sunshade and stereoscopic dual-purpose lenses and glasses for correcting vision, which are attached to or attached to a left-right and right-corrected vision lens of the glasses, and the left polarizer The polarizing polarizer of the right lens has different polarization directions, making it an integrated lens, and with the frame, it becomes a kind of sunshade and stereoscopic glasses with corrective vision.

As described above, the present invention has a shading and stereoscopic dual-purpose lens and glasses for correcting vision, wherein the polarizing polarizer can filter out light having a polarization direction different from that of the polarizing polarizer, so that the luminosity of the image to be seen is reduced. Sunglasses with sun-shading effect.

As described above, the present invention has a shading and stereoscopic dual-purpose lens and glasses for correcting vision, wherein the lens is a myopic lens, an astigmatic lens, a distance vision lens, a myopic distance vision lens, a myopic astigmatism lens, a hyperopic astigmatic lens or a myopic astigmatic lens. one of them.

As described above, the present invention has a shading and stereoscopic dual-purpose lens and glasses for correcting vision. In a preferred embodiment, the polarizing polarizer is a linear polarizing polarizer, and the left and right lenses are linearly polarized polarizers. The polarization directions of the received image light are perpendicular to each other, so that the light with different polarization direction and polarizing plate can be filtered out, so that the two eyes can respectively receive different images, thereby generating a visual stereo illusion, thereby making the creation have the correction at the same time. Vision and the effect of watching stereo TV.

As mentioned above, this creation has a shading and stereoscopic use for correcting vision. In the second preferred embodiment, the polarizing polarizer is a circularly polarizing polarizer, and the polarization directions of the image polarized light received by the circular polarizing polarizer of the left and right lenses are opposite to each other, that is, one is left-handed, and the other is left-handed. One is right-handed, so that the light with different polarization direction and polarizing plate can be filtered out, so that the two eyes can receive different images separately, resulting in a visual stereo illusion, thereby making the creation have both corrective vision and stereoscopic television. The effect of the circular polarizing polarizer is that a quarter-wave plate is attached or printed with a linear polarizing polarizer.

As described above, in the third preferred embodiment, the polarized polarizer is formed by coating a liquid crystal layer with a two-line polarizing polarizer. The images of the left and right eyes are alternately displayed on the screen, and the lenses are applied to the left and right eyes in a continuous interleaving manner, so that the lenses of the left and right eyes are sequentially blocked, and are alternately masked at a frequency of several tens of times per second. Left and right eye line of sight, as long as the screen is displayed alternately, the left and right eye images are displayed alternately, and the liquid crystal stereo glasses are synchronized with the screen through the synchronization signal. When the left eye image is broadcast, the right lens is blackened (opaque) and broadcasted right. When the left eye lens is blackened (opaque), the stereoscopic display effect can be achieved; thereby making the creation have both corrective vision and the effect of stereoscopic television.

In summary, it can be seen that the advantages of the sunshade and stereoscopic dual-purpose lenses and glasses for corrective vision in the whole implementation are as follows:

1. This creation department integrates corrected vision glasses, stereo glasses and sunglasses to overcome the problem of long-term wear of corrective eyesight glasses in the industry when you want to wear a pair of stereo glasses when you enjoy stereoscopic images. The wearer can get rid of the two glasses at the same time. Heavy and uncomfortable.

2. Since the polarizing polarizer can filter out the light having a polarization direction different from that of the polarizing polarizer, the illuminance of the image to be seen is reduced, so that the outdoor sun has the effect of shielding the sunlight.

In order to make the technical means, creative purpose and achievement of this creation more complete and clear, the following is a detailed description, and please refer to the disclosed drawings and component symbols.
