A biconvex lens for VR glasses

technical field

The utility model relates to the technical field of virtual reality glasses, in particular to a biconvex lens for VR glasses.

Background technique

Virtual Reality (VR) technology is a computer-generated, interactive and immersive visual virtual environment proposed in the 1980s. It can generate a variety of virtual environments as required and is widely used in urban planning. , driving training, interior design and other fields. In recent years, with the development of computer computing power and various types of sensors, various types of virtual reality helmets have appeared on the market, which are basically composed of a display screen or a mobile phone and a pair of eyepieces, through which the human eye can see the enlarged images on the screen. For images, the sensor senses the changes of the human head and adjusts the images on the left and right screens, so that the human eyes can see three-dimensional and interactive visual images.

At present, the eyepieces used in virtual reality helmets on the market are generally plastic convex lenses. The shorter the focal length, the larger the viewing range, and the more compact the equipment, the better the immersion it brings to the user. The blurring and dispersion of the edge image are aggravated, and the image is seriously deformed, so the focal length cannot be reduced blindly.

In order to solve the problems of distortion and dispersion caused by a single lens, the general processing method is to perform software preprocessing on the undistorted image, and then input it to the left and right screens to compensate for the aberration caused by the lens. However, this method cannot solve the problem of blurred edge images, and will cause a decrease in the frame rate and bring dizziness to the user.
