THE ADVANTAGES AND DISADVANTAGE OF FRESNEL LENS IN VR APPLICATIONS

Summary

In order to make the VR headset lens thinner and lighter, some lenses use Fresnel lenses. This lens has the same curvature as a normal lens, but has threads of different sizes on one side. But using a Fresnel lens means you need to make a certain sacrifice. You can make a multi-threaded lens so that you can see clearer images. But the light cannot be focused on one point, and the curvature is always incorrect. In addition, you can also use a Fresnel lens with fewer threads to help focus the beam and improve contrast, but the sharpness of the image will be impaired. The VR head-mounted display device uses the characteristics of the Fresnel lens in short distances...

Disadvantage of Fresnel Lens in VR Applications

In order to make VR head-mounted display lenses thinner and lighter, some of the lenses use Fresnel lenses. Fresnel lens has the same curvature as a normal lens, but has threads of different sizes engraved on one side. But using a Fresnel lens means you need to make a certain sacrifice. You can make a multi-threaded lens so that you can see clearer images. But the light cannot be focused on one point, and the curvature is always incorrect.

In addition, you can also use a Fresnel lens with fewer threads to help focus the beam and improve contrast, but the sharpness of the image will be impaired. The VR head-mounted display device uses the characteristics of the Fresnel lens to achieve effective image display in a short distance, which is also the basic working principle of the lens in the current mainstream VR head-mounted display.
