If you are near-sighted this app could help you see further.
Cardboard Spectacles uses Googles Cardboard technology to render your smartphones camera in front of your eyes.
It can be configured to fit your Cardboard model for best experience.
This application requires a Google Cardboard and a smart phone with a good camera to work well.
We recommend getting a cardboard unit which has a adjustable strap, and a hole for the phones camera - just like this one: http://amzn.to/2bOpeOg
This app might not help people with special eye-conditions, but it should work with most people that have trouble seeing far.
How far you can see depends on the quality of your smart phones camera.
