Please check out the Tobii Ocumen landing page @ https://vr.tobii.com/sdk/solutions/tobii-ocumen/
This is a professional paid product, but in the meantime, you can download the free Tobii XR SDK which includes a few samples to demonstrate
what we can do @ https://vr.tobii.com/sdk/develop/unity/getting-started/vive-pro-eye/
Do let us know if we can provide any further information. Best Wishes.
