Hi @priyanka, whist we not maintain a list of fake eye products, those which we use at Tobii are usually available to purchase to external customer so kindly get in touch directy with Tobii Pro Sales @ https://www.tobiipro.com/contact/sales/ who should be able to put you in touch with your local supplier, depending on your location.
That being said, a cursory glance online reveals a number of similar products available but we cannot vouch officially as to their efficacy in eye tracking.
