How to stop my glasses from slipping down?

I bought this glasses few days ago and i didn’t pay attention to the detail that without the rubber pads it might just slip down on my face, the lens costs a lot so I can’t afford to replace the glasses now..any idea how to fix this? Any DIY like for ex: attaching a small piece of anti slippage tape on the corners OR Any special press on rubber pads that i can buy online? I feel like there must be a solution I just can’t imagine what it is Helpp
