How to Utilize your third eye?

Hi - I believe I opened my third eye on accident a few years ago. I was not trying to or even curious about the topic strangely enough.

It seems hard to find good info on the topic. Also, most knowledge seems to be dubious at best and most content is around how to open your eye. Not around what to do/what you can do when it is open. If I did indeed open it how can I use it? Are there any drawbacks? Any all information is much appreciated! Blessings and love to all. : ) Thank you
