Almost two years ago I went to Walmart to get a new prescription for my reading glasses. It had been about ten years since I started wearing glasses and I thought I probably needed a stronger prescription.
The doctor had me look into a machine that looked like a VR headset, gave me a clicker, and told me to click the button every time I saw a flashing light inside the machine.
I waited.
After about ten seconds she told me again to click the button when the lights flashed. That's when I realized the test had already begun and I wasn't seeing anything.
I set up an appointment with an ophthalmologist a couple months later. He charged me $160 to do nothing and referred me to a retina specialist who charged me $600 for doing nothing and sent me to the local university for more tests. The team at the university was great - I wish I could have skipped the other two and met them first. When the test results came back I was declared legally blind due to a constricted field of vision. Total blindness is probably a year or two away.
A couple days ago u/Dark_Sunlightx asked a
$1 similar to yours and I'm too damn lazy to retype my answer so there's the link. It's bedtime now but if you have any questions after you read that link I'll happily answer them in the morning.
You're going to be okay, bro. I promise.
