Dr. Reynolds watched the teenager sit in the chair. The kid looked weirdly nervous. He was used to young children acting like that, but a teenager? The kind should have gone to an optometrist at least once in his life.
“Something wrong?” He asked.
“N-no, not really.”
“Come on, I know the equipment I use looks nasty, but you should know it’s nothing to be scared of.”
“I…I know that. It’s just…my vision has been kinda, I don’t know, weird, and I don’t know what you’ll think about it. I don’t want to have big glasses or anything.”
“Oh, is that all? Well, if there’s a problem with your vision and you don’t want glasses, we can look into contacts. But first, let’s see if there’s anything wrong to begin with.”
Dr. Reynolds began his examination. And it quickly became clear that the kid had nearly perfect vision. But there was something else. Something he could not quite put his finger on. Had the kid responded to the letter chart a little too fast, or was it just because he was young? Could he see the smallest letters perfectly, or was there something else at play?
He moved the bulky vision testing equipment out of the way and held up a pen. It was another standard test. He had performed it thousands of times. But for this one, he paid extra attention to what was going on.
“Okay, focus on the top and follow it.” He said.
Normally, when doing this, there would be small, quick movements of the eye when doing this. Dr. Reynolds looked for them to determine how well the eyes could focus and shift. For the teen currently in the chair though, these movements were wrong. They were, if anything, too fast. He was focusing on the pen almost before it moved. Like he could see where it was going to be instead of where it was.
Just to make sure he was not seeing things, Dr. Reynolds moved the pen in different directions. Ways he normally would not. The kid could follow them all perfectly. More than perfectly. He sighed and set the writing implement down.
“How about you tell me what’s going on.” He said. The kid squirmed in his seat. “It’s okay, you can tell me. I won’t share it if you don’t want me to.”
“I…I don’t know what’s going on. My vision goes weird sometimes. It’s like I’m seeing two things at once, but only one of them is real. The other is what’s going to happen. At least, I think that’s what it is. Like an afterimage, but forward? I think? I don’t know.”
Dr. Reynolds stood by, silent. That sounded crazy. To be able to see the future, even just by a second or so, was beyond anything anyone could understand. He needed to confirm whether the kid was telling the truth or just very good at guessing.
“I’m going to hold up a few fingers. How about you tell me how many.”
“Three.” The kid said immediately. Right before Dr. Reynolds was indeed going to raise three fingers.
“That’s…quite the thing.”
“I don’t know how it happened. It just kind of started one day. I don’t know how to turn it on or off. It just happens.”
“Well, I’m afraid this is well beyond my expertise. I don’t know who’s expertise it would be under either.” He watched his young patient wring his hands nervously. “But if it helps, you don’t need glasses.”
The teenager did not respond to his, admittedly poor, attempt at a joke. “So, uh, what do I do now?”
“I have no idea. I’m sure someone out there can help you though. I don’t know who, but there’s all kinds of people out there with knowledge on all kinds of strange things. Maybe try and find one that matches your…” He hesitated. Calling it a condition did not seem right. “Talents.”
“I…guess so?”
“Great. Now, let’s go. You can tell your parents you have 20/20 vision. They’ll be thrilled they don’t have to get you glasses.”
Dr. Reynolds showed the boy out of the examination room. He had some time before his next patient, and a lot of things to think about.
