Spirochete bacteria that can be found in ticks can be transmitted to humans and spread to parts of the body, causing lyme disease. Eye light sensitivity is one symptom.
To my knowledge, lyme disease does not cause light sensitivity, but there are some vision issues that are signs of lyme disease or being bite by a tick. If you have double, blurry or pained vision these are all symptoms of lyme disease.
I had Lymes, yes it did affect my eyes, and left me with light sensitivity. I had iritis, was like looking though greasy glasses, light refracted into stars. Was not a pleasent things to go through.
