I really don't like LED lights. Even compared to fluorescents, which are pretty horrible. They replaced all the fluorescent lights at my work a while back with LED's and for the first month all my coworker's were complaining about sore eyes and headaches, they hurt my eyes, they're hard to look at, they even mess with calibrating the lasers on our machines. It's been more difficult since the bulbs were changed. Sometimes the laser doesn't read the calibration lens properly. This didn't happen before.

Probably shitty LED bulbs with poor drive circuitry. Eye strain is usually caused by flicker, which often comes from bulbs that use PWM (cheap dimmable bulbs) or don’t have large enough capacitors (or any at all and just rely on a diode and resistor to manage voltage, so you end up suffering from 50/60hz flicker, frequently half wave rectified making it even worse).
