If it hurts your eyes/makes you squint/makes you blink unusually often/gives you vision spots it's not particularly healthy

You also need to account for IR. The IR won't be visible and you can hurt your eyes staring at the dot even if the visible part isn't uncomfortably bright to look at. Since the KD 50 has no IR filter you need to be extra cautious with it.
