I don't "hate" bright light, but I find I'm more comfortable in dim/dark places. I used to wear heavy sunglasses as a teen because I always felt I was "light sensitive." Didn't have a clue as to why. The eye doctor said my eyes were fine.
In the case of people in the autistic spectrum, eye disorders has nothing to do with it (typically). It is something called Sensory Integration Disorder. Look it up yourself on wikipedia because this website won't allow me to link to it.
Sufferers have one or more senses that perceive sensory input abnormally. Either too much or too little. I'm on the sensitive side. Sunlight doesn't actually hurt (after some adjustment) but it's just really uncomfortable.
Here is one analogy to bright light (i.e. the sun): Imagine a belt.
For hyposensitive people (Sensory Integration Disorder - who crave stimulation and feel little of it), the sun might even feel like a loose belt, and they want even more crazy blinking strong lights around them.
For many regular folks, it's like a belt that is on securely without any discomfort. The sun is too strong to look into, but it's fine a lot of the time (sunglasses not necessary for comfort for many).
For hypersensitive sensitive folks (Sensory Integration Disorder. I classify into this group) it is like tightening a belt way too tight, it's not exactly hurting but it's quite uncomfortable, and one wants to immediately remedy the situation, it is that bothersome.
And lastly, there's people who have such bad cases of sensory integration disorder that they experience outright severe pain in their eyes, like a belt on so hard it causes noticable physical pain.
