What are some of the reasons my eyes would be photosensitive?
144874
A major cause of light sensitivity in people is just that they don't have a lot of pigment in their eyes.  If you have fair skin/hair and light irises, this could easily be the cause.  If this is something that you just started experiencing, you should know that there are many diseases/infections that have photosensitivity as a symptom.  If that's the case for you, make an appointment with your eye doctor.

I have had that problem.  I asked my optometrist about it once.  They told me that it is normal.  It's a combination of a couple of factors:\n1.  Your eyes are trying to accomodate for the lack of light by adjusting to the dark.  This causes your pupils to dialate, which causes blood to flow more rapidly through your eyes, which over-stimulates the optic nerves.\n\n2.  Minor visual hallucination:  Your brain is trying to fill the void with images, trying to make sense of the newly-limited input filtering in.

Don't visit an optometrist, go to an ophthalmologist, who is actually a medical doctor.  I was just diagnosed with dry eye two weeks ago, after first being prescribed antibiotics for pinkeye by my GP.  I've had blurriness in my eyes, but that was probably caused by my contacts leaching the moisture from my eyes.  I also have extreme sensitivity to light, and my eyes were chronically red/burning. I have a follow-up appointment Tuesday, during which my doctor will probably plug my tear ducts. In any case, an ophthalmologist will best be able to diagnose you correctly.

i didnt actually know of that being caused by time, my eyes are blue/grey but they tend to be more blue or more grey depending on my state of mind, this most likely has somethin to do with chemical balancing in the body maybe its a similar thing with age??

Your photos are over-exposed. Just like the reason why you shouldn't look at the sun with the naked eye, pointing the sun at any electronic optical equipment won't work properly. You should have used a strong filter to stop the glare.

I suggest you have your thyroid checked! Thyroid problems often cause irregular astigmatism. Many eye doctors (optometrist/opthalmologist) do not know this. Also, ask them about biofeedback exercises, which work well for some individuals. You may also have other autoimmune problems such as Lupus. I suggest you see an endochrinologist ASAP.

Try changing the solution you use.  Try changing your contacts if you have the disposable ones.  If nothing else then go to your optomologist and see if your eyes have changed.

No life form "knew" that there was any need to develop eyes. At some point after life first appeared on Earth, an accidental mutation in some organism caused certain nerve endings to become light sensitive. This new trait increased the survival probability for this species which means it produced more copies of itself than other species without the mutation. Over a very long period of time, this first primitive "eye" mutated even more, gradually evolving into the modern eye.

What you are experiencing, sounds like photo-sensitivity, aka, "sun poisoning,"and heat rash. Those taking certain medications, pregnant, and those with auto-immune disease have a greater susceptibility to photo-sensitivity, however, anyone can be susceptible. Tiny red, itchy bumps, if treated with hydrocortisone, should subside. Also, getting out of the heat, and direct sunlight can reduce the extent of the area affected.

I've heard that blue eyes are more sensitive to sunlight than other colors.  I would also imagine that sunlight can do at least some damage to eyesight, otherwise we wouldn't need UV-protection sun glasses

they are called phosphenes.\nit's caused by mechanical stimulation of the photoreceptors in your retina.

Yes, Sensitivity to light is one of the unofficial symptoms\nof tourette's\n\n• Light Sensitivity - Heightened sensitivity to light (especially flickering light) with irregular dilation and contraction of the pupils and/or with irregular binocular functions.

Vegetables are great for you, but they aren't going to help you with this.  Your eyes are probably getting tired of focusing so hard or they aren't able to focus as much as you need them to.  If this is something that bothers you, you should make an appointment with your eye doctor.  Often glasses or a few simple eye exercises will help a lot.
