Concerning your son's issues......there has been extensive review of the claims concerning Irlen's syndrome and their supposed research supporting it and there is no medical evidence that this "syndrome" exists at all. I would not waste your time testing for this condition in your son. The only thing that the treatment for Irlen's syndrome has been proven to provide beyond a shadow of a doubt is the ability to transfer money from your bank account to that of the person offering the treatment.
I would suggest you have your son evaluated by an ophthalmologist
to rule out any ocular pathology. If this comes back normal then she would be able to recommend other tests to further evaluate your son and offer possible treatment options.
There are many possible causes of your light sensitivity. The most common would be dry eyes
Dry eyes is very common and can be improved by a stepwise series of therapies. First, the use of natural tears 4-6+ times/day to augment your natural tear production, then temporary punctal occlusion of the lower puncta, then temporary occlusion of all 4 puncta then surgical ( non-reversible) closure of the puncta.
Blepharitis is a condition where glands in the eyelids are not functioning normally. They become plugged and instead of putting out their normal clear, oily secretions, they put out thick, toothpaste like gunk.
The best treatment for this condition daily lid scrubs combined with warm compresses. I like to use baby shampoo for lid scrubs. In the shower, place the shampoo on your index fingers, close your eyes, raise your eyebrows (to stretch the skin on you eyelids) and scrub back and forth along your eyelashes for 3 to 5 minutes. The hot water in the shower helps to soften the plugged oils in the glands while the mechanical scrubbing with your soapy fingers removes the oils.
Other, less common but more severe, causes of photophobia
inflammation (uvieits) and some forms of glaucoma
. These can only be diagnosed by an ophthalmologist during a complete eye exam.
