I guess it's about time I get back to "eye" blogposts, eh? Light sensitivity: it's in our top 10 most common complaints for sure, and there is not a lot of "real world" info out there on the net about it. Light sensitivity can be an important clinical diagnostic factor when assessing patients eyes, for instance in a known contact-lens wearer who has pain, blur & redness in one eye...if it's also extra sensitive to bright lights, that implies possible internal inflammation (iritis) and can change our management of that patient. But a lot of cases of "light sensitivity" are patients with light colored blue or green eyes and larger-than-average pupils. So when it's 105 degrees (like it is over most of Texas today...yeehaw!) they come in saying they're "light sensitive". Well...yes. You are. I agree. There is not much we can do about that, either. Wear sunglasses. So if you think you're "light sensitive"...we probably are not going to be able to do much about it if it's BOTH EYES and longstanding. If you've "always had sensitive eyes (both eyes)"...we believe you, but there's nothing we can do about it. We're more interested in your "light sensitivity" if it is in ONE eye and NEW. So many ocular problems can be narrowed way, way down to just a few diagnoses by asking the question "ONE EYE OR BOTH EYES?"
