I have realized that resveratrol alone may be not enough to achieve the anti-photophobic effect. Thus I can only really recommend the specific product that worked:
Swanson Resveratrol 250 mg (Polygonum cuspidatum root extract)
I suspect a synergy of resveratrol and emodin, but it has yet to be confirmed.
Unfortunately resveratrol no longer provides a particular benefit. I have been taking it daily of varying brands for the past half year. I only take one dose before bedtime, but I haven’t tried a greater dosage as my current strategy involves taking a lot of things in small amounts. However I found something else that could be trialed against photophobia.
I have noticed that taking
aspirin (Aspirin Protect 100 mg per pill) before going to bed can help a lot with photophobia in the morning. The only problem is that it stops working after about two days. I had this experience recently, but about half a year ago the same happened, though I can’t tell the exact number of days it helped then. Clearly I lose my ability to respond to aspirin very fast, even if I take daily two pills, but after some time the effectiveness returns. At the moment I can only say that this is less than half a year and more observation would be needed to determine it more properly. Considering this aspirin may be not used practically, but I believe it could still help us through some critical occasions especially if used sparingly.
Another thing I suspect to decrease photophobia is coffee. Actually the
morning coffee may not alleviate depression, but rather slightly improves photophobia and hence my subconscious addiction. I often noticed in the past, that when in the mornings I simply couldn’t look at the brightness of the monitor the morning coffee would soon provide a slight relief that would be just enough to make me able to. If I tried to withhold coffee this acclimatization would usually take more time.
