If it is true that...

Bright light isn't harmful to the retina if the retina isn't sensitized

Then it must be true that...

Retinal injury is caused by ordinary light when the eyes are sensitized by melatonin, prolactin, and polyunsaturated fats

If it is true that...

The nocturnal/stress hormones, especially prolactin and melatonin, make the retina more sensitive to light and more easily damaged

Then it must be true that...

Retinal injury is caused by ordinary light when the eyes are sensitized by melatonin, prolactin, and polyunsaturated fats

If it is true that...

Serotonin uptake inhibiting antidepressants are suspected to cause retinal light damage and macular degeneration

Then it must be true that...

Retinal injury is caused by ordinary light when the eyes are sensitized by melatonin, prolactin, and polyunsaturated fats

If it is true that...

Melatonin lowers body temperature, causes vasoconstriction in the brain, heart, and other organs, and slows reactions

and

Melatonin reduces behavioral sensitivity but increases the eyes' sensitivity to light, causing them to be injured by light that would otherwise be harmless

Then it must be true that...

Retinal injury is caused by ordinary light when the eyes are sensitized by melatonin, prolactin, and polyunsaturated fats

If it is true that...

Melatonin, tryptophan, fish oils, St. John's wort, and omega -3 oils increase the risk of retinal light damage and macular degeneration

Then it must be true that...

Retinal injury is caused by ordinary light when the eyes are sensitized by melatonin, prolactin, and polyunsaturated fats

If it is true that...

Retinal injury is caused by ordinary light when the eyes are sensitized by melatonin, prolactin, and polyunsaturated fats

and

Melatonin and prolactin are induced by stress

and

Darkness is a stress because it impairs mitochondrial energy production

and

Polyunsaturated fats that accumulate in the brain and retina damage mitochondria

Then it must be true that...

Retinopathy of prematurity has blinded tens of thousands of people
