Damage from the sun is in the main from cumulative exposure so 4 days a year is not much. Sunburn events excepted from that comment.
Anyway, with a hat like that you are in the shade all the time, surely, maybe even in the dark
.
Just as an aside, pterygium is fairly common here and put down to sun exposure (as well as other irritants), again from cumulative exposure. My wife has had them removed from both eyes, a quite painful operation. There is increased risk when boating, surfing etc. due to added intensity from reflection off the sea. I don't know how prevalent it is in Texas but Hispanics seem to be at higher risk than many other races.
Sun induced cataracts are an issue too; my mother who only spent a bit more time than average in the sun and on the sea has had both eyes operated on for cataracts (and skin lesions removed too).
I have often wondered about reading with reflective displays in the bright sun whether the risk is increased as it is by reflection from water. Without double checking I think eink reflects about 45% of incident light, but if the passage of the reflection is through glass, thick glass is a moderate absorber of UV and the black eink media is obviously absorptive. Not something I have to worry about now as no longer use a reflective reader.
