(Concern) My eyes are too sensitive to light.

Is it because presbyopia is coming?

When I go out into the sunlight, my eyes become so sore that I can't open them, and tears keep flowing. I have to walk with my eyes half-closed, which is very uncomfortable. I usually wear glasses, so wearing sunglasses is a bit more comfortable, but changing them is very inconvenient, and I also have to carry a glasses case, which is also inconvenient.

Are there any remedies or medications that prevent eye dryness or are good for the eyes?

Could anyone with experience please give me some advice?
