To block the light out of their eyes, until they get accustomed to it. But, it isn't instinct to close your eyes in bright light. Muscles around the eye pull it closed to protect the inner areas of the eye.
People close one eye in bright sunlight to reduce the amount of light entering their eyes and to improve their vision in the bright conditions. This helps to protect the eye from damage and discomfort caused by excessive light exposure.
The characteristic of life demonstrated in squinting in bright light is response to stimuli. Squinting is a reflex action that helps protect the eyes from excessive light and is triggered by the sensory input of bright light.
A bright light that causes you to shut your eyes is called a glare. A glare is harmful in that light enters your eye, but doesn't help you see.
I am not a doctor nor any kind of researcher. Just someone who sneezes when I walk out into the sun. My idea is that when we are exposed to the bright light, we squint our eyes. When this happens it restricts our sinuses. A natural way of clearing our sinuses is a sneeze.
Your pupils will expand as the light dims at twilight, or if in a darkish room. Becoming sexual excited or looking at pornography will also expand the pupils. Using drugs is another cause of expanding pupils, though some drugs will narrow the pupils.

A bright light from the sun or a bright light bulb refers to intense illumination emitted from these sources. The sun produces light through nuclear fusion reactions in its core, which generates a wide spectrum of electromagnetic radiation, including visible light. Similarly, a bright light bulb emits light when electrical energy excites the filament or gas inside it, producing visible light that can illuminate spaces. Both types of light can be blinding or overwhelming at close range due to their high intensity.

The bright light is typically a sudden, intense source of illumination, such as sunlight, a flash from a camera, or a bright artificial light. When it enters your eyes, it triggers a reflex response in your body to protect your eyes from potential damage. This reflex involves quickly closing your eyelids to reduce exposure to the light. This automatic reaction helps to shield the sensitive retina from overwhelming brightness.
