If you look at the light and see a plus shape, you are not alone! But why don’t we see it as normal?

Let’s describe our eye structure in detail.
The main reason why these light patterns appear when we squint has to do with our eye structure. Located at the front of the eye cornea and lens, one of the main structures that focuses light.
When we squint, our eyelids cover part of our pupils, allowing light to pass through a narrow opening. In this case, our eyelids act as a kind of barrier by restricting the direction of light propagation. diffraction It creates.
Diffraction is when light passes through an obstacle. bend and spread in different directions can be explained as. The bending of light causes crosshair or star-like shapes to be perceived by the light-detecting cells in our eyes (retinal cells).
In addition, light passing through the lens of our eye is caused by diffraction. spreads in certain directions and thus forms a plus-shaped pattern.
Another important factor is small defects in the lens of the eye.
Although the eye lens functions as a perfect optical element, it does not have a perfect surface. So when light passes through the lens bend slightly rotates to different angles.
These small defects and irregularities in our eyes also affect light. on the retina It prevents the light from focusing properly, creating a distribution in the form of bright lines around the light.
