Also Know, is pressing on your eyes bad? Excessive eye rubbing can negatively affect your appearance. It can cause tiny blood vessels to break, resulting in bloodshot eyes, dark circles and wrinkles around the eyes.
Beside this, are Phosphenes bad?

What do blind people see?
A person with total blindness won't be able to see anything. But a person with low vision may be able to see not only light, but colors and shapes too. However, they may have trouble reading street signs, recognizing faces, or matching colors to each other. If you have low vision, your vision may be unclear or hazy.
