No, not everyone sees starbursts around lights. The phenomenon of seeing starbursts or halos around lights is known as "halos" or "starbursting," and it is typically caused by certain optical conditions in the eye.
Starbursts occur when light entering the eye is diffracted or scattered by imperfections in the eye's lens or other structures. These imperfections can include irregularities in the shape of the lens, abnormalities in the cornea, or other factors affecting the eye's optics.
Some common causes of starbursts around lights include:
Astigmatism: This is a refractive error in which the cornea or lens of the eye has an irregular shape, causing light to focus unevenly on the retina.
Cataracts: A cataract is the clouding of the eye's natural lens, which can cause light to scatter and create starburst patterns.
Keratoconus: This is a condition in which the cornea thins and bulges forward, distorting the way light enters the eye.
Lasik surgery: In some cases, people who have undergone LASIK or other refractive surgeries may experience temporary or permanent visual disturbances, including starbursts around lights.
It's important to note that seeing starbursts around lights can also be a symptom of certain eye conditions or diseases, so if you are experiencing this phenomenon, it is recommended to consult an eye care professional for a proper evaluation.
However, it's worth mentioning that starbursts can also be a visual effect intentionally created in artistic or digital representations, such as photographs or computer-generated images, for aesthetic purposes.
