I am 14 years old and recently I have discovered that my pupil is like an upside down teardrop. It starts from the middle of my eye and the pupil extends to the bottom of my eye. My left eye is more pronounced than my right but they are both like that. I do not have any trouble seeing or anything. In fact, my vison is 20-25. The only thing I can really think of is that my eyes are really sensitive to sunlight. Even when the sun is setting I would have to squint becasue of the light. Otherwise, light does not affect me. I looked it up and thought it might be coloboma but like I said before I have no eye problems, I don't even wear glasses. I have checked my immediate family's eyes and there appear normal. I would just like to know if there is anything serious about it. Thank you.
