Hello doctor,

Today while talking with my friend, the sun rays was going into my eyes so I closed my right eye. Only my left eye was open, and the man with whom I was talking to moved his hand much so I noticed that his hand was coming and going for some moment. And my left eye is not in the middle and shifted to the left a bit. I was standing one meter from him. Is this a sickness?



Welcome to

I have gone through your query and understood your concern. Everyone of us have a blindspot in the eye that is 15 degrees to the outside. It is normal, but if you have a large degree of blindspot, that is not normal. I would advise you to take a confrontation test to differentiate these two. A confrontation test is done by fixing your eyes at some distant point and ask someone to slowly move their fingers from outside to inside in front of each eye in all directions, that is in horizontal and vertical directions and observe if you can see the tip of the finger. At a particular point, the tip of finger appears and note this point in all directions. Compare both eyes and also compare with other person and find if there is any difference. For practical demonstration, you can opt for an online consultation.

Thank you doctor,

I understand that his hands came in my blind spot. I tried to make my two fingers disappear 15 degrees from the middle and at the top.

Well, that is absolutely normal. If you still have doubt you can print out Amsler grid which is available online and check if you can see any black spots on that chart or any disturbed lines anywhere.The Amsler grid should be read with both eyes separately and the chart should be held at reading distance. It rules out pathologies of optic nerve too.

Thank you doctor,

And when you focus on left or right with your eyes, is it possible to see the blind spot? Because I am trying and finding it when I turn my eyes to full left or right.



Welcome back to

If you are asking about, if we can pick up or sense the presence of the blindspot when we look to the right or left the answer is blind spot is always there, but our brains are weird in such a way that we do not notice them. With both eyes open, blindspot of one eye falls on the seeing area of the other eye, so we never see any missing area in our visual field if both eyes are open. Only when one eye is closed and tested only we feel that there is a portion of the visual field missing.It is always there when you turn your eyes left or right 15 degrees outside of where you are seeing.Some people just notice that a part of the field is missing when the eye is closed and tested. I hope this helps.
