Does a pinhole test clears out if you have Lazy eye or not ?

I see shade under Yahoo logo from my right eye. and the other one is normal. and if you looking at something far away it has a shade coming down. And if i look through a pinhole its very clear! So my question is if you see clear through a pinhole is it a lazy eye or if the image is blurry seeing through a pinhole. Thank you.Does a pinhole test clears out if you have Lazy eye or not ?
It sounds like astigmatism. Your cornea or lens is irregularly shaped and focuses light into two separate images instead of one. Most of the time it is the cornea which is slightly elliptical instead of round which cause this.





Mixed astigmatism means that you are farsighted in one focusing plane and nearsighted in the other. One of the two images from your astigmatism is falling in front of the retina, the other is falling behind it. Since neither one is in focus, your vision is blurry in that eye. It can be easily corrected with glasses or contacts.Does a pinhole test clears out if you have Lazy eye or not ?
No it doesn't sound like a lazy eye. If you had a lazy eye then your vision would not improve with a pinhole. The fact that it has improved with a pinhole tells me that you have some sort of prescription in that eye. It sounds like it may be astigmatism as you described it as a shadow under a image. this is called ghosting and is classic of astigmatism
