What Problems Occurs Due To Pinhole Pupils

Both the front and back areas are vital for optimum vision. When we concentrate on the front of the eye, the cornea's pupillary opening, and lens play an important part in the quality of our vision. As technology advances lens-related issues like cataracts are usually handled in a way that is optimal. 

However when we consider the cornea, particularly in cases of an extremely irregular corneal astigmatism this may pose a challenge even for the highly experienced surgical surgeons of the anterior and corneal segments. If you have a case of uneven corneal astigmatisms, the doctor could think about shifting the focus away from the cornea towards how big the opening in the pupil is.

With decreasing pinhole pupil size the quality of images improves, and aberrations diminish. With decreasing pupillary size, it should be noted that the exact position of the smaller opening is crucial.

Also, with an open pupil, it is possible to see a decrease in the illuminance of the retina. This could be a problem in dim lighting situations. But, this may be overcome through the ability to adapt. 

In addition, when pupils shrink in size it is possible that the focus grows however, there is rarely a noticeable decrease in stereoacuity as well as a decrease in the circle of diffusion light, which improves the quality of images and thus, better vision,
