Your friend is having eye sight problem. She is not able to see clearly a distant uniform window mesh and it appears to her as nonuniform and distorted. The doctor diagnosed the problem as:

The friend cannot see distant objects clearly, which indicates myopia (short-sightedness). In myopia, distant objects appear blurred because the image is formed in front of the retina.

Additionally, the uniform window mesh appears non-uniform and distorted. This distortion indicates astigmatism, a condition where the cornea or lens has different curvatures in different planes, causing light rays in different planes to focus at different points. This makes straight lines appear wavy or distorted, and a uniform mesh appears non-uniform.

Therefore the diagnosis is myopia with astigmatism.
