the texture your eyes feel before your fingers ever touch it
means Having a visible or palpable rough, speckled texture — or, of an image, looking coarse and dotted rather than smooth and sharp.
from From "grain," which came through Old French "grain" from Latin "granum," meaning a seed or kernel — the same root behind "granule" and "granary." The mental picture is literal: tiny seed-like particles you can see and feel. The "-y" suffix is the ordinary English habit of turning a noun into "full of, covered with," the same move that makes "dirty" from dirt and "salty" from salt. The photographic sense — that speckled look of fast film or low light — is a 20th-century extension, named for those visible little specks of silver that behave just like scattered grains.
