Eyes
A cell with an eye symbol must "see" exactly the indicated number of cells of the eye's color. A cell sees in a straight line in each of the four orthogonal directions until it reaches the edge of the grid or a cell of the opposite color (which blocks the line of sight). The eye's color is the target color; the border around the eye is the opposite color.
This cell must see 0 black cells so the cells around it must be white.
The cell above the "1" cannot be white or it will see 2 white cells.
This cell must see 5 black cells. It can see a maximum of 2 above it so the cells on its left must be black.
Remember that the line of sight is blocked by the opposite color (the white cell in the top-right corner).
The same principle applies to this cell that must see 4 white cells. It can see 1 above it, 1 bellow it and 2 on its right.
This "2" already sees a white cell above it, if we color the cell on its left white then it will see 3 white cells so the cell on its left must be black and the cell in the top row must be white.
