Solomon
Proverbs 15:30BSB·traditional attribution

The light of the eyes cheers the heart, and good news nourishes the bones.

Matthew Henry Presbyterian

Two things are here pronounced pleasant: - 1. It is pleasant to have a good prospect to see the light of the sun (Ecc 11:7) and by it to see the wonderful works of God, with which this lower world is beautified and enriched. Those that want the mercy know how to value it; how would the light of the eyes rejoice their hearts!

John Gill Reformed Baptist

The light of the eyes rejoiceth the heart,.... Not so much the visive power, the faculty of seeing, a strong and clear eyesight; though this is a great mercy, and from the Lord, and to be prized, and does give joy of heart; but rather the objects seen by the light of the eyes, as Jarchi; as green gardens, flowing rivers, pleasant meadows, rising hills...

Jamieson-Fausset-Brown Reformed

light of the eyes-- (Pro 13:9). What gives light rejoiceth the heart, by relieving from anxiety as to our course; so good report--or, "doctrine" (Isa 28:9; Isa 53:1), maketh . . . fat--or, "gives prosperity" (Pro 3:13-17; Pro 9:11). The last clause is illustrated by the first.
