Proverbs 15:30ESV·traditional attribution

The light of the eyes rejoices the heart, and good news refreshes the bones.

Matthew Henry Presbyterian @wholebiblehenry

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 @doctorgill

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 @jfbcommentary

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.
