Better is the {g} sight of the eyes than the wandering of the desire: this is also vanity and vexation of spirit.

(g) To be content with that which God has given is better than to follow the desires that can never be satisfied.

Wesley's Notes

6:9 The fight - The comfortable enjoyment of what a man hath. Than - Restless desires of what a man hath not. This - Wandering of the desire.

King James Translators' Notes

than...: Heb. than the walking of the soul

Jamieson-Fausset-Brown Bible Commentary

9. Answer to the question in Ec 6:8. This is the advantage:

Better is the sight of the eyes-the wise man's godly enjoyment of present seen blessings

than the (fool's) wandering-literally, walking (Ps 73:9), of the desire, that is, vague, insatiable desires for what he has not (Ec 6:7; Heb 13:5).

this-restless wandering of desire, and not enjoying contentedly the present (1Ti 6:6, 8).

Matthew Henry's Concise Commentary

6:7-12 A little will serve to sustain us comfortably, and a great deal can do no more. The desires of the soul find nothing in the wealth of the world to give satisfaction. The poor man has comfort as well as the richest, and is under no real disadvantage. We cannot say, Better is the sight of the eyes than the resting of the soul in God; for it is better to live by faith in things to come, than to live by sense, which dwells only upon present things. Our lot is appointed. We have what pleases God, and let that please us. The greatest possessions and honours cannot set us above the common events of human life. Seeing that the things men pursue on earth increase vanities, what is man the better for his worldly devices? Our life upon earth is to be reckoned by days. It is fleeting and uncertain, and with little in it to be fond of, or to be depended on. Let us return to God, trust in his mercy through Jesus Christ, and submit to his will. Then soon shall we glide through this vexatious world, and find ourselves in that happy place, where there is fulness of joy and pleasures for evermore.
