That's what prayer and confirmation by the Holy Ghost are for. Perhaps visually impaired obedience at times, but that's what faith is.

Sorry for the long quote but I think it's better than what I can say:

Obedience based on faith is not blind obedience.

We render intelligent, constructive obedience when we voluntarily, humbly, and happily obey the commands of our Lord.⁷To obey! To hearken! What a difficult requirement! Often we hear: “Nobody can tell me what clothes to wear, what I shall eat or drink. No one can outline my Sabbaths, appropriate my earnings, nor in any way limit my personal freedoms! I do as I please! I give no blind obedience!”

Blind obedience! How little they understand! …

When men obey commands of a creator, it is not blind obedience. How different is the cowering of a subject to his totalitarian monarch and the dignified, willing obedience one gives to his God. The dictator is ambitious, selfish, and has ulterior motives. God’s every command is righteous, every directive purposeful, and all for the good of the governed. The first may be blind obedience, but the latter is certainly faith obedience. …

Is it blind obedience when one regards the sign “High Voltage—Keep Away” or is it the obedience of faith in the judgment of experts who know the hazard?
Is it blind obedience when the air traveler fastens his seat belt as that sign flashes or is it confidence in the experience and wisdom of those who know more of hazards and dangers?

Is it blind obedience when the little child gleefully jumps from the table into the strong arms of its smiling father, or is this implicit trust in a loving parent who feels sure of his catch and who loves the child better than life itself? …

Is it then blind obedience when we, with our limited vision, elementary knowledge, selfish desires, ulterior motives, and carnal urges, accept and follow the guidance and obey the commands of our loving Father who … created a world for us, loves us, and has planned a constructive program for us, wholly without ulterior motive, whose greatest joy and glory is to “bring to pass the immortality and eternal life” of all his children? [See Moses 1:39.]⁸

It is not blind obedience, even without total understanding, to follow a Father who has proved himself.⁹
