You can see things from God’s point of view

“The precepts of the LORD are right, rejoicing the heart; The commandment of the LORD is pure, enlightening the eyes.” (Psalm 19:8 NASB)

What you see is what you think about

Our brains are similar to computers in that they both are programmed by what is fed into them. And, what goes into them affects what comes out of them. The Bible warns not to set anything before your eyes that is worthless, because it affects what you think about and what you think about is what you are!

“I will not set before my eyes anything that is worthless. I hate the work of those who fall away; it shall not cling to me.” (Psalm 101:3 ESV)

“For as he thinks within himself, so he is.” (Prov. 23:7 NASB)

An enlightened heart

“I pray that the eyes of your heart may be enlightened, so that you will know what is the hope of His calling, what are the riches of the glory of His inheritance in the saints.” (Eph. 1:18 NASB)

your eyes can light up your whole body  

“The eye is the lamp of the body; so then if your eye is clear, your whole body will be full of light.” (Matt. 6:22 NASB)
