My eyes have become familiar with the friend's beauty; it is impossible to remain without a glimpse of you.

This profound couplet speaks to the overwhelming power of beauty. The poet is telling his friend to let his eyes get accustomed to his dazzling appearance, because if he doesn't, he fears that even a single glance will be too intense to bear. It's a beautiful plea, suggesting that the beloved's grace is so immense that it requires gradual exposure, not sudden impact.
