你是璀璨的光刺瞎我眼
[nĭ shì cuĭ càn de guāng cì xiā wŏ yăn]
This suggests that the other person is so outstanding, impressive, or dazzling like radiant light, causing the user almost to 'go blind,' meaning completely overwhelmed by their brilliance. It is often used as hyperbole in admiration or sometimes self-mockery.
