What happens to your eyes when you drink?

What you’re seeing after a drink isn’t just perception. Your eyes are actually responding in real time. Dr. William Wiley breaks it down: • Slower pupil response → more glare, halos, and harder night driving • Slower brain processing → delayed visual reactions • Tear film disruption → fluctuating, blurry vision (especially with contacts) It’s a combination that can quietly impact how you see and how you function. Without you even realizing it. So if your vision feels “off” after a drink, there’s a real physiologic reason behind it.
