We'd never ask you to give up your beloved morning iced coffee. But if you're reaching for your third cold brew of the day and wondering why your eyes feel dry, scratchy, or tired, your caffeine habit could be playing a role.
Here's what may be happening and what you can do about it:
☕ Caffeine Can Contribute to Dehydration
While moderate caffeine intake is generally fine, too much can have a mild diuretic effect, making it easier to become dehydrated. When your body is low on hydration, your eyes may produce fewer quality tears.
🌬️ Air Conditioning Doesn't Help
Pairing iced coffee with hours spent in air-conditioned offices, vehicles, or homes can create the perfect environment for tears to evaporate more quickly, leaving your eyes feeling irritated.
💧 Balance Coffee with Water
Good news: you don't have to give up your favourite drink. Simply make hydration a priority throughout the day by drinking water regularly alongside your coffee.
💦 Choose the Right Eye Drops
If dry, gritty eyes persist, preservative-free artificial tears can provide longer-lasting comfort and help support a healthier tear film.
If dry eye symptoms are becoming part of your daily routine, it may be time for a dry eye evaluation. Schedule a consultation and find relief that lasts.
