No, onions are not dangerous to your eyes, though they can cause irritation.
While cutting onions often results in stinging and burning sensations in the eyes, this is merely an annoyance and not a cause for long-term harm. The irritation is due to a chemical reaction that releases a gas that stimulates the nerves in your eyes.
Why Onions Make Your Eyes Water
When an onion is cut, it releases a chemical called syn-propanethial-S-oxide. This gas reacts with the moisture in your eyes to form sulfuric acid, which causes the stinging and tear production.
What To Do When Your Eyes Are Irritated
Even though onion-induced irritation is temporary, it's still important to address the discomfort. Here are some simple steps you can take:
- Rinse your eyes: Flush your eyes with cool, clean water to wash away the irritant.
- Use eye drops: Artificial tears can help soothe and lubricate your eyes.
- Avoid rubbing: Resist the urge to rub your eyes, as this can worsen the irritation.
Key Takeaway
Despite the discomfort they cause, onions are not dangerous to your eyes. According to research, it's essential to treat irritated, burning eyes quickly to eliminate redness and reduce discomfort but there are no long-term risks.
