Do contact lenses stop onion tears? This is a question that often plagues contact lens wearers, especially during tearful moments. Onions are notorious for causing tears, and the burning sensation they produce can be quite uncomfortable. In this article, we will explore whether contact lenses can provide any relief from onion tears and discuss alternative methods to cope with this common issue.
Onions contain an enzyme called alliinase, which is released when the onion is cut. This enzyme combines with a compound called alliin to form syn-Propanethial-S-oxide, a volatile sulfur compound that irritates the eyes and triggers the production of tears. The tears help to wash away the irritant, but they can also make it difficult to see and cause further discomfort.
Contact lenses are designed to cover the cornea and provide clear vision. While they can protect the eyes from debris and other irritants, they may not be effective in stopping onion tears. The reason for this is that contact lenses do not prevent the release of the irritant from the onion; they merely cover the eye. Therefore, the tears will continue to flow as the irritant remains in the eye.
However, there are some ways to minimize the impact of onion tears while wearing contact lenses. Here are a few tips:
1. Wear disposable contact lenses: Disposable lenses can be replaced after each use, reducing the risk of irritation and infection. This can help to minimize the discomfort caused by onion tears.
2. Use artificial tears: Artificial tears can help to wash away the irritant and provide temporary relief from the burning sensation. Applying a few drops of artificial tears before cutting onions can also help to reduce the amount of tears produced.
3. Wear safety goggles: Safety goggles can provide a physical barrier between the eyes and the onion, preventing the release of the irritant. This can be particularly helpful for those who are sensitive to onion tears.
4. Cut onions in a well-ventilated area: Allowing fresh air to circulate around the eyes can help to dissipate the irritant and reduce the amount of tears produced.
In conclusion, while contact lenses may not directly stop onion tears, they can be used in conjunction with other methods to minimize discomfort. By following these tips, contact lens wearers can enjoy their favorite dishes without worrying about the dreaded onion tears.
