Well, yes, eyelash extensions can just lead to burning eyes in some cases. Generally speaking, for eye lash extension, it can be harmful for your eyes. In common, when we use eyelash extensions, we have to put them directly into the natural eyelash with a bonding agent. And you should know that the bonding agents and glues are made of chemicals. In that way, they can be irritants and cause discomfort and potential eye damage in severe cases. And in some cases, burning eyes, just like you, will occur. For your situation, I will suggest you take off the eyelash extensions. And then have some cool cucumber under your eyes. In that way, it will relieve your situation. Also, eye drops can be used too.
