@ankara-- If the itching is due to an infection, allergy eye drops are not going to do much.
Are your eyes also swollen and red? If so, you need to see an eye doctor right away. You might have conjunctivitis and that requires antibiotic eye drops. It can be serious, so don't delay treatment.
If you don't have swelling and redness and just itchy eyelashes, then it might just be an eyelash infection.
We all naturally have mites that live on our skin, including on our eyelashes. But sometimes, due to lack of hygiene or due to oil buildup, the mites can become too many and start causing symptoms like itching.
There is a very simple remedy you can do to treat this. You need to clean your eyes with something hot. It can be hot tea, or just plain hot water. Use either a tea bag or a cotton ball and soak it in the hot tea or water. Apply this to your eyelashes for a few minutes. You can gently wipe your eyelashes back and forth. Do this twice a day for as long as it takes for the itching to disappear.
