Mild stinging or burning after using any eye drop can occur due to sensitivity to the ingredients or preservatives, but persistent burning, redness, irritation, or discomfort should not be ignored. Since eyes are very sensitive organs, any eye product used regularly should ideally be evaluated for safety and suitability.
Next Steps
As you do not have any diagnosed eye condition and are using the drops only for routine care, it would be suggestable not to use them when you are reacting to that product. A homeopathic consultation can help assess your overall eye-related concerns and suggest appropriate supportive measures if there is a concern, but any over the counter medications are generally not suggested.
Health Tips
Avoid using eye drops without a specific need, avoid touching the dropper tip to the eye if using eye drops ever, and maintain good eye hygiene.
