Hello mam/sir,
Allergy takes time to go..more he will rub his eyes more symptoms will aggravate
Please avoid eye rubbing and do cold compresses with ice wrapped in cotton cloth and on closed eyes
Secondly, tear drops are safe to use but we need to figure out what is causing allergy like dust/heat/change in weather
One pic will help us to identify the eye condition and advise proper treatment
Next Steps
U can continue tear drops with cold compresses
If no improvement,please consult paediatric ophthalmologist
Health Tips
