Red bumps on the eyelid may be an eyelid infection
or an allergy
to an external agent. Since he has no fever
or seems to be bothered by them they may be observed for a while. Check to see if the skin over the lesions appears red and flaky. You may try a mild antibiotic ointment like Chloramphenicol once at night on the lesions for a few days. It should settle soon.
