While opening my eyes for putting eye drops why do i get chills running through my mind and around eyes before the drops drops into eyes. do everyone feels the same sometimes while opening eyes for eyedrops? and is there any harm to eyes?

This is within the spectrum of normal reactions and there is no harm from the chills or other ruminations of your mind. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Get HPV, Flu and Covid vaccines. Wish you good health!
