Thank you for putting up your query. Most common causes for puffiness under the eyes could be lack of sleep, overworking your eyes as in computer work and sometimes hereditary also. Other causes can be systemic diseases like
kidney, BP and heart problems. There are various approaches to such problems. .giving adequate rest to the eyes, applying cold compresses, reducing the hours spent on digital screens and applying tear substitutes for dry tired eyes.
I, as an oculoplasty surgeon, in addition, evaluate such patients, if the puffiness under your eyes is causing a significant cosmetic blemish. The available options are dermal fillers or blepharoplasty procedures.
Hope this helps.
