I used to masturbate too much 4 to 8 times a day 4 months ago and i guess that's the main reason of my sunken eyes and nearsightedness rather than using phone now i've quit and i'm worried about my eyes and i've not told my family or friends?

I see no reason to believe your self sex habit has anything to do with your eyes. It can make a person feel isolated if they spend too much time isolated from people. Go see your doc and get your eyes checked. You may have a real health problem unrelated to the habit. All you need to tell your family is you need your eyes checked. The rest is not relevant. The doc won't care either.

Agree with Dr. Ferguson. Masturbation is not responsible for your health issues. 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 vaccine. Wish you good health! Safe sex: https://www.hopkinsmedicine.org/health/wellness-and-prevention/safer-sex-guide
