Hi, Masturbation does make the nerves weak when we do it in excess. It affects the brain and the spinal chord. it s not necessary to affect your vision as such. if the optic nerve is weak already masturbation will worsen your eye s health. A healthy diet will restore your energy slowly but steadily. You can include nuts, fruits and vegetables. It s good to consume vitamin A containing food like papaya ripened mango that wil benefit your eyes. spinach and other leafy vegetables also help you improve your vision. It s advisable to reduce your mobile or laptop using time. Once you feel restored within few months you may gradually start your sexual activity. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Dinesh Kumar, Dentist
