I just got told that my right eye is fine but i have 20/40 on my left eye, do i need glasses ?

Would help: You do not have to have glasses, but having corrective glasses or contact lenses, will improve your vision. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. Get HPV vaccine.
