Have your local health department or a lab test your water for bacteria, and If your Report shows a P next to either E.coli or Coliform Bacteria, that means there is the Presence of Bacteria & NO amount of this Bacteria is acceptable so the water MUST be treated to kill the bacteria to make it potable!
Optometrists also test for glaucoma and other eye diseases, and diagnose conditions caused by systemic diseases, such as diabetes and high blood pressure, referring patients to other health practitioners, as needed.
Your optometrist will tell you at the end of your exam when you should schedule your next visit. In most cases it is best to have annual comprehensive eye examinations. Comprehensive eye exams are more than just a check up to see if you need glasses or contacts. The doctor also checks neurological function, the pressure in your eye, eye muscle coordination, and retinal health evaluation.
