You might be affected by a disorder of the eye, where the nervous cells in the eye are not working properly. This may be due to aging, high blood pressure, or diabetes. Nevertheless, it also might be that a person exhibits signs of blurred, partial, or total vision loss. Treatments for that might include taking special eye drops or doing procedures that will be put in place to protect your nerve endings that are situated in the eye. Your optometrist can prescribe eye drops or other medications to improve your vision.
