Abstract

These days human race is facing lots of physical and mental problems. Now a day’s diagnosis of problems at their earlier stage is very important for providing complete cure to them. Here we present a fully automated, computerized technique for diagnosing human visual problems. We have utilized ‘LABVIEW’ for its precision and accuracy. Visual diagnosis includes color blindness – inability to perceive differences between some of the colors that others can be distinguished, because of eye, nerve or brain damage are due to exposure to certain chemicals. Other tests include visual acuity –quantitative measure of the ability to identity the black symbols on a white background at a standardized distance as the size of the symbol is varied. It is based on the sharpness of the retinal focus and the sensitivity of interpretative faculty of the brain.

Visual field test- Performed to analyze a patient’s visual field. The test may be performed by a technician using an automated machine. Other names for this test may include permity, tangent screen exam, etc,. This virtual instrument for screening vision problem is ideal for mass screening in education institutions, clinics, etc., for the early detection of color blindness.
