Dr Shinobu Ishihara from Japan introduced the most popularly known color blindness test in 1917. The test is a color perception test for red-green color deficiencies. It consists of a set of colored dotted plates (PseudoIsochromatic Plate or PIP), each of which shows certain numbers or patterns such as random lines.
Dry eyes are caused to lack of enough good quality tears or due to evaporation of the tears form the surface of the eyes too quickly. This causes a deficiency of lubrication affecting the health of eyes. Common causes of dry eyes are ageing, side effects of certain medications, certain medical conditions, and hormonal changes.
If you are facing problems due to glaucoma, the most important thing to note is that you are not alone. You should not limit your life because of this disease.
