For many it is because we are having trouble seeing. We anticipate a new glasses or contact lens prescription to correct the blurry vision. For some a simple prescription may not be the answer.
Many eye diseases are silent.
We feel no pain or discomfort and the loss of vision is slow. Symptoms are not noticed by patients until significant permanent damage has occurred. Routine comprehensive eye care can easily prevent the loss of vision from many eye diseases. Our eyes are connected with the rest of our body through common vessels and nerves. Many diseases have signs that are detected in the eyes.
