Comprehensive eye examinations should be a regular part of every person’s healthcare routine. They are an important tool in eye health by detecting and preventing eye diseases and evaluating the overall health of the patient. Some diseases, such as glaucoma, develop gradually without symptoms of pain or vision loss, so patients may not notice that anything is wrong until significant and irreversible damage has been done. Early detection of eye diseases allows for a choice of treatment options and a reduced risk of permanent damage.
