Optometry is the health care profession concerned with examination, diagnosis, and treatment of the eyes and related structures and with determination and correction of vision problems using lenses and other optical aids.
Ophthalmology is the branch of medicine which deals with the diseases and surgery of the visual pathways, including the eye and brain. The word ophthalmology comes from the Greek roots ophthalmos meaning eye and logos meaning word; ophthalmology literally means "The science of eyes." As a discipline it applies to animal eyes also, since the differences from human practice are surprisingly minor and are related mainly to differences in anatomy or prevalence, not differences in disease processes. By convention the term ophthalmologist is more restricted and implies a medically trained specialist. Since ophthalmologists perform operations on eyes, they are generally categorized as surgeons.Buy weed online
