Which type of professional is primarily responsible for diagnosing eye diseases?

The correct answer is ophthalmologist because this type of professional is a medical doctor who specializes in the diagnosis and treatment of eye diseases and conditions. Ophthalmologists have completed extensive education and training that includes medical school and residency in ophthalmology, allowing them to perform surgeries, prescribe medications, and provide comprehensive care for a wide range of eye issues.

In contrast, optometrists, while also trained in the eye care field, primarily focus on vision correction and routine eye exams. They can diagnose certain eye conditions but do not perform surgeries. Opticians play a crucial role in the dispensing of eyewear; they fit and adjust glasses and contact lenses based on prescriptions but do not diagnose eye diseases. General practitioners are trained to provide primary care but do not have the specialized training required to diagnose and treat specific eye diseases comprehensively.
