- Refraction: The process of measuring the focusing power of the eye to determine corrective lens prescriptions.
- Intraocular Pressure (IOP): The pressure within the eye, crucial for maintaining its shape and function. Elevated IOP is a risk factor for glaucoma.
- Ocular Motility: The movement and coordination of the eye muscles, enabling us to focus and track objects.
- Color Vision: Understanding how the eye perceives different colors and diagnosing color vision deficiencies.
Who are influential figures invision?
- Hermann von Helmholtz: A 19th-century German polymath who significantly contributed to the understanding of the eye's optics and color vision.
- Alvar Gullstrand: A Swedish ophthalmologist who won the Nobel Prize in Physiology or Medicine for his research on the refractive properties of the eye.
- Louise Elisabeth Sattler: A German ophthalmologist and the first woman to become a professor of medicine in Europe. She pioneered cataract surgery techniques.
- Harold Ridley: A British ophthalmologist who accidentally discovered the use of biocompatible plastic lenses for intraocular implants after treating WWII soldiers with eye injuries.

- Maintaining eye health: Regular eye exams can detect signs of eye disease and eye conditions like diabetes that can affect vision.
How is vision applied in practice?
Ophthalmologists work in various settings:
- Hospitals and Clinics: Providing consultations, performing diagnostic tests, prescribing medications, and conducting eye surgeries.
- Private Practices: Offering specialized eye care services to patients of all ages.
- Academic Medical Centers: Leading research on eye diseases and developing new treatment options.
