What is the cornea?
This condition occurs when the eye is too long or the cornea has too much curvature, causing nearsightedness.
What is myopia?
This instrument is used to measure the refraction of the eye to determine the prescription for glasses or contact lenses.
What is a phoropter?
Who is credited with inventing the first pair of wearable glasses in the 13th century?
Who is Salvino D’Armate?
These are non-surgical vision correction devices that sit directly on the cornea.
What are contact lenses?
This part of the eye controls the size of the pupil and the amount of light entering.
What is the iris?
A condition characterized by an eye that has trouble focusing on close objects.
What is hyperopia (farsightedness)?
The device that shines light into the eye to examine the retina and other internal structures.
What is an ophthalmoscope?
The term “optometry” comes from Greek words meaning "sight" and this.
What is “to measure”?
A laser surgery used to correct myopia, hyperopia, and astigmatism by reshaping the cornea.
What is LASIK?
The layer of cells at the back of the eye that is responsible for detecting light.
What is the retina?
A condition where the lens of the eye becomes cloudy, leading to blurred vision.
What is cataracts?
A machine that measures the curvature of the cornea.
What is a keratometer?
This American optometrist helped establish the American Optometric Association in 1898.
Who is Dr. William H. Bates?
These lenses help to manage presbyopia by adding additional magnification power for near vision.
What are bifocals?
This clear, jelly-like substance fills the space between the lens and the retina.
What is the vitreous humor?
This common condition involves the gradual loss of central vision due to damage to the macula.
What is macular degeneration?
This device is used to test the visual field by assessing peripheral vision.
What is a perimeter?
This optometry pioneer developed the theory of visual training, and his book, "Perfect Sight Without Glasses", became famous.
Who is Dr. William H. Bates?
A procedure that reshapes the cornea using a laser to treat astigmatism without a flap.
What is PRK (Photorefractive Keratectomy)?
What is the name of the nerve that transmits visual information from the retina to the brain?
What is the optic nerve?
A condition in which the pressure inside the eye becomes too high, potentially damaging the optic nerve.
What is glaucoma?
A specialized instrument that measures intraocular pressure to test for glaucoma.
What is a tonometer?
The first optometry school, the Pennsylvania College of Optics, opened in this year.
What is 1904?
This type of lens can change focus automatically, helping people with presbyopia see both near and far objects.
What are progressive lenses?
