This governing body is responsible for ensuring health and safety at work
OSHA
This part of the eye contains the most refractive power
Cornea
This instrument is used to view the outer and anterior adnexa of the eye using various degrees of magnification and lighting
Biomicroscope
This refractive error is characterized by a long axial length of the eye causing the focal point to be in front of the retina
Myopia
This is the horizontal measurement of the eyewire
A
This governing body is responsible for ensuring products are made to national standards that ensure durability, function, and performance
ANSI
This gland is responsible for producing the oily layer of the tear film
Meibomian Glands
This instrument is used to examine the interior chamber of the eye including the retina, optic disc, and retinal blood vessels
Ophthalmoscope
This refractive error is characterized by a short axial length of the eye causing the focal point to fall behind the retina
Hyperopia
This is the vertical measurement of the eyewire
B
This governing body is responsible for ensuring medicines and food are safe for the public and are labelled correctly
FDA
This layer of the cornea is responsible for the pumping action that maintains the corneas state of dehydration
Endothelium
This instrument is used to measure the interocular pressure often using a puff of air, but may also be used as a "pen" or a prism
Tonometry
This refractive error is characterized by two points of focus
Astigmatism
This is the measurement that is also known as the Frame PD, or Distance Between Centers
Geometric Center Distance
This governing body was created to protect personal health information and ensure confidentiality in care
HIPAA
This tunic of the eye contains 12 layers of photoreceptive cells
Retina
Determines the refractive error of the eye using a "streak of light" in conjunction with lenses in the phoropter or a set of trial lenses
Retinoscope
This refractive error is characterized by both focal points falling in front of the eye
Compound Myopic Astigmatism
This measurement is used when calculating vertical decentration and is found at 1/2 the B measurement
Datum Line
This documentation informs first responders for first aid treatment and individuals working in a lab setting the risks associated with chemicals they may come in contact with
This part of the retina contains the three type of conical photoreceptor cells that absorb blue, green, and red wavelengths of light
Macula lutea
Instrument used to measure the surface of the cornea and map it
Corneal Topographer
This refractive error is characterized by one focal point falling in front of the eye and another falling behind the eye
This measurement is 2x the longest radii from the geometric center of a frame
