Mixed astigmatism - ANSWER one meridian is nearsighted and the other is farsighted spherical lens - ANSWER power is the same in all directions Spherocylinder lens - ANSWER a lens that has an astigmatism correction and spherical correction for either myopia or hyperopia, with the plane cut across the longest part of the sphere pupillometer - ANSWER A device for measuring the pupillary distance pupillary distance - ANSWER the distance from the center of one pupil to the center if the other pupil principal axis - ANSWER this line goes through the center of a lens, perpendicular to the surface of the lens optical center - ANSWER spot where light passes through a curved lens without bending. you'll find it at the thinnest point of a minus lens and the thickest point of a plus lens. light striking the lens at any other point will bend, due to the curvature of the lens index of refraction - ANSWER amount a material is able to bend light. the higher a materials index of refraction is the more it bends light and the thinner the lens can be CR-39 - ANSWER plastic lenses, lowest index of refraction= 1.498 crown glass - ANSWER index= 1.523 polycarbonate - ANSWER index= 1.586, impact resistant, UV protection, easily scratched, allows for thinner lenses trivex - ANSWER index= 1.53, superior optics than poly, impact resistant, UV protection Photochromic lenses - ANSWER Activated by UV, do not darken behind windshield, UV Protection polarized lenses - ANSWER Reduce glare, UV protection blue blocking lenses - ANSWER help reduce melatonin blocked by digital devices vertex - ANSWER the distance between the front of the eye and the back of the lens in a pair of glasses effective power - ANSWER the percieved change in power of a lens when the finished lens is not worn at the distance that the eyes were examined Compensated power - ANSWER the new power that the new lens will need to have in order to have the same effective power as the original lens when it is places in a new vertex distance phoropter - ANSWER a device used to test eyes that uses a vertex of 12 mm frame front (chassis) - ANSWER another name for the frame front. part of frame that surrounds the lenses bridge - ANSWER the portion of the frame between the lenses that sits over the nose temples - ANSWER parts of the frame that go on the sides of the head to hold the glasses in place over the ears nose pads - ANSWER most metal grames have nose pads which are pads that sit on either side of the nose end pieces - ANSWER very outer ends of the chassis where youll find the hinges that connect the temples to the frame front lens block - ANSWER small plastic disk size of nickel with adhesive tabs on both sides of it. one side of the block is attached to the uncut lens, the other side of the block is attached to the chuck of the edger to hold the lens while the blade of the edger cuts the lens edging - ANSWER using an optician machine, called an edger, to cut the lens to fit in a frame MRP raise or drop - ANSWER Vertically decentering a lens when there is an imbalance between the two eyes Lensometer - ANSWER device used to measure the prescription of a lens- sphere, cylinder, axis, add, and prism eyepiece - ANSWER used to focus the lensometer Lens holder lever - ANSWER holds the lenses in place on the instrument spectable table lever - ANSWER used to raise or lower the glasses so the optical center is in the right position power drum (power wheel) - ANSWER dial used to read the lens power lens stop - ANSWER a lens is place against the lens stop when placed in the lensometer cylinder axis wheel - ANSWER used to find the axis of cylinder power Recticule - ANSWER series of concentric rings youll see when you look through the eyepiece of lensometer mire lines - ANSWER Perpendicular lines of three, used to calculate sphere and cylinder powers when provided a lens. Closely placed lines are the sphere, and wide lines represent the cylinder. circumference gauge - ANSWER a measuring tape that fits snugly around the lens perimeter and is measured in millimeters Focimeter - ANSWER an outdated term that may be used on your exam for the lensometer vertometer - ANSWER an outdated term that may be used on the exam for lensometer apex - ANSWER the tip of a triangle when drawing the prisms of plus and minus lenses in what directions does an image shift when light moves through a prism - ANSWER towards the apex Prentice's Rule Formula - ANSWER prism= power x decentration(cm) prism diopter - ANSWER A unit that describes the power of a prism to produce a 1-centimeter deviation in a ray of light at a distance of 1 meter from the lens slab off - ANSWER to corrects the client from seeing double from a vertical imbalance, youll use a slab off prism slab off is always done on the most minus, or least please in the vertical meridian reverse slab off - ANSWER reverse slab off is prefabricated at the lab to increase speed of delivery, it is applies to the most plus, or least minus lens, in the vertical meridian Rotating grip - ANSWER Used to determine the axis horizontal and vertical measuring drums - ANSWER Used for measuring horizontal and vertical corneal curvatures 337.50 - ANSWER The number to remember when converting diopters to millimeters cintacts lenses are usually fit to this curvature of the cornea - ANSWER flattest keratometer - ANSWER measures the front surface curvature of the cornea by providing the radii of curvature Corneal astigmatism - ANSWER the difference between the flattest and steepest curvature of the cornea Residual astigmatism - ANSWER if the corneal astigmatism does not match the prescription astigmatism, there is more astigmatism that is due to structures within the eye corneal topographer - ANSWER used to image and measure the entire corneal surface showing the locations, thickness, and depth as well as elevations and depressions Placido's disc or keratoscope - ANSWER illuminated target made up of concentric black circles reflected onto the cornea to measure the corneal surface intraocular lens implants - ANSWER Lens implants used in cataract surgery traditional gas permeable contact lenses - ANSWER usually considered hard contacts, but the materials are much more oxygen permable now, so they are now called gas permeable contacts scleral lenses - ANSWER large as permeable lenses made to cover the entire cornea OSHA - ANSWER Occupational Safety and Health Administration Osha standards - ANSWER standards and requirements to ensure that employers educate and make workers aware that they have the right to work in a safe environment and to be aware of potential workplace hazards and dangers Tempering - ANSWER hardening glass lenses to make them impact- resistant
