OPTICIAN STUDY GUIDE 2026 EXAM QUESTIONS AND
SOLUTIONS RATED A+
✔✔Critical Measurement to help a person who is Aphakic - ✔✔Vertex Distance
✔✔Name three frame mounting types that help to ensure that the lenses stay fixed in a
frame without using eyewires or nylon cords - ✔✔Rimless mounting, semi-rimless
mounting, and Numont mounting
✔✔Riding Bow temple - ✔✔This temple bends all the way around the ear and down to
the earlobe. This is a good choice for kids and safety glasses.
✔✔Comfort cable temple - ✔✔This temple is curved around the head, with the ends
bending around the ear all the way to the earlobe. The ear part of the frame is made of
a bendy spiral piece of metal.
✔✔Monel - ✔✔Alloy metal most often used in making frames. Made of 63-70% nickel. It
also contains copper and a trace of iron. This metal is resistant to corrosion, very
flexible, and whitish in color.
✔✔Titanium - ✔✔A metal alloy used to make frames that is very lightweight, strong, and
resistant to rust and corrosion. It is costly to manufacture and difficult to solder. Frames
made from this material are hypoallergenic, strong, and slender.
✔✔Stainless Steel - ✔✔An alloy composed of iron and chrome. This alloy is very pliable
and strong. This alloy is slender, very resistant to corrosion, and pliable.
✔✔Saddle bridge - ✔✔Shape of bridge that mirrors the shape of the nose and
distributes the weight of the frame more evenly.
✔✔Keyhole Bridge - ✔✔This shape of bridge is usually found on plastic frames. The
frames will touch the outside of the nose, but not the top of the nose. This would be
good for somebody with a short nose since more of the nose could be exposed and not
hidden by the bridge.
✔✔Comfort bridge - ✔✔This shape of bridge is for a metal frame, but the bridge is
made of translucent plastic.
✔✔Strap bridge - ✔✔This shape of bridge is for a metal frame, but the bridge strap is
plastic. It is on translucent piece instead of two separate ones. The weight of the frames
becomes balanced over the entire nasal area.
✔✔Skull temple - ✔✔The temple is shaped so that it mirrors the shape of the head. It
actually curves around the side of the head.
, ✔✔Library temple - ✔✔(Another name is straight-back temple.) These temples are
straight, with no curve, and they are wider at the back than in the front.
✔✔Convertible temple - ✔✔Flexible in nature, these temples are straight like library
temples, but can be changed to curve around the ear like a skull temple.
✔✔How much do you move the MRP for Pantoscoptic tilt? - ✔✔Move the MRP 1 mm
down for every 2 degrees of Pantoscoptic tint.
✔✔Which lenses need an MRP height measurement? - ✔✔Polycarbonate and Hi-index
✔✔How much space should you have around the bridge area for an appropriate fit? -
✔✔1 mm of space
✔✔Multifocal with a double segmented lens - ✔✔A bifocal lens with 2 segments that are
13-14mm apart. One of the segments is placed at the bottom of the lens and the other
segment is at the top of the lens.
✔✔Corneal Reflex pupillometer - ✔✔An instrument that accurately takes the pupillary
distance.
✔✔Chromatism - ✔✔The appearance of colored light.
✔✔Diffraction - ✔✔When light bends around things.
✔✔Reflection - ✔✔When some of the light bounces back to the original location. Can
cause a mirror image.
✔✔Options you should give your patients - ✔✔Lens types, Lens Materials and Options,
Frame styles, Contact Lenses, Accessories and any other product that would fit the
patient's needs and wants.
✔✔Dimensions you will need - ✔✔Measurements from facial features, measurements
for the eyes, and measurements for the frame.
✔✔Photochromatic - ✔✔These lenses turn darker outside when the UV rays hit the
lenses. Lower temperatures can also make then shade darker.
✔✔Holds the eyelid up with a droopy eyelid - ✔✔Ptosis crutch
✔✔Interference - ✔✔Can be two waves coming together to make a stronger wave, or it
can be two waves coming together and canceling each other out, causing destruction.
