The document discusses various tools used for optical repairs, including different types of optical screwdrivers, flaring pliers, and screw-lift tools. It also describes the different types of nose pad assemblies, including screw-on and push-on pads. The document provides guidance on replacing broken parts like temples, plastic earpiece covers, and nose pads on frames. It notes that soldering, either with a flame or electric unit, is usually required to repair broken metal portions of frames.
2. Most necessary repairs will be minor.
As a result, replacement of broken parts is
usually more cost effective.
3. Correctly Using an Optical Screwdriver
When using an optical screwdriver, the
screwdriver should not be held like a pencil.
There are many different types of optical
screwdrivers available, from ones with brass
shafts and no-roll handles, large, round
hardwood handles that fill the palm of the
hand.
6. The screw-holding tool places the screw in
hard-to-reach places where fingers cannot always go.
7. Flaring pliers will flare a rivet or screw tip to
prevent it from backing out.
8. The screw-lift tool allows a loosened screw to
be removed with less chance of being dropped.
9. There are many different types of nose pad
assemblies.
The screw-on and push-on type nose pad
assemblies are the most dominant.
10. The push-on pad is one of the easiest pads to
remove and replace.
It has a small I-beamlike shape that snaps into
an indented box on the pad arm.
Although a push-on pad can be removed without
the aid of tools, it is possible to use a small
device called a pad popper.
12. The screw-on type of attachment has a small
post on the back of the pad with a horizontal
hole in the post.
13. Replacing Missing or Broken Temples
If a pair of glasses has an irreparably
broken temple, it must be replaced. The first
choice is to replace it with a new, identical
temple.
14. Replacing the Plastic Earpiece Covers on Metal
Temples
Covering the Temples to Reduce Allergic
Reactions
15. Broken Plastic Bridges
Replacing Nose pads on Plastic Frames
16. Soldering is the only possible way to repair a
broken metal portion of a frame unless the
entire front or temple is replaced.
Flame Soldering
Some flame soldering units use one gas, butane.
Others use two independently regulated gases,
either oxygen and acetylene or oxygen and
butane. The oxygen will be used up at twice the
rate of either the acetylene or the butane.
