Determine where adjustments are needed
Stand in front of the mirror and look straight ahead. Let the center of the lens be in the center of the eye. This point is the optical center and the ideal position for the fake oakleys, so any adjustments to the glasses should be based on this position.
With bifocals, this line should be flush with the lower eyelid; with trifocals, the top line should be aligned with the bottom of the pupil.
Check to see if there is a problem with the temples.
If the glasses are bent or tilted to one side, it may be caused by bent temples. The way to test the temples is to place the glasses upside down on a flat surface, normally each temple should lie flat. If not, they need to be adjusted.
If the glasses are flat on the face, but curved on a flat surface, it may mean that one of your ears is taller than the other, so you need to adjust the temples to accommodate different ear heights.
Check to see if there is any problem with the bridge of the nose.
Observe the height of the glasses when you wear them. If the lenses are too high or too low, it may be because of a problem with the bridge of the nose. At this time, you need to adjust this part.
Check for pinching or slipping issues.
Even when the glasses are centered and at the correct height, they can still be too loose or too tight. You can adjust the temples as needed to adjust the tightness of the glasses, preferably from the hinge position. Bending the temples outwards reduces pressure on the head or temples, while bending inwards allows the glasses to fit better on the head.
Look for where it slipped. You may find that the glasses slip off even though everything else looks fine. If this is the case, simply adjust the screws that attach the temple to the lens.
Adjust the balance frame.
The temples extend back from above the ears to hold the frame in place. In addition to determining what needs to be adjusted, consider differences in eyeglass styles. Because the frame material is different, the method of correcting the problem will also be different.
The fake oakley sunglasses frame can be adjusted slowly with small pliers until the frame is straight. Look in the mirror after putting on the glasses to see if they are normal.
Do not use wire cutters.
Padded pliers must be used, otherwise the frame may be damaged.
For the plastic frame, use warm air from a hair dryer underneath to soften the plastic. Then slowly adjust it upwards by hand until it is in the correct position. Be careful with the blow dryer to prevent the plastic from melting.
Another way to bend a plastic frame is to scald it in hot water for about 20 seconds before making adjustments. At this point the bezel will be flexible enough to be easily adjusted, but be careful as the plastic can also break easily at high temperatures.
