A: Dear Gladys Desarden, Thank you for your quick response. We can remake one pair of glasses for you first. Thhen if the remade one is no problem, then we\'ll remake the other glasses, could you accept this?
if you can accept,could you measure your sister\'s SEG height according to the following steps:How to Measure Your Segment Height
1. Use a ruler that has millimeter measurements. You can also use a ruler with centimeter measurements and simply times the result by 10 to get your millimeter measurement.
2. Put the glasses on your face and adjust them so that they sit comfortably.
3. Stand about 8 inches (20 cm) away from a well lit mirror with your face parallel and square to the mirror.
4. Align the ruler\'s zero (0) measurement to the lowest point at the bottom of your lens, keeping it exactly vertical. Make sure you are measuring from the bottom of the clear lens, not the bottom of the frame (see graphic above).
5. Stare straight ahead and read the millimeter line that lines with the center of your pupil. This is your segment height measurement for these frames.
6. Repeat these steps at least 3 to 5 times to get an accurate and consistent measurement. Make sure your head and the ruler do not move after lining up the zero (0) measurement with the bottom of your lens until you note your measurement. Ask a friend to help if you are having trouble.
