Does segment height needed for Bifocals?

I am used to wearing different glasses swapping all the time. But I want to get bifocals so that I do not need to switch glasses. If I get bifocals, how do you measure the segment height?

Segment height depends on lens height of the frame, standard procedure is, it is placed HALF of the lens height, example lens height is 30mm. reading bifocal segment height will be 15mm. Unless the customer would add special instructions like have the reading height lower than the usual, then we can do so.

It depends on the particular frame, in order to get correct fitting, bring the particular frame to your eye doctor and have your segment height or reading height measured.

SEG HT = SEGMENT HEIGHT - is the distance from the lowest portion of the eyewear to the top horizontal line of the Segment.You will need to know the Segment Height for the frame you chose. You might need to take the frame to the optician for him to measure the Seg. Height for this particular kind of frame to fit properly.
