I have bifocal glasses, but I don't wear them because of the line. when I wear them I often get dizzy up and down stairs, and if I look straight ahead, the line is in the middle of my vision. I cann't bear all these. who can help me to figure out why this happens?

You don`t have to be bothering about this ,because every bifocal glasses are the same .If you really can not stand this ,you can substitute a pair of progressive eyeglass for your bifocal eyeglass,but progressive eyeglass need time to adjust at the beginning you wear it.

Progressive Lenses are also called as no-line bifocals, they are the good choice for you. PrescriptionGlassesOnline.net is an online optical store, they supply progressive glasses starting from USD46.45.

Hello, I have never purchased glasses online before. I wear progressives(no line) & would like to actually be able to own more than 1 pr. of glasses at a time therefore looking for cheap!of course still wanting modern, up-to-date frames. I tried looking on your Daily Special Prescription Eyeglass section but it seems most of those are single vision. Is that correct? Also is there a way of looking for women's, progressives, half rim all at the same time? Thanks.
