Yes, bifocal glasses with the upper part for computer use, lower part for reading can meet your demands.First, your recent RX is needed. (make sure your SPH power, near PD/ far PD, ADD are all included). Second, choose the frame that can be made into bifocals/progressives. (usually the frame height is greater than that of single vision lenses). Third, state clear or choose the right usage of your glasses( bifocals for both reading and computer use).
