  Nope, in your case, the bifocal lenses are better than the progressive lenses. Because of the bifocal glasses are made with two different lenses power or prescriptions in one lens, the upper part of which features distance vision for myopia, and the lower part features near vision for presbyopia. This kind of glasses is suitable for your situation. However, the progressive glasses have many prescriptions in one single lens, which progress from the top to lowest part.

  Progressive lens are developed on the basis of the bifocal lens. The upper half of the bifocal lenses is designed to look far place, and the lower half is designed to observe close scene. but because of the difference between the lens radian, form the upper part and the lower part become two distinct parts, result to a clean line exist on the middle of the lense and make the appearance is poorer. What is more, the person who wear this kind of lense need to move up and down, the eyes must adjust the change sharply, then may causing fatigue or dizzy. But progressive lens use the grinding technology to solve the problem, the two focal transit gradually, make the wearer adust the change gradually too and he or she will feel more comfortable. What is more, the obvious dividing line disappear as well. Comparative perspective, I recommend you use progressive lens.

  The bifocal lenses help you see the near things through the lower part and the far things from the above part of lenses. However, the progressive eyeglasses will divide a lot of regions for your eyes to look, with the basic principle of bifocal eyeglasses. But its more divided region may help you eyes get adapted comfortable after the change of seeing from the near things into the far things. In my own opinion, I think the progressive eyeglasses are the better choice for you.

  Progressive lenses will offer a %u201Cyounger-looking%u201D appearance but also give all the advantages of bifocal and trifocal lenses. But there are advantages and disadvantages with progressive lenses just like any other product that has been recently discovered. To the wearer of _a href="http://www.precisionoptics.com.au/lenses-and-coatings/"_progressive lenses_/a_ the transition among the vision lines is very smooth. With other lenses, such as bifocals or trifocals, the reader must get used to looking through the top, middle, or bottom to be able to see a certain distance, but with progressive lenses there is no exact dividing line so it appears to them as if their vision in perfect. At the same time Progressive lenses can cause distortion in the wearer%u2019s peripheral vision because in order to create the central progressive zone into the lens you have to create areas of distortion in the peripheral areas of the lens. In order to assure that the wearer will get used to the progressive lenses, the glasses require careful placement relative to the wearer%u2019s pupil center.

  The progressive lens gives you the intermediate distance also that a bifocal can't do. The reading area of a bifocal is always going to be wider than in a progressive, and the distance porion of the lens is normally clear right to the outer edge of the lens.
  
  With the bifocal, if you are standing at a desk, you can't read a note on the desk without picking it up to bring it within the fixed focal distance of your reading segment. With the progressive, you can, because you have the intermediate power also to be able to focus at any distance.
  
  Most progressives will blur out at some point on the outer edges of the lens in the distance portion, however the brain gets used to that and it doesn't bother most people for long.
  
  Truck drivers have trouble with progressives because of that, with the side mirrors they have to glance at all the time on both sides.
  
  The reading area of the progressives is also narrower than with a regular bifocal, therefore you have to move your head more, not just your eyes to read across an open newspaper.
  
  If this is going to be your first time wearing either, then the progressive is the best way to start. Once you get used to it, it is more like normal vision because of that intermediate portion.
