Progressive Lenses:
Progressive lenses are identical to normal single vision lenses. These hi-tech lenses offer one of the best technologies and smoothest transitions at near, distant as well as middle vision with no unattractive lines.

Presbyopic patients find progressive lenses offer the most natural vision at any lengths. Sophisticated and advanced progressive lenses are far better than bifocals or trifocal lenses. These lenses offer a seamless progression from distance to near with an intermediate section in between for easy progressions from near to far as well as vice versa. A single progressive lens can help you drive your car or help you inside your home in reading too.

Bifocals:
After 40 years of age most adults feel they need to strain their eyes and hold out books farther to read the text properly and require special vision correctors. Though many people today are going for multifocal lenses, the Bifocal lenses do have their own advantages and disadvantages.

There are many types of bifocal lenses but all of them have two power lenses merged into one single lens. Most of these lenses are prescribed for presbyopic patients. Here are the types of Bifocal lenses you will come across while looking out for Bifocal lenses.
• Flat Top Bifocal Lens (D Segment or Straight Top Bifocals): Here there is a half moon position or segment devoted to near vision correction.
• Round Segment Bifocals : A round segment in the lens which is the area for the near vision correction
• Executive Bifocal Lens (Franklin Bifocal): The lens has two distinct parts, where the bottom part is devoted to near vision.
• Ribbon Segment Bifocals: A narrow segment devoted to the near vision, leaving the maximum segment for distance vision.

Reading Glasses:
Reading glasses are single vision glasses but specially meant to aid in viewing close objects. With age eyes lose their elasticity and the power to focus on nearby objects and this creates the need to stretch their arms to view close objects. But with age there is the need to wear special glasses to see better at the arm’s length. Bifocal glasses come in two varieties. The first style is the full frame bifocal glasses where the total lens offers the reading prescription.

The second type of reading glasses offer half eyes style eyeglasses that sit lower on your nose and are called ‘Ben Franklin’ style reading glasses. While wearing reading glasses if one wants to look across the room it would be better off through the half eye reading glasses.

These are the major differences among the Reading glass, progressive lens and bifocals. Now we hope you will find it easie
