Progressive lenses, also known as multifocal lenses, are corrective lenses used in eyeglasses to correct presbyopia. It may also help in correcting other eye disorders too. Progressive lens provides you three vision powers in one smoothly designed lens for a more flattering and natural way to see your world. If you need more than one lens strength to read, work, or drive, progressives lenses let you see clearly at any distance with one pair of glasses.
Progressive lenses provide you a smooth, seamless, continuous field of vision, replacing the need for multiple pairs of glasses for different tasks and activities. They also help in increasing the edge-to-edge clarity and provide full-range vision correction at different distance ranges.
Are Progressive Lenses the Same as Bifocals?
Bifocals have just two lens powers whereas progressive lenses are multifocal lenses that offer a progression of many lens powers. This provides continuous vision without any hurdle, eliminating a major issue caused by bifocals that is “image jump.”
A bifocal lens is created with two different areas of vision correction having bifocal lines which divides the lens into two portions. The top portion of the lens is used to look at distances while the bottom portion of the lens is used to look closer.
Progressive lenses, however, are also known as no-line bifocals. They provide multiple ranges of vision that varies from distant to near without a line across the lens. They have an intermediate distance range that is best for computer usage.
Are Progressive Lenses Hard to Get Used to?
It is not hard, but yes it takes time to get used to it. When you are fitted first time with the pair of progressive lenses, it may take a while for adaption to become comfortable with it. This might take only a few minutes or a few days.
Can Progressive Lenses Cause Problems Such as Headaches or Migraines?
Progressive lenses are not directly linked to headaches or migraines, whereas blurry vision can be a cause of a headache. Blurry vision can be due to using lenses with incorrect strength. In case of progressive lenses, if you look down you might notice your vision is slightly blurred. That is because of peripheral aberrations and doesn’t necessarily result in a headache. When you get used to wearing progressive lenses, you can usually get rid of them by making slight head movements to look directly at objects.
