With bifocal lenses you can only see up-close and far away; any objects in between remain blurry. A bifocal lens is simpler in construction than a progressive lens and in essence combines two single vision lenses. The lens has a distinguishable near-sighted part. The majority of users are wearers over the age of 40 who need various adjustments for distance and close-up viewing.
Bifocal lenses are now also made using freeform technology, which focuses even more on aesthetics and in the case of which the near-sighted part of the lens no longer looks like a ‘window’, but visually resembles a single vision or progressive lens.
Bifocals can be ordered with photochromic properties, tinting and coatings.
