Bifocal Round Type KT Lenses

What Bifocal Round Lenses Are

Bifocal Round Type KT (Kryptok) lenses are the classic bifocal design where a small round segment for near/reading vision is seamlessly fused into the lower portion of a distance vision lens. The KT (Kryptok) design features a circular near-vision area that blends smoothly into the main lens, making the bifocal line less visible compared to flat-top designs. This is the most time-tested bifocal format, used for over a century to help people with presbyopia (age-related difficulty in reading) see clearly at both distance and near without switching between two pairs of glasses.

Key Benefits

• See clearly at both distance and near with one pair of glasses
• Round segment blends more naturally into the lens than flat-top designs
• Proven, time-tested design trusted by optical professionals worldwide
• Most affordable bifocal option at just Rs 250
• No adaptation period needed for most users
• Eliminates the need to carry separate reading glasses

Who Should Use Bifocal Round Lenses

Bifocal Round KT lenses are designed for people with presbyopia — typically those aged 40 and above who need different prescriptions for distance and reading. If you find yourself holding your phone or book at arm's length to read, or if you currently switch between distance glasses and reading glasses, bifocal lenses will solve both needs in one pair. The round KT style is preferred by people who want a more discreet bifocal line.
