What’s the difference between multifocal and bifocal lenses?Updated a month ago

At Nooz, we offer two types of lenses for presbyopia: multifocal lenses (also called degressive) and bifocal lenses. While they serve similar needs, they work quite differently.

🔄 Multifocal lenses (degressive)

These lenses offer a gradual reduction in correction from the bottom to the top:

🔽 Bottom part: strong correction for reading

🔼 Top part: lighter correction for intermediate vision (up to around 3 meters)

✅ Perfect for:

• Reading
• Computer work
• Talking and interacting with others

⚠️ Limitation: not suitable for long-distance vision

👓 Bifocal lenses

These lenses have two clearly separated zones:

👁️‍🗨️ Bottom zone: with correction for close-up reading

🆓 Top zone: without correction – for seeing far away

✅ Perfect for:

• Outdoor activities or walking
• Switching quickly between reading and distance viewing
