Single Lens Glasses - Fall Prevention

Multi-focal glasses - bifocals, trifocals and progressives - are good for tasks that require you to adjust your focus from distant to near objects, such as when driving or reading. When it comes to walking, however, especially outdoors, multi-focal lenses may not be your best bet. 

Outdoor terrain isn't always even, and glasses with multiple lenses may blur your vision when you look down at the ground to avoid obstacles.

In a study that observed 600 multi-focal wearers who averaged 80 years old, half were asked to switch to single-lens glasses when going outside. Participants who spent the most time outdoors reduced their falls by 40 per cent after making the switch.

If you spend a significant amount of time outdoors and wear multifocal lenses, including bifocals, consult your eye-care professional about single-lens glasses for outdoor activities.
