How Multi-Focal Glasses Can Increase the Risk of Falling — And What You Can Do About It

Multi-focal glasses, including bifocals, trifocals, and progressive lenses, can be helpful for seeing both near and far. However, they also come with a downside: they may increase the risk of falls, especially in older adults.

In this article, I’ll explore a recent study on the link between multi-focal glasses and falls, explain why this happens, and offer practical strategies to stay safe.

The Link Between Multi-Focal Glasses and Falls

A 2025 study examined the relationship between different types of multi-focal lenses and fall risk in older adults. The research found that:

• Progressive lenses pose the highest risk for falls.
• Bifocals and trifocals also increase the likelihood of falling, though to a lesser extent.

The reason? Multi-focal glasses have multiple prescriptions in one lens, which can distort vision when looking down. This becomes particularly dangerous on steps, curbs, ramps, inclines, and uneven surfaces.

Why Do Multi-Focal Glasses Affect Balance?

Multi-focal lenses often create a “visual blur” in the lower portion of the glasses. This is problematic because we rely heavily on our lower field of vision for spatial awareness and balance.

Some people with vestibular disorders may experience dizziness when using these lenses. In such cases, switching to single-focal lenses for specific tasks may provide relief. While this may mean needing multiple pairs of glasses, it can significantly reduce discomfort and the risk of falling.

Practical Tips to Reduce Your Fall Risk

If you wear bifocals, trifocals, or progressive lenses, consider these strategies to stay safe:

1. Be Extra Cautious on Uneven Surfaces — Stay alert when navigating steps, curbs, ramps, and other changes in elevation.
2. Use Railings for Support — Holding onto a railing provides extra stability.
3. Adjust Your Gaze — When using stairs or walking on rough ground, tilt your head down so you’re looking through the top part of your lenses, which provides the clearest vision.
4. Lift Your Glasses if Necessary — In situations where you’re unsure of your footing, temporarily lift your glasses and look underneath to avoid the distortions of the reading portion.
5. Consider an Assistive Device — A cane or walker can provide additional balance and support.

Is It Time to Switch Glasses?

For those who struggle with balance or dizziness, switching to single-vision lenses for walking or outdoor activities could be beneficial. Some people opt to have multiple pairs of glasses — one for reading and another for mobility — to enhance both safety and comfort.

If you’re concerned about falls or are experiencing dizziness, speak to your eye doctor. They can recommend the best lens option for your specific needs.

By following these tips, you can reduce your risk of falling and maintain your independence while still benefiting from the convenience of multi-focal lenses.
