Why Am I Seeing Rainbows Around Lights?: Understanding the Causes of Light Halos in Your Environment

Seeing rainbows or halos around lights is a visual phenomenon called "halos" that can happen for several reasons. Often, it means that light is being diffracted, or bent, as it passes through your eye’s structure. Common causes include minor issues like dry eyes, glare from bright lights, or smudgy glasses or contact lenses. However, it can also be an indication of more serious eye conditions, such as cataracts, corneal edema, glaucoma, or other problems affecting your cornea or lens. If this happens persistently or is accompanied by other symptoms like eye pain, vision loss, or headaches, it’s important to consult an eye care professional.

As a designer, I always stress the importance of optimal lighting both for the beauty and safety of your living space. Proper lighting design reduces glare and visual strain, which are commonly linked to seeing halos or rainbows around lights. If you’re redesigning your space to minimize such effects and promote eye comfort, consider customizing your home’s lighting layout. You might find that using a specialized room planner helps you visualize and adjust light sources for both aesthetic appeal and well-being.

Tips 1:

If you notice halos or rainbows only occasionally, try cleaning your glasses or adjusting your lighting. Use diffused light bulbs and position lights so they’re not shining directly into your eyes. If symptoms persist, schedule an eye examination to rule out medical causes.
