How Lights Look with Astigmatism: 1 Minute to Understanding Astigmatism Effects on Light Perception

For those with astigmatism, viewing lights—especially at night or in dim environments—can be a noticeably different experience. Instead of perceiving lights as pleasantly round or softly diffused, individuals often see streaks, halos, or starbursts radiating from light sources. This phenomenon occurs because the eye’s cornea or lens is irregularly shaped, causing incoming light to focus unevenly on the retina. Streetlights, headlights, and even illuminated screens may appear blurred or stretched in multiple directions, making nighttime navigation and reading more challenging. The distortion varies based on the severity and axis of astigmatism, and many describe seeing elongated "tails" of light that distract or hinder clarity.

Tips 1:

As a designer, I always consider lighting as one of the key elements in creating comfortable and accessible spaces. For people with astigmatism, glare reduction and proper layering of illumination are vital. When planning a room, soft ambient lighting and indirect fixtures help minimize harsh reflections and light distortion. If you’re looking to plan home or office lighting tailored to your needs, leveraging a room planner can ensure that your space supports visual comfort for all its users.

FAQ

Q: Does astigmatism make all lights appear blurry or streaky?

A: Many people with astigmatism see lights as blurred, streaked, or radiating, especially under low-light conditions.

Q: Why do I see halos around headlights at night?

A: Halos are a common symptom of astigmatism, caused by the irregular way the eye focuses light.

Q: Can proper lighting design reduce discomfort caused by astigmatism?

A: Yes, using layered lighting and reducing direct glare can greatly improve comfort.

Q: Will wearing glasses or contacts fix how lights appear with astigmatism?

A: Corrective lenses can minimize distortion, but may not eliminate all visual artifacts.

Q: Are there specific bulbs or fixtures recommended for people with astigmatism?

A: Soft, diffused lighting and fixtures that shield bulbs from direct view are best for minimizing glare and streaks.
