What Is Glare?

Are you curious to know what is glare? You have come to the right place as I am going to tell you everything about glare in a very simple explanation. Without further discussion let’s begin to know what is glare?

In our visually-oriented world, light plays a central role in how we perceive our surroundings. However, not all light is created equal, and at times, it can lead to discomfort and even temporary vision impairment. This phenomenon is known as glare. In this blog post, we will delve into the concept of glare, its causes, types, and the ways it affects our daily lives.

What Is Glare?

Glare refers to the excessive and uncontrolled brightness of light that causes visual discomfort and reduces visual clarity. It occurs when there is a significant difference in luminance (brightness) between different areas in our field of vision. Glare can manifest in various environments, from natural sunlight to artificial lighting, and can occur indoors or outdoors.

Causes Of Glare

  • Direct Glare: Direct glare is caused by an intense light source that falls directly into the eyes, making it difficult to see clearly. Examples include looking directly at the sun or facing headlights of oncoming vehicles at night.
  • Reflected Glare: Reflected glare occurs when light reflects off surfaces such as water, glass, or shiny objects, creating bright spots that hinder visibility.
  • Disability Glare: This type of glare occurs when light scatters within the eye due to factors like cataracts or other eye conditions, leading to reduced visual clarity.

Types Of Glare

  • Distracting Glare: Distracting glare is mild and doesn’t necessarily affect vision significantly, but it can still be bothersome. An example is glare from a computer screen or glossy surfaces.
  • Discomfort Glare: Discomfort glare causes discomfort and can lead to visual fatigue. It can occur when a bright light source is within the field of vision but not directly in the line of sight.
  • Disabling Glare: Disabling glare is severe and impairs vision to the extent that tasks become difficult or impossible. Examples include driving at night with blinding headlights or working in direct sunlight without proper protection.

Impact On Daily Life

  • Driving Safety: Glare from oncoming headlights, especially at night, can hinder visibility and lead to accidents.
  • Outdoor Activities: Glare from the sun can cause squinting, eye strain, and difficulty seeing objects clearly, impacting outdoor activities like sports and relaxation.
  • Workplace Productivity: Glare from computer screens, overhead lights, or reflective surfaces can reduce concentration and productivity in indoor environments.
  • Visual Comfort: Glare-free environments promote visual comfort and reduce eye strain, contributing to overall well-being.

Managing Glare

  • Proper Lighting: Using diffused lighting instead of direct sources can help minimize glare.
  • Anti-Glare Coatings: Coatings on eyeglasses, screens, and windows can reduce reflected glare.
  • Adjustable Lighting: Adjusting the angle and intensity of light sources can help control glare.
  • Proper Shades: Wearing sunglasses with proper UV protection outdoors can shield the eyes from glare caused by sunlight.


Glare is a common phenomenon that impacts our visual comfort and clarity. By understanding its causes, types, and effects, we can take steps to mitigate its impact and create more visually comfortable environments. Whether indoors or outdoors, minimizing glare enhances our overall quality of life and promotes healthier and more comfortable vision.
