What are the two main types of glare?

The two main types of glare are best classified as direct glare and reflected glare. Direct glare occurs when there is a bright light source that shines directly into the eyes, causing discomfort and reducing visibility. This type of glare can be experienced from various sources, such as sunlight shining directly into a person's line of sight or artificial lighting that is too intense.

Reflected glare, on the other hand, arises when light bounces off surfaces and creates a bright spot in a person's field of vision. Common examples include sunlight glinting off water, glass, or shiny surfaces. This can also lead to visual discomfort and can significantly hinder visibility, especially during tasks that require precision.

By understanding these two types of glare, those in the optical field, particularly in a retail setting like Walmart, can better assist customers by discussing options for lenses and coatings that can mitigate glare-related issues, enhancing visual comfort and clarity for their clients.
