What is Direct Glare
Direct glare is a visual sensation caused by excessive and uncontrolled brightness in one’s field of view. It occurs when there is a significant contrast in brightness between different objects, resulting in a strong glare that can impede a person’s ability to perceive details and objects clearly. This type of glare is typically associated with high luminances or insufficiently shielded light sources, such as bright luminaires, ceilings, or windows, that are outside the visual task or region being viewed. It can also be caused by the direct visibility of the sun in front of a person’s eye.

Direct glare can have a significant impact on visual comfort and performance. It is important to minimize direct glare in lighting design to ensure optimal visibility and reduce visual discomfort. By properly shielding light sources and controlling luminance levels, designers can create a more visually comfortable environment that enhances the overall visual experience.
常見問題
What Is the Difference Between Direct Glare and Reflective Glare
Direct glare refers to the glare that occurs when the viewer looks at the ceiling area in front of them at angles shallower than 45°. On the other hand, reflective glare is the type of glare that directly affects the viewer’s vision in front of them, typically caused by luminaires in the ceiling area. It is important to note that reflective glare on screens is a specific instance of this type of glare.
What Causes Direct Glare
Direct glare occurs when an individual looks directly at a strong light source, such as a lamp or LED chip. This can result in discomfort and visual impairment. Reflected glare, on the other hand, is caused by light reflecting off highly reflective surfaces like computer screens or glossy surfaces.
亮度與眩光有何分別
眩光可描述為亮度的差異。為盡量減少眩光，可以在較暗區域與較亮物件形成對比時提高暗區亮度，或降低明亮區域（例如視野中的光源或其反射光）的亮度。
甚麼類型的燈泡可以減少眩光
作為現有能源效益最高的選擇，LED 燈泡和燈具在減少眩光及提升室內視覺清晰度方面極為有效。
看見燈光周圍有眩光稱作甚麼
看見燈光周圍出現光暈是一種稱為繞射的現象。當光線進入眼睛並發生折射時，就會產生繞射。雖然眼鏡和隱形眼鏡有時會引起繞射，但這亦可能是某些疾病的副作用。
What Eye Condition Causes Lights to Glare
Astigmatism is an eye condition that can result in blurry or distorted vision, headaches, and eyestrain. Individuals with astigmatism may experience increased glare around lights at night, leading to challenges while driving.
How Can I Reduce Glare Naturally
Consider adjusting the lighting in your space to reduce glare naturally. Instead of relying solely on overhead lights, try turning off some or all of them. If you require additional lighting for tasks like writing or reading, opt for an adjustable desk lamp. Additionally, make sure to close blinds or shades to minimize outside light sources. It is also advisable to avoid positioning your monitor directly in front of a window or white wall. Lastly, consider using an anti-glare cover for your screen to further reduce glare.
