A bright, dazzling light; splendor that dazzles the eyes; a confusing and bewildering light.
A smooth, bright, glassy surface; as, a glare of ice.
Smooth and bright or translucent; -- used almost exclusively of ice; as, skating on glare ice.
The discomfort or interference with visual perception when viewing a bright object against a dark background.
A condition where the patient sees additional luster around lights.
Bright lighting that causes discomfort and impairs good visibility. Possible causes may be light sources that are too bright for the application, or fixtures that may not conceal bulbs sufficiently, among many others.
Condition of vision in which there is discomfort or a reduction in the ability to see significant objects, or both, due to an unsuitable distribution or range of luminance or to extreme contrasts in space or time.
Glare is any unwanted light that causes discomfort, interference with vision, or eye fatigue. Direct glare is caused by light coming directly to the eye from a source or bright surface. Discomfort or reflected glare is light reflected from a surface in the direction of the eye.
The temporary loss of vision due to exposure to a bright light source. Vision returns to normal soon after the light source is turned off. There may be a transitory (1 to 2 second) after-imaging.
An unpleasant quality of hardness or brightness, due to excessive low- or mid-treble energy.
Term describing the effect of unwanted light falling on a surface or affecting normal vision. Commonly identified as a problem where VDUs are used and reflections of luminaires can be seen in VDU screens.
Any hindrance to vision caused by the scattering or reflection of light into an observer’s line of sight.
Glare is often felt by motorists at night when your pupils adjust to the darkness. A passing car with high beams will cause momentary blindness because of your eyes night time state. Home and business lighting can have the same effect on motorist's eyes. By aiming lights downward or using a visor, glare can be prevented.
Brightness in the field of view that exceeds the luminance to which the observer has adapted, and may result in annoyance, discomfort, or degraded visibility.
Intense and blinding light. Never helps visibility.
intense light into the eyes causing discomfort.
Glare results from areas of high brightness in the visual field and can cause discomfort, irritation and obscuration of the message.
uncomfortably bright light not including dangerous degrees of ultraviolet or infrared light.
Extraneous light from any source can affect visual performance. Glare may reduce contrast and cause a decrease in visual acuity.
Glare is too much light for the eyes to handle comfortably and efficiently. Glare can come directly from a light-source or it may be reflected. Most often, glare is a combination of bright overall direct light and reflections.
Complication of refractive surgery in which scatter from bright light decreases vision
great brightness; "a glare of sunlight"; "the flowers were a blaze of color"
be sharply reflected; "The moon glared back at itself from the lake's surface"
See direct glare, disability glare, discomfort glare, reflected glare.
A common complication of a LVC procedure where a patient may see additional luster around lights. It is often a subjective phenomena that usually decrease over time.
Visual discomfort caused by excessive brightness is called discomfort glare. If task performance is affected it is called disability glare. Glare can be direct glare or indirect (reflected) glare.
The sensation of being dazzled by direct light.
(lighting) Glare occurs when one part of the environment is much brighter than the general surrounding area. The contrast causes the eye to have to continually adjust and is tiring and stressful.
When a portion of the visual field has a significantly higher luminance than its surroundings, resulting in reduced contrast
Excessive brightness that may be caused by either direct of indirect viewing of a light source.
A complication of refractive surgery that causes points of light of look brighter and less distinct
Caused by a direct light source (the sun) or is reflected from a surface (roadway, water). Your eyes can be subjected to more than 10 times the level of light you need to see. When it reaches these levels it will become physically painful.
Stray or scattered light within the microscopical system; extraneous light from windows or lamps; light scattered by the specimen that masks image detail and prevents thorough observation. An under- or over-corrected objective or condenser also may cause glare.
Glare is the discomfort caused by high luminances in the field of vision.
is scatter from bright light that decreases vision.
A source of uncomfortably bright light that becomes the focus of attention rather than what it was meant to illuminate.
The loss of visibility and/or the sensation of discomfort associated with bright light within the field of view. See also direct glare and reflected glare.
A sensation caused by light within the visual field that is brighter than the level of light to which the eyes are adapted, causing annoyance, discomfort or loss in visual performance.
over abundance of light on a particular surface
water that reflects light on the surface making it nearly impossible to see below the surface without the aid of polarized glasses. It can inhibit the ability to take photographs substantially. Even on cloudy overcast days you can experience glare.
scatter from bright light that causes discomfort and can decrease vision and the ability to perform tasks like driving.
A complication of refractive surgery in which the patient sees additional luster around lights. Glare is a subjective experience that often decreases with time.
An undesirable property of light; any brightness from a light source within the field of vision that causes viewer discomfort. This problem is sometimes referred to as direct glare.
There are two sorts of glare – discomfort glare and disability glare. The mechanisms of both are unknown, but the conditions under which discomfort glare occurs and the ways in which disability glare can affect performance are well known. Discomfort glare : When a portion of the visual field has a much higher luminance than its surround, a feeling of discomfort around the eyes and brow may occur. This increases with an increase in the luminance of the glare source, and with an increase in the angular size of the glare source at the eye, and decreases with an increase in the luminance of the background and with an increase in the angular position of the source relative to the line of sight. Disability glare : An extraneous light source can affect visual performance. The problem with disability glare is that it reduces contrast, causing a washing out – the whole scene looks grey. Like discomfort, the disability glare is often reduced by increasing the light level. Think about a car's headlights on full during the day; there's lots more light, and as a result, the car's headlights are less of a problem.
A very bright light or a high contrast of light making it uncomfortable or difficult to see.
The effect of brightness or differences in brightness within the visual field sufficiently hiah to cause annoyance, discomfort or loss of visual performance.
Unwanted brightness in the field of vision. Also see Direct Glare and Reflected Glare.
A negative term describing uncontrolled light that produces discomfort to the viewer.
Direct glare Is caused by light coming directly to the eye from a source or bright surface. Reflected glare is light reflected from a surface in the direction of the eye. Both can harm vision and cause discomfort or disability.
A term that is typically used to describe light sources that produce a sensation of discomfort, a loss in object visibility, or both.
The impairment or discomfort of vision experienced when parts of the visual field are excessively bright in relation to the general surroundings.
An excessively bright light that causes discomfort and vision impairment. May be direct or indirect (from a reflection).
Excessive brightness in the field of view.
The sensation produced by luminance within the visual field that is sufficiently greater than the luminance to which the eyes are adapted to cause annoyance, discomfort, or loss in visual performance and visibility.
Light sufficiently intense to cause physical discomfort or to reduce contrast below the level at which detail is discernible.
Glare is difficulty seeing in the presence of bright light such as direct or reflected sunlight or artificial light such as car headlamps at night. Because of this, some cars includes mirrors with automatic anti-glare function.
