Types of reading

Extensive Skimming Skimming is sometimes referred to as gist reading.

Woman wearing sunglasses Sunglasses provide improved comfort and protection against bright light and often against ultraviolet UV light. To properly protect the eyes from the dangers of UV light, sunglasses should have UV blocker to provide good coverage against the entire light spectrum that poses a danger.

The dark tint of the lenses in a pair of sunglasses blocks the transmission of light through the lens. Light polarization is an added feature that can be applied to sunglass lenses. Polarization filters are positioned to remove horizontally polarized rays of light, which eliminates glare from horizontal surfaces allowing wearers to see into water when reflected light would otherwise overwhelm the scene.

Polarized sunglasses may present some difficulties for pilots since reflections from water and other structures often used to gauge altitude may be removed. Liquid-crystal displays often emit polarized light making them sometimes difficult to view with polarized sunglasses.

Types of reading may be worn just for aesthetic purposes, or simply to hide the eyes. Examples of sunglasses that were popular for these reasons include teashades and mirrorshades.

Many blind people wear nearly opaque glasses to hide their eyes for cosmetic reasons. Sunglasses may also have corrective lenses, which requires a prescription. Clip-on sunglasses or sunglass clips can be attached to another pair of glasses.

Some wrap-around sunglasses are large enough to be worn over top of another pair of glasses. Otherwise, many people opt to wear contact lenses to correct their vision so that standard sunglasses can be used. Mixed doubleframe[ edit ] Doubleframe eyewear with one set of lenses on the moving frame and another pair of lenses on fixed frame optional.

The doubleframe uplifting glasses have one moving frame with one pair of lenses and the basic fixed frame with another pair of lenses optionalthat are connected by four-bar linkage.

For example, sunlenses could be easily lifted up and down while mixed with myopia lenses that always stay on. Presbyopia lenses could be also combined and easily removed from field of view if needed without taking off glasses. The signal, often light reflected off a movie screen or emitted from an electronic display, is filtered so that each eye receives a slightly different image.

The filters only work for the type of signal they were designed for. Anaglyph 3D glasses have a different colored filter for each eye, typically red and blue or red and green. A polarized 3D system on the other hand uses polarized filters. Polarized 3D glasses allow for color 3D, while the red-blue lenses produce an image with distorted coloration.

Consider word function when you are looking for a verb.

An active shutter 3D system uses electronic shutters. Head-mounted displays can filter the signal electronically and then transmit light directly into the viewers eyes. Anaglyph and polarized glasses are distributed to audiences at 3D movies. Polarized and active shutter glasses are used with many home theaters.

Head-mounted displays are used by a single person, but the input signal can be shared between multiple units. Magnification bioptics [ edit ] Glasses can also provide magnification that is useful for people with vision impairments or specific occupational demands.

An example would be bioptics or bioptic telescopes which have small telescopes mounted on, in, or behind their regular lenses. Newer designs use smaller lightweight telescopes, which can be embedded into the corrective glass and improve aesthetic appearance mini telescopic spectacles.

They may take the form of self-contained glasses that resemble goggles or binocularsor may be attached to existing glasses. They perform minor color correction, on top of reducing headaches due to lack of blinking.

They may also be considered minor corrective unprescribed glasses. This allows for reduced eye-strain. The lenses are given an anti-glare coating to prevent reflections of light under different lighting conditions. By reducing the amount of glare on your eyes, vision can be improved.
