Most of the senses of sight are concerned with seeing. A wonderful spectacle might be described as a sight, as might the general capacity to see anything ("my sight is not as good as it once was"). Sight is also used in a number of fixed phrases, such as "out of sight, out of mind," "sight unseen," and "set one's sights on." Sight comes from Old English gesiht, meaning "the faculty or act of sight, thing seen."

At its simplest, a sight typically has two components, front and rear aiming pieces that have to be lined up. Sights such as this can be found on many types of devices including weapons, surveying and measuring instruments, and navigational tools.
On weapons, these sights are usually formed by rugged metal parts, giving them the name "iron sights", as distinct from optical or computing sights. On many types of weapons they are built-in and may be fixed, adjustable, or marked for elevation, windage, target speed, etc. They are also classified in forms of notch (open sight) or aperture (closed sight). These types of sights can require considerable experience and skill, as the user has to hold proper eye position and simultaneously focus on the rear sight, the front sight, and a target, all at different distances, and align all three planes of focus.
A telescopic sight is a refracting telescope equipped with some form of referencing pattern (reticle) mounted in an optically appropriate position in the optical system to give an accurate aiming point. Telescopic sights are used on a wide range of devices including guns, surveying equipment, and even as sights on larger telescopes (called a finderscope).
Another type of optical sight is the reflector (or "reflex") sight, a generally non-magnifying optical device that allows the user to look through a glass element and see a reflection of an illuminated aiming point or some other image superimposed on the field of view. These sights have been around for over 100 years and have been used on all types of weapons and devices.
Reflector sights were first used as a weapon sight in German aircraft towards the end of World War I. Over the years they became more sophisticated, adding lead computing gyroscopes and electronics (the World War II Gyro gunsight) radar range finding and other flight information in the 1950s and 60s, eventually becoming the modern head-up display.

This article is intended for enterprise admins and IT Pros who manage security settings for organizations. If you are not an enteprise admin or IT Pro but you have questions about block at first sight, see the Not an enterprise admin or IT Pro? section.
Block at first sight is a threat protection feature of next-generation protection that detects new malware and blocks it within seconds. Block at first sight is enabled when certain security settings are enabled. These settings include:
Block at first sight only uses the cloud protection backend for executable files and non-portable executable files that are downloaded from the Internet, or that originate from the Internet zone. A hash value of the .exe file is checked via the cloud backend to determine if the file is a previously undetected file.
You can confirm that block at first sight is enabled on individual client devices using the Windows Security app. Block at first sight is automatically enabled as long as Cloud-delivered protection and Automatic sample submission are both turned on.
You might choose to disable block at first sight if you want to retain the prerequisite settings without actually using block at first sight protection. You might temporarily turn block at first sight off to see how this feature affects your network. However, we do not recommend disabling block at first sight protection permanently.
If you are not an enterprise admin or an IT Pro, but you have questions about block at first sight, this section is for you. Block at first sight is a threat protection feature that detects and blocks malware within seconds. Although there isn't a specific setting called "Block at first sight," the feature is enabled when certain settings are configured on your device.
If you have a personal device that is not managed by an organization, you might be wondering how to turn block at first sight on or off. You can use the Windows Security app to manage block at first sight.

After treating nearsightedness and astigmatism with the Wavelight laser, night vision clarity after treatment is actually better on average than before treatment. LASIK technology, combined with our surgical expertise makes it possible to correct a very wide range of optical imperfections.
New Lifestyle Intraocular Lenses (IOLs) can correct nearsightedness, farsightedness, and astigmatism; affording the ability to see well at distance after treatment, without glasses. Other special multifocal lenses allow focus at a fuller range of vision, reducing or eliminating the need for glasses at any distance. We personalize our recommendations to you based on your lifestyle, visual desires, habits, and preferences during a comprehensive evaluation.

According to Johnson & Johnson Vision, Myopia, often called nearsightedness, is commonly understood as the inability to see far away objects clearly without glasses or contact lenses. It is, in fact, much more than that. Myopia is a chronic progressive disease where continued eye growth not only worsens distance vision, it also increases future risk of sight-threatening complications. 041b061a72
