Glasses vs Clothes vs Rain

Glasses are thin lenses for the eye to normalize and sharpen eyesight (some framed and some do not). Clothes are textile materials and fibers used as a cover body. Rain is a tangible liquid precipitation, in contrast to non-liquid precipitation such as snow, ice and rock slit. Who will win?

Glasses

Glasses are thin lenses for the eye to normalize and sharpen eyesight (some framed and some do not). Now besides being visual aids, glasses have become a complementary style as well as a special tool for enjoying entertainment such as three-dimensional special glasses.

Glasses of history was first started from Nero, a Roman emperor, ruling in 54 to 68 AD. Nero always use gemstones concave to read up to watch the show, although it is not known whether Nero has problems with his eyesight.

The Chinese people may be the first to use eyewear such as goggles that are commonly used today. Usually, the glasses are made of oval shaped lens is very large and made of rock crystal and the frame of a tortoise shell. In order to hold the glass, the Chinese use two wires by ballast and Anchored to their ear or strapped to cap the lens or using hooks Anchored to their temples. For the Chinese this time, the glasses are only used as a good luck charm or tools to make them look more cool and dignified, so sometimes they are just wearing frame glasses without lenses.

Today, sunglasses prevalent once using plastic lenses. This is due consideration to protect the user's eyes as a plastic lens is not easily broken compared with glass lenses. In addition, with the development of increasingly sophisticated technology, plastic eyeglass lenses was sought that did not experience the shattered so as not to endanger the eyes of users.

The use of goggles in contemporary times is no longer limited as visual aids. Currently, the glasses have become a fashion accessory that also developed rapidly. Not infrequently, the glasses become a special force for someone.

Clothes

Clothes are textile materials and fibers used as a cover body. Clothes are basic human needs besides food and shelter / residence (home). Humans need clothing to protect and hung up on her. But along with the development of human life, clothing is also used as a symbol of status, position, or the position of a person who wears it. Development and other types of clothing depends on mores, customs, and cultures that are typical of each. Clothes also enhance safety during hazardous activities such as hiking and cooking, by providing a barrier between the skin and the environment. Clothes also provides a hygienic barrier, keeping toxins from the body and limiting transmission of germs.

One of the main objectives of clothing is to keep the wearer feel comfortable. In hot climates clothing provides protection from sunburn or a variety of other impacts, whereas in cold climates thermal insulation properties are generally more important.

Clothing to protect parts of the body that are not visible. Clothes act as protection from damaging elements, including rain, snow, wind or other weather conditions, as well as from the sun. Clothes also reduce the level of risk during activity, like work or sport. Clothing sometimes worn as protection from specific environmental hazards, such as insects, noxious chemicals, weapons, and contact with abrasive substances. Conversely, clothing may protect the environment from the wearer clothes, such as wearing a mask.

Rain

Rain is a tangible liquid precipitation, in contrast to non-liquid precipitation such as snow, ice and rock slit. Rain requires the presence of a thick layer of the atmosphere in order to meet the temperature above the melting point of ice near and on the surface of the Earth. On Earth, the rain is the condensation of atmospheric water vapor into drops of water heavy enough to fall and usually arrive on the mainland. Two possible mechanisms can simultaneously push the air gets saturated before the rain, the cooling air or adding water vapor to the air. Virga is precipitation that falls to the earth but evaporates before reaching the mainland; This is one way of air saturation. Precipitation is formed through the collision between water droplets or ice crystals in clouds. Raindrops have sizes ranging from oblate, pancake-like (large grain), until a small ball (small grains).

Moisture moving along zones of temperature and humidity so-called three-dimensional weather fronts are the main method of rain production. If at that time there was moisture and sufficient upward movement, rain will fall from convective clouds (clouds with strong upward movement) such as cumulonimbus (thunderstorm) that can be collected into narrow bands of showers. In mountainous areas, heavy precipitation is possible where upslope flow increases on the windward side surface at a height that is forcing moist air to condense and fall as rain along the mountain side. On the leeward side of the mountains, the desert climate can occur because of the dry air caused the flow down the valley resulting in warming and drying air mass. The movement of the monsoon trough, or intertropical convergence zone, brings rainy seasons to savannah climes. Rain is the main source of fresh water in most areas of the world, providing suitable conditions for diverse ecosystems, as well as water for hydroelectric power generation and irrigation fields. Rainfall is calculated using a rain gauge. Total rainfall is calculated by weather radar actively and passively by weather satellites.
