A general view on Glasses

The Glasses, spectacles, or eyeglasses are frames manner lenses worn in front of the human eyes, sometimes for just aesthetic reasons but in general for vision correction or eye protection. The Special glasses are used for viewing the three-dimensional images or experiencing virtual reality.
The Modern glasses are typically supported by pads on the bridge of the nose and by temples placed over the ears. The Historical types consist of the pince nez, monocle, and lorgnette. The Glasses are more often called eyeglasses in North American English, rarely spectacles in British English, and (rarely) frames or lenses. The Spectacles are often shortened to specs. In hipster jargon they are cheaters.
The Glasses were initially made from glass, but many are now made from plastic (often polycarbonate) because of the danger of breakage and the greater weight of glass lenses. Some plastics also have more beneficial optical properties than glass, like better transmission of visible light and better absorption of ultraviolet light. Some plastics have a greater index of refraction than the majority types of glass, allowing thinner lenses for a given prescription. Scratch-resistant coatings can be applied to most plastic lenses charitable them similar scratch resistance to glass. Hydrophobic coatings intended to ease cleaning are also obtainable, as are anti-reflective coatings designed to improve night vision and make the wearer's eyes more visible.
The Corrective spectacles have lenses created to correct vision abnormalities, like myopia. The Safety glasses are a type of eye protection against flying debris or noticeable and near visible light or radiation. The Sunglasses care for against high levels of visible and ultraviolet light.

Hello,

My name is Arman Nafisi-Movaghar and I am currently doing an undergraduate honors research study for the Department of Communication at the University of Washington on blogs by Iranians living outside of Iran. I am interested in seeing how Iranians in the diaspora are using their blogs and specifically if they are promoting democratic values on their blogs. To help answer this question, I created a survey for Iranian bloggers living outside of Iran to complete. Since you are an Iranian living outside of Iran who maintains a blog, I would like to invite you to take my survey. The purpose of the following paragraphs is to give you the information you will need to help you decide whether or not to participate in the survey. Please read this information carefully.

Purpose:
To see how Iranians in the diaspora are using their blogs and specifically if they are promoting democratic values on their blogs.

Procedure:
My survey asks a few demographic questions regarding age, gender, and education level. In addition, my survey also will ask for your opinion about democracy and whether you think blogs can be used to promote democracy in Iran. The survey is short and will only take 15-20 minutes to complete. You are also free to skip any question on my survey that you don’t want to answer.

This survey is anonymous. Thus, your responses are not linked to your name. In addition, the survey answers will be confidential and will not be seen by anyone else.

Expected Benefits:
To understand if and/or how Iranians in the diaspora are using blogs to communicate with Iranians inside Iran. I also hope to discover if Iranians are using their blogs to promote democratic changes in Iran. If you would like to see the results of the survey at the conclusion of my study, feel free to contact me and I will email them to you.

Sincerely,
Arman Nafisi-Movaghar
