Glasses, also known as eyeglasses or spectacles, are vision eye wear, with lenses (clear or tinted) mounted in a frame that holds them in front of a person's eyes, typically utilizing a bridge over the nose and hinged arms (known as temples or temple pieces) that rest over the ears.
Glasses are typically used for vision correction, such as with reading glasses and glasses used for nearsightedness; however, without the specialized lenses, they are sometimes used for cosmetic purposes.
Safety glasses provide eye protection against flying debris for construction workers or lab technicians; these glasses may have protection for the sides of the eyes as well as in the lenses. Some types of safety glasses are used to protect against visible and near-visible light or radiation. Glasses are worn for eye protection in some sports, such as squash.
Glasses wearers may use a strap to prevent the glasses from falling off. Wearers of glasses that are used only part of the time may have the glasses attached to a cord that goes around their neck, to prevent the loss of the glasses and breaking. The loss of glasses would be detrimental to those working in these conditions.
Sunglasses allow for better vision in bright daylight, and may protect one's eyes against damage from excessive levels of ultraviolet light. Typical sunglasses lenses are tinted for protection against bright light or polarized to remove glare; photochromic glasses are blacked out or lightly tinted in dark or indoor conditions, but turn into sunglasses when they come in contact with ultraviolet light. Most over-the-counter sunglasses do not have corrective power in the lenses; however, special prescription sunglasses can be made. People with conditions that have photophobia as a primary symptom (like certain migraine disorders or Irlen syndrome) often wear sunglasses or precision tinted glasses, even indoors and at night.
Specialized glasses may be used for viewing specific visual information, for example 3D glasses for 3D films (stereoscopy). Sometimes glasses are worn purely for fashion or aesthetic purposes. Even with glasses used for vision correction, a wide range of fashions are available, using plastic, metal, wire, and other materials for frames.
Scattered evidence exists for use of visual aid devices in Greek and Roman times, most prominently the use of an emerald by Emperor Nero as mentioned by Pliny the Elder.
The use of a convex lens to form an enlarged/magnified image was most likely described in Ptolemy's Optics (which survives only in a poor Arabic translation). Ptolemy's description of lenses was commented upon and improved by Ibn Sahl (10th century) and most notably by Alhazen (Book of Optics, c. 1021). Latin translations of Ptolemy's Optics and of Alhazen became available in Europe in the 12th century, coinciding with the development of "reading stones".
Robert Grosseteste's treatise De iride (On the Rainbow), written between 1220 and 1235, mentions using optics to "read the smallest letters at incredible distances". A few years later in 1262, Roger Bacon is also known to have written on the magnifying properties of lenses. The development of the first eyeglasses took place in northern Italy in the second half of the 13th century.
Independently of the development of optical lenses, some cultures developed "sunglasses" for eye protection, without any corrective properties. For example, flat panes of smoky quartz were used in 12th-century China, and the Inuit have used snow goggles for eye protection.
The earliest recorded comment on the use of lenses for optical purposes was made in 1268 by Roger Bacon.
The first eyeglasses were estimated to have been made in central Italy, most likely in Pisa, by about 1290: In a sermon delivered on 23 February 1306, the Dominican friar Giordano da Pisa ( c. 1255–1311) wrote "It is not yet twenty years since there was found the art of making eyeglasses, which make for good vision ... And it is so short a time that this new art, never before extant, was discovered. ... I saw the one who first discovered and practiced it, and I talked to him."

Each year around this time, friends and families begin mailing their holiday cards. Christmas Card Day on December 9th serves as a reminder to get your stamps, envelopes, and cards together so you can share your holiday cheer.
Sending a card during the holidays hasn’t always been a tradition. In Victorian England, sending Penny Post was inexpensive and frequent. It was also considered rude to ignore a written message. One particularly popular Victorian invented the holiday card out of necessity. Sir Henry Cole received frequent letters, and it left him little time for other responsibilities. In 1843, he asked his friend J.C. Horsley to illustrate a design he had in mind. Soon, Cole was off to the printer, and he mailed the first Christmas card in the Penny Post to friends, family, and many acquaintances.
Today, we mail a variety of cards at Christmastime. The tradition of Christmas cards continues in a broader sense. Social and electronic media keep us connected in this modern world more than ever before. However, the Christmas card continues to be a part of our annual tradition, even if it takes on a different style or pattern.
- Photo cards – Many families take an annual holiday photo specifically for mailing to friends and family. These photos may be snapshots or professional photos. Most families save them from social media, so they remain a surprise when they arrive in the mail, too.
- Christmas letter – These letters often highlight the events for each family member for the year. Not everyone has social media, so it’s a nice way to catch up with friends and family. The letters usually run a page in length, but some letter writers have a lot more to say.
- Postcards – These simple cards generally send the same holiday message a regular Christmas card does, but without a fold or an envelope. With a photo on one side and a simple message on the other, they are quick and easy to send, too.
- Business card – Christmas cards also come from businesses who want to remind us they still want our business. As a marketing tool, businesses know their best customers like to be remembered during the holidays, too.
- New Year’s cards – The holidays do get busy, and some of us put off sending any holiday cards until New Year. They still want to keep in touch with family and friends, so they send their good wishes in the form of a Happy New Year card. So, don’t mark anyone off your Christmas card list until after the first of the year.
These holiday cards may be the only communication we receive all year long from a friend or family member. Even if we spent an abundance of time with them once, these once-a-year notes touch us with a bit of meaning this time of year. We take the time to connect once again and say, “We’re thinking of you.”

CHRISTMAS CARD DAY HISTORY
While the origins of Christmas Card Day continue to be researched, Sir Henry Cole does receive credit for creating the first Christmas Card in 1843. However, the idea took several years to find its way to the United States. In 1850, Louis Prang immigrated from Prussia and opened a print shop in Boston. He mastered many methods of lithography from around the world, and after encouragement from his wife, he began producing floral Christmas cards in 1875.
