Many sources claim that the word glasses probably derives from the word spyglass, an early word for the telescope and that it then probably adapted to " a pair of eyeglasses" when two lenses were joined together and held up to the eyes for full effect.

In general, the first glasses were used exclusively as visual aids to enable far-sighted individuals to read. Later, the first eyeglass frame temples were made by Spanish craftsmen in 1600s. They affixed ribbons of silk or strings to the frame and looped them over the user's ears.

The oldest specs ever found were discovered in a Chinese tomb, and are believed to have been worn by the owner of the tomb. Carbon dating suggests that these glasses were made sometime around 700 BC, with the lenses being made from polished quartz and the frames being crafted from bronze.

Because the first glasses were reading glasses. It was over 800 years ago, and back then only the wealthy/powerful were educated or able to read. Because they were the ones that had access to information, they were also seen as more intelligent.

A sure sign your prescription is wrong is if you can't see clearly through them. New lenses or a change in prescription can require a few weeks to adjust to, but if you're still struggling, there may be an issue. Besides blurry vision, watch for other signs of an incorrect prescription: Eyestrain.

Participants then estimated the age of the faces, displayed in random order. Contrary to the generally accepted beliefs that wearing eyeglasses makes you look older and wearing sunglasses make you look younger, our results suggest that the effect of glasses on age perception is rather small.

Choose larger frames that extend beyond your face for a mature and polished look. Avoid small frames or overly-trendy frames as they can often make you appear younger than you are. If only minimal coverage is desired, then opt for rounded frames with soft lines for a more mature feel.

Their study showed that both types of glasses elicited positive perceptions of those wearing glasses in terms of intelligence. Those who wear glasses also hold this stereotype, as they feel more intelligent and capable when they are wearing them (Harris, 1991).

One of the chief stereotypes about wearing glasses is a sign that a person is intelligent and well-read. Admit it: If you see someone wearing glasses, you think that person has a better chance than not of having an above-average IQ.

Errors can happen during an eye exam; an optician may read the optometrist's handwritten prescription wrong, or someone may make a typo when entering information into the computer. These errors can happen, but your optometrist can fit you with new glasses that offer clear vision.

When unneeded light reflects off the lens surface and mirror frame, ghosting occurs. Additionally, the lens' spherical front surface causes some degree of image distortion and contains aberration that cause problems such as color bleeding.

Warm-coloured tones such as berry, brown, jewel, and burgundies are good choices for older men and women. While black is versatile and can work for all ages, it can give a dull look. However, if you prefer a black frame, try a boxy or thick black frame for a more youthful look.
