There are some people who just wouldn’t be ‘themselves’ without their glasses. But did you ever wonder why they wear glasses?
Can you imagine John Lennon without his granny-style glasses? They became a trademark look for this musician.
While he was getting for his role in the film, How I Won the War, Lennon was given these glasses to wear. Apparently, the look worked for him and he kept them. Optically speaking, he was very nearsighted and wore glasses since he was seven.
Susan B. Anthony
This civil right leader is best known for championing women’s right to vote. Politically, she had a vision but her optical vision was also well known. She wore glasses to cover up her ‘lazy eye.’ This condition began in childhood and was characterized by reduced vision in one eye caused by abnormal visual development. The glasses she wore as an adult were meant to disguise this condition.
If treatment is started in early childhood, ‘lazy eye’ can be most often successfully cured.
He is credited with inventing bifocals because he was tired of switching from his two pairs of glasses. Franklin’s idea was the perfect solution: he cut the lens of each pair horizontally. The reading glasses were on the lower part of the glasses, while distance vision was addressed through the upper half.
Today, bifocals are a bit more sophisticated but the basic concept is the same. One lens with more than one use has proven to be very convenient for a large number of people, especially those over the age of 40. Presbyopia is an age-related condition in which the lens of the eye hardens and makes it difficult to focus on objects that are close. Corrective eyeglasses, including bifocals, can significantly improve vision.
His gold aviator glasses immediately come to mind and they may have been used to address a condition he acquired later in life: glaucoma. In the late 1960s he developed this eye condition which caused pain when he was in sunlight or in front of a spotlight.
Glaucoma damages the eye’s optic nerve, and if not treated will get worse over time, eventually leading to permanent vision loss. This condition can be diagnosed with regular vision and eye exams and can often be successfully treated in the early stages. While Elvis’ famous glasses might have given him a measure of relief, they couldn’t stop the progression of this disease.
All of these famous people had one thing in common: their vision needed correction. Whether it was nearsightedness, a lazy eye, or glaucoma, the eyes of all of these people either were helped or could have been helped with a vision exam. We remember these celebrities and history makers through the lens of time. We also keep an image of them in our minds with their glasses on. Knowing why they wore glasses may keep our memory of them to be a little clearer.
Wearing corrective eyeglasses can be more than a fashion statement; it can tell everyone that you are serious enough about your sight to get it checked regularly.

Do Sunglasses Make You More Attractive While Protecting Your Eyes?
Your Amazing Eyes and How to Keep Them Amazing
Red Eyes and Selfies: Not a Good Look
by Joyce Handzo
Sunglasses are way more than just an accessory. Did you know they shield your eyes from sun damage while they make you more attractive?
Now that you’re paying attention, read on to see how (and why you should wear sunglasses anyway).
Looking Cool is not the Only Benefit
The whole reason we even need a pair of sunglasses is due to the existence of ultraviolet radiation. You probably know this as “UV rays.” The sun itself, not just the light, is our main exposure to these. What this means is that your eyes are picking up UV rays even on cloudy days.
UVA, UVB, and UVC rays combine to make what we consider UV rays. You need sunglasses for the first two. Cataracts and photokeratitis (sunburn on your cornea) are two serious eye problems directly related to UVB exposure. This alone should be enough to make you put sunglasses on but there are also UVA rays to worry about. These are linked to retina damage, causing loss of central vision. Whereas UVB rays are largely absorbed by your lens and cornea, UVA rays actually get inside your eye. Don’t forget, UVB rays are still considered the most dangerous.
What to Look for
Good thing you don’t have to choose which one to protect yourself from. There are a few things to look out for when picking out a pair of sunglasses. The first and most important is that they should block 99 to 100 percent of both UVA and UVB rays.
They should also screen 75 to 90 percent of visible light (which is different than protecting from UV rays). The lenses should seem identical, in both color and in lacking imperfections.
Darker does not Equal More Protection
The color of the lens has nothing to do with how much UV protection lenses provide. In fact, early versions of sunglasses were dark but blocked no UV rays.
Reducing the light while looking at something is why the very first pair of sunglasses was invented. At around the 12th century in China, smoked quartz “lenses” were held up to the eyes to block some of the bright sun. Although they didn’t block UV rays, they did hide the wearer’s emotions. Might this last reason be why they were popular with both the very rich and judges in court?
Sunglasses Make You More Attractive
Here’s the part you were waiting for. Celebrities aren’t just using oversized sunglasses or reflective aviators to hide from the paparazzi. There are two reasons explaining why we are better looking with sunglasses on.
They fix our facial symmetry. When you have on a pair of big sunglasses which protects not only your eyes, but half your face from the sun, you also hide any facial asymmetry. Science has linked facial symmetry with how attractive we perceive someone to be. As we tend to look at people’s eyes, we notice asymmetry there first. Sunglasses cover these up, making us appear more symmetrical, and more attractive.
The second has to do with those Chinese judges. They hide our eyes which reveal our emotions, giving us an air of mystery. This draws people in because they want to solve the “puzzle” of our emotions. (The judges used them to discuss issues in court without their emotions betraying their true feelings, allowing them to appear impartial.)
