When were the first glasses invented?
No one knows when the first pair of glasses were invented, but we do know that the grinding techniques for making simple magnifying glasses have been around since 1000 AD, especially in regions where glasses were already produced (including northern Italy). The earliest artwork of glasses appears in the Treviso Cathedral fresco painted by Tommaso de Modena in 1352. There is reliable evidence that eyeglasses were invented in Italy in the late 13th century. The first pair we think of as eyeglasses appeared in Italian pizza in the late 12th century and looked more like two small magnifying glasses (made of raised glass) riveted together at the top of the handle. In 1266, The English Franciscan Monk Roger Bacon wrote about the scientific principles of corrective lenses, but there is no evidence that he applied this knowledge to the manufacture of eyeglasses.
How to Combat the Photophobia?
Photophobia can’t be completely prevented, but it can be managed. So, you can try the following suggestions.
- Wear photophobia glasses, computer glasses, or glasses for light sensitivity.
- Choose natural lighting for indoor settings when possible.
- Consider vision therapy.
- Wear blue light blocking glasses.
- Seek medical attention if symptoms worsen.
So, from the above information, you can find that you can wear photophobia glasses to relieve the photophobia. What are the benefits of photophobia glasses.
What is blue light?
Our daily lives are inseparable from mobile phones, computers, tablet computers, and other electronic products. Many people's eyesight is also going downhill due to long-term exposure to strong light electronic screens, and their eyes are more or less potentially adversely affected. It is found that many optical stores sell blue light filter glasses, which have the function of blocking 99.9% UV and scattered blue light, alleviating visual fatigue. They claim that these glasses can block short-wave blue light emitted by electronic products such as mobile phones and computers, and even prevent age-related macular degeneration so they are much sought after by consumers. The price of these so-called anti-blue-light glasses varies greatly, ranging from dozens of dollars to several thousand dollars. Do these blue light blocking glasses really have so many magical functions?
The natural light seen by the human eye is composed of a spectrum of different colors, including red light, orange light, yellow light, green light, blue light, indigo light, purple light, which gives people a visual feeling of white. Different wavelengths present different colors visually, and the shorter the wavelength, the higher the energy. At present, products with electronic screens such as computers and mobile phones use LEDs and other materials to emit light mainly in three colors of red, green, and blue, and blue light accounts for the main part. Blue light belongs to the range of visible light, belongs to short waves. And the wavelength is between 400 nanometers and 500 nanometers, which is close to ultraviolet and carries a large amount of energy. And this part from 400 nanometers to 450 nanometers is called high-energy short-wave blue light.
Characteristics of Carbon Fiber Glasses
Carbon fiber frames have pretty impact resistance. Carbon fiber is made of carbon, the core element of diamonds. It is ten times stronger than iron, and it weighs less than steel. The maximum stress it can withstand before breaking is 7 to 9 times that of steel. Carbon fiber is more resistant to corrosion than metals like titanium. It has high-temperature resistance, radiation resistance, good elasticity. Carbon fiber is not only flexible, but durable, so it won't break if you drop it. Carbon fiber has many benefits, including high stiffness, high tensile strength, low weight, high chemical resistance, high-temperature resistance, and low thermal expansion.
Can I Help My Eyes Adjust New Glasses Quickly
To make your eyes adjust to the new glasses quickly, the best way is to wear them. As long as you are awake up, put on the new glasses and do not wear your old glasses.
How to adapt to progressive lenses?
People who are prone to motion sickness or have inner ear diseases may suffer dizziness, nausea, vomiting, and other symptoms due to their inability to tolerate the slight deformation of the visual objects, so they need to pay more attention when wearing them. For people who have not worn reading glasses before, it is not recommended to wear graded multi-focus glasses directly because their eyes will not be able to adapt quickly.
Glasses with metal frames.
This is a very popular style of glasses. The feature of the glasses is that they look classic and retro, but when worn with modern clothes, they will make people feel bright.
The first feeling given by metal frames is retro, indeed, no matter what kind of metal frame is worn, there is always a kind of old retro flavor. But metal frames aren't just retro for anymore. Now, the metal glasses frame is synonymous with the avant-garde.
