How to Wear Cat Eye Glasses?
Since the cat eye frame glasses are so popular, you may ask whether I can wear the cat eye glasses. Usually, cat eye glasses can suit a variety of face shapes. But faces with more angular or prominent features would look best in a round or oval shaped pair of cat eye glasses because these cat eye frame glasses will balance wide jawlines of square or triangle faces, while the rounded lens will soften sharp features.
However, the round face will look best in frames which are with bold and angular lines. These striking details will help to sharpen soft facial features and rounded jawlines. You can click here to know more knowledge of the face shape and how to choose the glasses frames.
Disadvantages of contact lenses
They require more care than glasses. If you don't clean your contact lenses properly, or if you don't wash your hands before touching them, you could get a serious eye infection. Wearing contaminated contact lenses not only causes damage to your eyes but causes inflammation. If you have high astigmatism, your vision may become blurry when the lenses rotate. And there are a lot of contact lens health risks. There is a lot of news exposed that many informal manufacturers use fake or shoddy materials to make contact lenses, especially for the so-called beautiful contact lens, there are more risks in dyeing and health. The damage to the eyes is unimaginable.
Disadvantages of Progressive Lenses
It is limited in applicable range. Progressive multi-focus lenses have no limit in strength and can be worn for myopia, presbyopia, or moderate astigmatism, but they are not suitable for everyone. Now there are more than two categories of asymptotic focus lenses, one is hard and the other is soft. A person who can understand and adapt to the temporary discomfort that progressive multi-focus lenses begin to produce can have a pair of glasses. If you have severe symptoms such as high blood pressure, dizziness, or have a misunderstanding on progressive multiple focal lenses, and you are unwilling to adapt to them, it will be difficult to try.
What Is Photophobia?
There are a lot of reasons causing our eyes discomforts, such as moving between indoors and outdoors on bright sunny days, staring at computer screens all day, driving at night, or watching TV. If the discomfort worsens over time with accompanying symptoms such as intense pain, excessive squinting, excessive tearing or burning sensations, it may become an eye condition called photophobia or light sensitivity.
One of the symptoms of photophobia is intolerance of light. To some degree, most of us are sensitive to bright or fluorescent lights, but those suffering from photophobia may experience a range of symptoms - from minor or mild irritation to serious debilitating reactions. The symptoms can include dizziness, headaches, migraines, server eye pain, excessive blinking, blurriness, and eye inflammation.
So, they are a few ways to combat photophobia.
What Is Blue Light Glasses?
Blue light glasses are designed to absorb excess blue light from the many kinds of digital screens in our home and the office spaces. Blue light glasses is becoming more and more popular because it can protect the eyes from the invisible but harmful blue light projected by digital screens. With them, you can enjoy a life with less eye strain and a healthier sleep cycle.
With so many advantages, you may ask whether I can wear blue light glasses all the time. The following part shows some information.
The TR90 Spectacle Frame
TR90 frame is a kind of polymer material spectacle frame with memory, no chemical residue is released, and it meets European requirements for food-grade materials. It is currently an internationally popular ultra-light spectacle frame. TR90 frames have the characteristics of super toughness, impact resistance and abrasion resistance, and low friction coefficient, which can effectively prevent damage to the eyes and face caused by the breakage and friction of the frame during sports. Because of its specific molecular structure, it has good chemical resistance, is not easy to deform in high temperature environment, can withstand high temperature of 350 degrees in a short time, and is not easy to melt and burn. Moreover, the TR90 spectacle frame has a lubricating surface with a density of 1.14-1.15. It will float when placed in salt water. It is lighter than other plastic spectacle frames. It is about half the weight of the sheet frame and 85% of the nylon material. It can reduce the burden on the bridge of the nose and ears.
About Prism Glasses
The refractive index of the same medium is different for different colors of light. Different colors of light travel at different speeds in the same medium. Because the same medium has a different refractive index for various monochromatic light, and the deflection angle of each monochromatic light is different when passing through a prism. Therefore, white light through a prism will separate the monochromatic light, known as dispersion. What is the prism effect of glasses? As long as there is a deviation between the visual channel of the eye and the optical center of the lens, it can produce a prism effect. Therefore, the severity of the prism effect can be used to measure whether the glasses with the correct prescription are processed correctly and reshaped correctly.
