About Non-polarized Sunglasses
Non-polarized sunglasses block only commonly strong light and filter ultraviolet rays. And the efficiency of its filter ultraviolet ray is lower. But you know, in our daily life, in addition to strong light and ultraviolet light, the light through the uneven road surface, water, and other places will also produce an irregular diffuse reflection of light, so that the human eyes will suffer blurred vision, fatigue. Generally speaking, for a short period of outdoor sports, the non-polarized sunglasses can already meet your needs.
The clear frame is paired with wire glasses.
Compared to traditional chunky glasses, gold-rimmed glasses have less color saturation, so they are almost skin-neutral. Gold-rimmed glasses and clear frames are similar in style but more decorative. The geeky-chic style has become popular since the Gucci fashion show, which started with large frames. Who says you can't be stylish with glasses?

How to determine whether progressive lenses are worn correctly?
Once your glasses are back from the lab, the optometrist will let you put them on for an audition and make final adjustments to make sure they fit. If the prescription is not in the center of the lens, it will make it difficult for you to see clearly. The key is that the lenses match the wearer's eyes, especially the pupils. Before ordering a new lens, the optometrist takes two measurements: pupil distance and fitting height.
Heart-shaped face with angular glasses
The heart-shaped face is also a common face shape in daily life. This face shape is somewhat similar to the inverted triangle face shape. Generally, the chin is a relatively sharp face shape. For this type of face, the most important thing is to modify the cheekbones above the nose to highlight the slenderness of the chin. Therefore, it is better to wear a pair of angular glasses, which can effectively modify the facial lines and look more perfect.
Should I wear glasses all the time for myopia?
Whether it is false myopia or true myopia, as long as a pair of suitable myopia glasses are used to complement the missing refractive power of the lens, the image of the object can fall on the retina again, and the distant objects can be seen again. Adolescents usually use high eye intensity and often wear myopia glasses, so that the ciliary muscles do not need to be 'so tired' to adjust, which can avoid further aggravation of pseudomyopia. However, adolescents are still in the process of development, and the degree of true myopia will gradually increase with age. Therefore, as the degree of myopia develops, refraction should be performed at regular intervals, and appropriate glasses for myopia can be prepared to prevent false myopia.
For adults under 200 degrees, because the degree is relatively light, they can wear glasses when they are looking at the distance and not wear glasses when they are near, which has little effect on vision. But for adults with high myopia, because of the weak adjustment ability of the eyes, it is recommended to wear glasses regardless of near vision or distance vision.
In summary, wearing myopia glasses is to reduce eye fatigue and prevents the occurrence of false myopia. Wearing myopia glasses from time to time may aggravate the degree of myopia, and wearing them often does not cause a burden on the eyes. Therefore, for myopia glasses, wearing them frequently is the most correct way to wear them.
What Do Blue Light Glasses Do?
Blue light has wavelength and energy from 380 nm with the highest energy to 500 nm with the lowest energy. The violent and blue-violent rays are more likely to damage our eyes so these rays are also called harmful blue light.
The blue light can be from the sunlight, fluorescent light, LEDs, computer monitors, smartphones, and tablet screens. Long time exposure to blue light may cause eye strain and discomfort. Hence, wearing blue light glasses is an effective way to prevent your eyes from harmful blue light.
What do blue light glasses do? They are specially designed to filter out harmful blue-violent light rays that are commonly emitted from digital screens.
