Choose a frame for your face
People with round faces should try to avoid round frames, which can make your face look fatter. You can choose a square frame, having a decorated effect, and can make a person look more energetic. Circular lenses are recommended for square faces. Rectangular faces are also suitable for circular lenses. There are not too many restrictions on the choice of lenses for heart-shaped faces. Circular or square pieces are very appropriate, but you can choose slightly larger frames to add momentum and can create a retro sense.
Single Vision vs Progressive: What Are Their Differences
In this part, we will show you some differences between single vision and progressive lenses. They differ in several factors, so here we will compare them one by one.
Progressive lenses generally have their reading zones just in the lower half of the lenses, while single vision glasses have the reading power all over the lens. So if you are working on something above your head and you need to see some small details, the progressive lenses will not work. And you can not see through the reading zone in progressive you need to switch to single vision reading glasses.
Single vision glasses are cheap than progressive lenses. Compared to progressive glasses, single vision glasses hold way fewer distortions in the periphery. So, there is no need to customize the lens design to the max. In addition, single vision glasses are often available in the optical store while the progressive often needs to be produced for you. In other words, the delivery time of single vision lenses will be shorter for you.
You can use your progressive glasses optimally just in an upright posture. As soon as you lay down on your couch, this will lead to blurry vision. The reason is your changed position which forces you to look lower through the lenses on the screen. However, with single vision glasses, you can change to an upright position and it would not be a problem anymore. You can position yourself on your couch as comfortably as you want and you can still see clearly with your single vision distance glasses.
BLUPOND night driving glasses
TAC Semi-polarized Blue light goggles are designed to change your perspective to yellow with computer blue light polarization. Anti-glare high-definition vision blue-blocking glasses protect eyes from blue light and reduce the contrast of bright blue/white glare and flash. The anti-glare night glasses limit distortion. In addition to polarized driving glasses, you can receive a night vision glasses accessory set, with the EVA glasses hard case, screwdriver, sunglasses bag, microfiber cleaning cloth, glasses clip, and night driving glasses gift box.
The function of eyeglasses cloth
Under a powerful microscope, the fibers of the cloth are more closely arranged than those of ordinary cloth, and the material itself is softer than ordinary cloth. That's because eyeglasses under the eye are almost always coated, with each standard lens having seven layers of different functions on the front and back surfaces, to extend lens life. It can thoroughly remove the stubborn stains left on the lens to make the picture clear. It can clean all kinds of glass, resin, and other materials of glasses, glass mirrors, and other mirror surfaces, remove stains, and grease absorption.
Why do spectacle frames rust?
Before solving this problem, we can first understand the causes of rust spots on the frames and skin allergies due to rust spots. Many alloy products in daily life contain nickel, and direct contact with the skin will cause allergies to sensitive people. The temples and nose pads are the parts that contact the skin with a large area, especially the outer surface of the metal frame and the interior of metal containing a large amount of nickel. Through contact with the skin and erosion of sweat, the appearance of rust spots and skin allergies are caused. Once allergy occurs, it will cause contact dermatitides such as redness, swelling, itching, and yellow water on the surrounding skin.
Why do you need to wear safety goggles correctly?
Eye strain occurs when muscles are tired from strenuous exercise (from tension to concentration), similar to what happens to other muscles in the body from strenuous exercise or overuse. Eyestrain is the result of eye pain and fatigue, often accompanied by headaches. Eye strain has a lot to do with the quality of your glasses. If you wear cheap and inferior safety glasses for hours at work, you will feel uncomfortable. While your eyes won't be permanently damaged by fatigue, it can affect your productivity.
The advantages are not the same.
The cellulose acetate frame is acetate plastic, belonging to a kind of thermoplastic material, and it is a material for nearly 20 years. It is widely used in the glasses industry material. Now with the progress of processing technology, it can be divided into plate and injection molding. The acrylic frame of the propionic acid fiber belongs to a kind of thermoplastic material. The appearance is transparent. The main feature is that the material density is high. They are hard to burn and are not easy to change color, with Impact resistance. It has softness, dimensional stability, and good processing formability. Many high-grade plate glasses are based on these high-quality plates, so the quality is more reliable. It is designed for a large number of people and the pursuit of quality of life students, especially for women.
