Benefits of glasses
You don't need a special cleaning plan, and they don't require much care. You can choose from a variety of frames to suit your style. If your vision stays the same, you won't need to change your glasses as often. You don't need to touch your eyes to wear them, and in addition, glasses can adjust the amount of light entering your eyes for optimal comfort and vision. Glasses are more powerful modifiers than contact lenses. Glasses are not only used as a tool to correct vision but as accessories. On different occasions, the different dresses should match different frame glasses, reflecting the person's different temperament.
The nose pad
When you're shopping for a driver's glasses, you can't ignore a nose pad. Choose one that is soft and elastic. This way, it won't make your noses feel depressed or uncomfortable.
An oval face fits all frames.
It is still expensive to get glasses, so it is best to know what shape you are suitable for before getting glasses. A suitable pair of glasses frame, not only can make the vision more clear but can increase the appearance. There are different tips and methods for choosing glasses for different face types. Glasses can not only assist myopia, but play the role of modifying the face, so how should different face types choose suitable glasses?
If you have an oval face, you should be lucky to have a uniform shape that allows you to pull off all frames. The widest part of this face is located in the front part and moves smoothly to the forehead and the sides of the chin. Due to uniform proportion, the face has no special defect to cover.
What Is Bifocal Lens?
Changes in vision seem to be related to age. Presbyopia, a common eye condition that occurs in middle age, causes changes in your eye’s ability to focus. But this condition can be corrected by wearing bifocal glasses.
Bifocal lenses are divided into two parts to accommodate two different prescriptions in one lens. One area of the lens will have one prescription (usually distance) and a segment in the lower half will have the other (usually near vision).
The bifocal glasses were invented by Benjamin Franklin, who solved his own vision problem by taking the lens from his reading glasses and distance glasses and cutting them in half. Then remade the cut lenses into a single pair of bifocals and put the distance lens on top and the reading lens on the bottom.
Adjustment of the upper and lower position of the nose pad
The nose pad can be pulled up and down with the pliers of the nose pad to achieve the purpose. You can use needle-nose pliers to clamp on the nose pad and apply torque in a certain direction to change the upper and lower position of the nose pad. When applying the torque, the nose pad can be pressed down or pulled up by the pliers to change the position of the deformation of the bracket, to prevent repeated deformation and fracture near the solder joint.
Acetate frame and plastic frame
What is the difference between acetate frame and a plastic frame? Acetate frames are lighter and generally considered to be better than plastic frames. Acetate is known for its hypoallergenicity, so it is a popular choice for people with sensitive skin. Unlike some plastic or metal frames, they can cause allergic reactions.
- The manufacturing process makes the plastic frame more brittle than the acetate frame.
- If the temple does not have a metal bracket, it is difficult to adjust the plastic glasses.
- There are fewer choices of colors and patterns for plastic frame
However, you will notice that acetate frames are generally more expensive than ordinary plastic frames. Spectacle frames are daily necessities that we use for a long time. Therefore, durability is essential, and the life span of the acetate frame is longer.
Choose the frame according to the hairstyle
If there are bangs, the upper edge of the frame should avoid contact with hair. If it is curly hair, it should be noted that the frame should not be too large so that the frame edge contacts the hair.
