What Are the Advantages of High-Index Lenses?

In this section, we will show you the advantages of high-index lenses.

  1. Thanks to the slim shape and narrow edges, high index lenses offer wearers the flexibility to choose from a wide array of fashion-forward frames. Their size means that they can be easily paired with sleek metal frames or incorporated into rimless eyewear for an attractive barely-there look.
  2. High index lenses are more comfortable for extended use because they are lighter than the traditional counterparts.
  3. High index lenses are available with many of the same options as traditional lenses. For example, they can be either single-vision or progressive.
  4. For users with strong prescriptions, high index lenses mean no bulky, bottle-glasses appearance. This can reduce the unwanted bug-eye look traditionally associated with very thick lenses.

However, there are some negative voices of high index lenses.


Polygonal metal frame

The metallic frame that is full of contemporary and retro feeling still did not end curtain. Stylish people like to use it to match modeling nowadays.

Vintage oval frames

It's a pair of glasses with a retro, '90s-like frame feels that's very popular with hipsters. They are retro with a little cool cute.

The cat-eye style

The cat-eye style can be seen in the changing history of eyewear trends as far back as the 1940s. Flying nifty cat-eye has been unable to show the stage. But times have changed, and the styles of cat-eye have become more varied. Some brands provide multiple types of cat-eye glasses, showing different atmospheres and domineering.



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.


Protect the lenses of your safety glasses.

Scratches can be caused by damage at work, aging, improper care, improper cleaning, or improper storage. Whatever the cause of a scratched lens can affect vision quality through the polycarbonate, causing eye strain. Make sure the safety glasses lenses are replaced in time when they are scratched.



What Do Pinhole Glasses Do?

Pinhole glasses are often used by eye doctors who use them as a diagnostic tool to quickly check for vision impairments. Of course, pinhole glasses are sometimes used to treat nearsightedness or astigmatism. Pinhole glasses are also used in conjunction with an occluder, an instrument used to cover one of your eyes while you read an eye chart. The occluder is solid, while the pinhole glasses have a number of tiny pinholes. So, the doctor often uses it to check the potential of your vision.

Pinhole glasses are often used to check corneal distortion and cataracts. A cataract evaluation includes focusing light in the eye to check if vision capability behind the cataract makes it worth performing surgery.


Why are eyeglass frames are so expensive?

The industrial chain has factories, brand owners, regional general agents, retailers. Each link needs to share the risk and profit. They have high operating costs. In addition to the well-known rent, they have the costs of labor, decoration, and so on. There is another important reason. It is the inventory loss because of the style problems. This aspect of the cost must be amortized. From the structure and appearance design of the glasses frame, the development and application of raw materials, processing technology, to manufacturing equipment and procedures, the actual cost may be much higher.



What Are Varifocal Glasses?

Varifocal glasses, also known as varifocals, varifocal lenses, PALs, or progressive lenses, have a gradual change in strength from the top of the lens to the bottom with multiple focal points in between. This allows you to see all distances and focus points through just one lens. Varifocal lenses are typically used when you have two prescriptions, one for distance and one for reading.

There are three regions of a varifocal lens which are distant zone, intermediate zone and, near/reading zone. Usually, the upper portion of the varifocal lens is the distant zone and the bottom portion of the varifocal lens is the near or reading zone.

One of the benefits of varifocal glasses is that you do not need to prepare 2 separate pairs of glasses or need to switch between frames for different vision needs.
