Do We Need Blue Light?

Why is it risky to get glasses online?

The safety and professionalism of online lens matching are widespread concerns of consumers. The whole process of online lens matching is networked, and only a prescription sheet for online lens shopping cannot provide comprehensive and detailed feedback on patients' eye conditions. Therefore, there will be many safety concerns about myopia, high myopia, and astigmatism when they choose to choose glasses online. They have to think about that if the products are qualified, if the quality is good if the style is consistent with the real thing, and so on.

Benefits of Progressive Lenses

The lens looks like a single vision lens, with no dividing line between degrees. Not only is it beautiful in appearance, but more importantly, it protects the privacy of the wearer's age (for the wearer of reading glasses). There is no need to worry about showing the secret of the wearer's age by wearing the glasses. Because the degree is gradual, the replacement of the adjustment effect is increased step by step according to the shortening of the close distance. There is no adjustment fluctuation, which is not easy to cause visual fatigue. Clear vision can be achieved at all distances in the visual scope.

Titanium alloys have low thermal elasticity

The thermal conductivity of titanium is about 1/4 of nickel, 1/5 of iron, 1/14 of aluminum, and the thermal conductivity of different titanium alloys is about 50% lower than that of titanium.

The elastic modulus of titanium alloy is about 1/2 that of steel, so its rigidity is poor and is easy to deform, and it is not suitable to make slender rods and thin wall parts. When cutting, the spring back of the processing surface is very large, about 2 ~ 3 times of stainless steel, resulting in severe friction, adhesion, and bonding wear of the knife surface.

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.
