Why are titanium glasses so expensive?

Comfortable to Wear. Pure titanium frame can get rid of the stiff, heavy, easy-to-deform shortcomings of the common glasses frame, closely with the color plating process, indicating youthful vitality and a three-dimensional sense.

What Is Plastic Lens?

In the above part, we have introduced what polycarbonate lenses are. In this section, we will show you what the plastic lens is.

The plastic lens was first introduced in 1947. Since then, plastic has become a popular and widely used material for making eyeglasses lenses. Since the introduction and use of plastic lenses, it has sealed its mark as the most preferred choice in the optical industry.

Plastic lenses are light. With this feature, plastic lenses are popular because they will not be heavy inside the glasses frame and permit for an easy fit in any type of glasses frame. In addition, plastic glasses are cheap and easy to obtain in desired amounts. So, they are affordable for most people. Plastic lenses are very durable. So, they do not shatter easily on impact which makes it a great choice for individuals who are active or tend to drop their glasses often.

However, compared with other lens materials, plastic lenses are usually thick due to their low index of refraction. The soft feature of plastic glasses makes them susceptible to scratching from a sharp object and why scratch-resistant coating is applied to form an additional protective layer. Plastic lenses do not provide ultraviolet protection.



What Are the Disadvantages of High-Index Lenses?

This section will show high index lenses disadvantages.

  1. High index lenses are made from a chemical synthetic blend that’s created through a special manufacturing process. So, high index lenses are expensive than regular lenses. In fact, the price may be more than double that of the traditional counterparts.
  2. High index lenses can be more brittle than their traditional counterparts and may also be more prone to scrapes and scratches. This can impact their overall durability.
  3. High index lenses are more reflective than regular lenses, which can make them less effective for brightly lit work environments, outdoor use and nighttime driving on busy highways.
  4. High index lenses have greater potential for distortion, particularly in your peripheral vision because the high index lenses have a higher Abbe value than prescriptions made from standard plastic or glass.


Promises and Warranties of Optical Stores

They have a quality guarantee. Under normal use, the glasses will be replaced with the same value free of charge within six months if there is any quality problem attributable to the product itself. If there is any incompatibility within one month, the lenses will be re-checked and replaced with the same quality lenses free of charge. If you are not satisfied with the style of the frame, you can replace the frame of the same value free of charge within one week.



Adjust the nose pad

The height of the nose pad is adjusted by first holding the glasses with one hand and holding the nose pad with pliers with the other. Then the pliers are lifted up and the nose pad is moved down until the glasses are in the correct position on the face. The asymmetrical adjustment method is to first hold the frame of the eyeglasses with one hand, the other hand clamps the nasal plate with pliers. Then twist it in the direction of the correct tray position so that the surface of the tray is in contact with the two sides of the nose. Wrap one side of the lens of the glasses to be operated with a cloth first to prevent the screwdriver from slipping and scraping the lens during the operation. Don't scratch your glasses by adjusting your nose pad.


Wearing glasses correctly will not get deeper degrees

The development of myopia is not directly related to wearing glasses. Patients with myopia wear suitable glasses and pay attention to eye hygiene, and the degree of myopia will stabilize at a certain level. But if you think that with glasses, everything will be fine. If you don't pay attention to eye hygiene in normal times, if you continue to keep your eyes in a state of fatigue for a long time, it will lead to vision loss and deepening of myopia. In addition, wearing improper glasses such as no optometry or inaccurate optometry, too large power, will increase the burden on the eyes, reduce vision and deepen the power. For some people with high myopia (more than 600 degrees), although they insist on wearing glasses, the degree will still deepen, accompanied by changes in the fundus, which is medically called pathological myopia. This deepening of myopia is related to the degree of myopia and family and has nothing to do with wearing glasses.



Each type of store has its own characteristics.

Nowadays, the optical stores in the market can be roughly divided into professional optometry and optical matching stores, fast fashion stores, brand flagship stores, and stores in shopping malls. The benefits of fast fashion optical stores are fast commodity update frequency, and they follow the fashion trend, which can bring consumers quite more choices. The size of fast fashion optical stores is usually not large, so they will use an open showcase design. The color collocation should be able to catch the attention of consumers, to attract customers to make self-service selection and experience.
