Different Types of Progressive Lenses

The ground-view progressive lenses are designed for people who enjoy the outdoors. These lenses are supposed to provide a natural feel to your vision and reduce lens distortion. Ground-view progressive lenses allow better vision through the sides and bottom of the lens, so they give you improved vision when driving, using computers and looking downwards.

The standard progressive lenses are exactly what they sound like. They offer a wide reading area and have a longer drop between prescriptions and require a larger frame. However, they are less specialized than other lenses.


Titanium is currently too expensive to refine.

It is highly demanding in buckling, stamping, cutting, and welding. The extraction of titanium, like that of aluminum before the 19th century, was quite costly and produced in limited quantities, so it was used only in extremely important fields, such as aerospace, electronics, precision instrument manufacturing, and so on.



Is blue light blocking worth it?

There are two main problems with anti-blue glasses currently on the market. One is that the place to be prevented is not preventable, and the other is that people have color casts due to wrong protection and aggravate visual fatigue. Studies have shown that our eyes are the most intolerant of blue light in the 400-440 nanometer band. Therefore, current manufacturers mainly block blue light in this band when producing anti-blue glasses. However, the blue waveband of electronic products is between 450 nanometers and 490 nanometers, so most anti-blue glasses have little protection in this waveband. In addition, the blocking rate of anti-blue glasses is 20%~30% to achieve a good anti-blue light effect, but now the blocking rate of anti-blue glasses on the market has basically reached 80%~90%. All in all, these blocking blue light glasses cannot prevent the blue light in the 450-490 nanometer band, and their high blocking rate will also cause a color shift, which makes people more likely to have eye fatigue and headache.

In daily life, the intensity of blue light is low, not enough to cause damage to the fundus, so ordinary people do not need to wear anti-blue glasses unless they are working in extremely strong light conditions or working in special environments. To protect the eyes, it is more important for people to develop good eye habits. For example, wear a pair of suitable glasses and read insufficient light and at an appropriate distance. Avoid using electronic products for a long time. Take a break for 20 to 30 seconds every 20 to 30 minutes, and look at the distance regularly. If you have dry eyes while reading the electronic screen, remember to blink to 12 times per minute. It is best to wear sunglasses when outdoors.


Different Types of Progressive Lenses

The first progressive lenses we want to introduce are computer progressive lenses, which are designed for clear vision in office settings. These lenses are ideal when using a computer for over 4 hours a day and help to reduce eye strain.

Computer progressive lenses are intended for indoor use and should not be worn over your regular glasses. The drawback to this is it requires you to have two separate pairs of eyeglasses.

How to Wear Cat Eye Glasses?

Since the cat eye frame glasses are so popular, you may ask whether I can wear the cat eye glasses. Usually, cat eye glasses can suit a variety of face shapes. But faces with more angular or prominent features would look best in a round or oval shaped pair of cat eye glasses because these cat eye frame glasses will balance wide jawlines of square or triangle faces, while the rounded lens will soften sharp features.

However, the round face will look best in frames which are with bold and angular lines. These striking details will help to sharpen soft facial features and rounded jawlines. You can click here to know more knowledge of the face shape and how to choose the glasses frames.
