How Do You Get Rid Of Computer Vision Syndrome?

Does it take time to adjust to progressive lenses?

How long should it take to get used to progressive lenses? I have never worn glasses before.Progressive lenses were developed to allow easy switching between near and far views. Progressive glasses are divided into four parts. The upper part is the far-light region. The lower part is the near-light region, and the middle part is a variable light region. From top to bottom, if the hyperopia film is gradually increased and the myopia film is gradually decreased. The middle variable area is on both sides of the astigmatism area. Because of the prism effect, when you see things, through this area, the object will be blurred, and the eyes will feel uncomfortable. If the height of the frame itself is very small, the transition zone of progressive multi-focus is very narrow, and the eyes may not adapt to the sunglasses. The current design of progressive lenses is still not mature. Imported brands are relatively stable but expensive, and domestic brands are not mature in design. For various reasons, progressive glasses may be difficult to adapt to wearing.


If you need reading glasses when using a computer, you may want to choose a lower reading glasses power. This is because most people view their screen from a greater distance from their eyes than when they are reading a book or a magazine.

However, if you need reading glasses for looking at something very close or very small, you may need a pair of stronger power glasses.

In most cases, when two reading glasses’ powers seem equally suitable, choose the glasses with the lower power. Picking reading glasses that are too string typically will cause more discomfort problems than reading glasses that are a little too weak.



Do Colorblind Glasses Work?

To understand colorblind glasses well, you need to know how color blindness happens first. The human eye contains three photopigments that are sensitive to color. These photopigments are located inside receptors in the retina called cones, which can tell your eyes how much blue, red or green is in an object. Then they give your brain information about what color objects are.

If there is not enough photopigment in your eyes, you maybe can’t see that color. Most cases of poor color vision involve red-green color deficiency. That is to say, you have the difficulty in recognizing the red and green colors.

So, how do colorblind glasses work? Colorblind glasses like Enchroma were originally manufactured as sunglasses with lens coated in a special material that exaggerated the wavelengths of light. So, it has the effect of making colors look saturated and rich.

Though colorblind glasses do not cure color blindness or produce 100% normal color vision, they allow colorblind people to perceive colors they have never seen before and experience closer-to-normal color vision while wearing special glasses for color blindness.


Do not wear blue light blocking glasses for a long time.

Blue light from the screen of electronic products directly enters our eyes. It has high energy and is close to our eyes, so it is more harmful to our eyes. This is why we should prevent electronic products. From the original intention of the blue light glasses, blue light glasses are for us to wear when using electronic products, not all day long. Therefore, if your child is not using electronic devices, it is recommended not to wear blue light glasses.



Other problems with titanium frames

For the same volume of frames, alloy frames are twice as likely to break as pure titanium frames, and for the same weight, alloy frames break more easily than pure titanium frames.Therefore, some sellers have to add a lot of copper in alloy material and impure titanium material to increase the toughness of the frame, so that the alloy frame is easy to rust, and long-term wear will be eroded because of the salt in sweat.


Disadvantages of Progressive Lens

There are deformation areas under the left and right sides of the lens, which make the image blurry and irregular. It takes 1-3 weeks to get used to it. In addition, it has a narrower field of view in the near and middle distances, and long-term concentration on the narrow focal point can easily make the eyes tired. Suitable for people who need to alternate between distant, medium, and near vision.

However, with the development of science and technology, more and more progressive multifocal glasses have emerged that have a wider field of view, more comfortable wearing, and better meet the needs of eyes. Nowadays, the use rate of progressive lenses among middle-aged and elderly people abroad is quite high. Single-lens and double-lens reading glasses are gradually being replaced by progressive multifocal glasses.
