How to Perform Glasses Measurements?

If there is no number on the temple of eyeglasses, you can perform glasses measurements by yourself. Now, we will show how to do that.

To measure the glasses’ size, you need to prepare a ruler or a tape first. To measure the frame width, measure the entire horizontal front of the frame, from the furthest extended point on either side. As for lens height, you should measure the vertical height of the lens. As for the bridge, you should measure the part that goes across the bridge of your nose. The temple arms include the front of the frame on either side and the rest behind your ear. The lens width is the horizontal diameter of one lens. So, when measuring these, you should be careful.

After that, you have measured the glasses frame size. If you want to know whether your face is right for this frame, you can read the post: How to Measure Face for Glasses Frames - 7 Steps

Are carbon fiber glasses good?

Carbon fiber glasses are continuously changed to meet consumer demand. Adhering to the use of carbon fiber, they are more in line with the requirements of environmental protection and health. In the design of the new carbon fiber products, the weight of the bridge of the nose is further reduced when wearing, making it more fit and comfortable. Should you choose carbon fiber glasses or titanium glasses? It depends on your preference, ?like style, color, material, price, and so on. Because they are very not heavy, carbon fiber glasses are the most comfortable option for everyday wearers who are looking for the latest technology and the highest quality.


What Are Bifocal Glasses?

Bifocal lenses are divided into two parts to accommodate two different prescriptions in one lens. One area of the lens will have one prescription (usually distance) and a segment in the lower half will have the other (usually near vision).

Bifocal glasses are most used to correct presbyopia - an age-related eye condition where the eyes begin to struggle to focus on anything up close. This difficulty usually results in people requiring glasses with two different prescriptions, one for short and one for long-distance.

On bifocal glasses, there is a distinct line between the different prescriptions. Wearers have to look up and down to switch between the prescriptions they need, with long-distance prescriptions at the top and near vision at the bottom.

How do anti-blue light glasses protect the eyes?

The anti-blue light glasses available on the market, no matter what type, etc., are mainly the difference in anti-blue light effect, light transmittance, and frame, which will affect the cost of glasses. Obviously, the lens is the most important of these. I think that it is basically enough to choose 30% to 40% anti-blue light glasses. It is good to cut off the harmful blue light. It is not necessary to completely eliminate the blue light so that the chromatic aberration will not be too large, the light transmittance is better, and it also has a certain anti-blue light effect.

Of course, to protect the eyes, it is not enough to rely on anti-blue glasses alone. The effect of anti-blue glasses is mainly to reduce the probability of eye diseases, and can not effectively relieve eye fatigue. Normal people between the ages of 20 and 40 blink about 20 times per minute. When you open your eyes and stare at a computer screen that changes rapidly, the number of blinks will be reduced to 4 or 5 times per minute, resulting in serious insufficient secretion of scum and dry eyes. Therefore, no matter how urgent the work is, you must pay attention to the rest of your eyes, close your eyes regularly, use eye drops when needed, and reduce the brightness of the screen as much as possible when looking at the screen. When the brightness of the screen is significantly higher than the ambient light It is easy to cause eye fatigue. Try to use it as little as possible in the dark. To be honest, it is more important to develop a good eye-using habit.

The superior properties of titanium glasses

They are light, around 40% of stainless steel. The hardness is high, about twice that of stainless steel and common steel, twice that of iron, and six times that of aluminum. In a world of ultra-low temperatures, titanium becomes harder and more superconductive, while steel becomes weaker and less capable. They have corrosion resistance, with no rust. Titanium does not rust in the sea for five years, while steel corrodes and deteriorates in seawater. The thermal conductivity of titanium is about the same as that of stainless steel. They are non-allergic materials. Titanium is a harmless material to the human body. More because it does not have an allergic reaction to the human body, it is one of the few metal materials used in medical science.
