The glasses slid up your nose.
Although glasses often slide up your nose and pushing them up can be annoying, it's easy to pull them tight. If your nose frame is metal, use your thumb to shrink the nose pad until the frame no longer slides. If you have plastic frames, soak the arm in warm water for 30-60 seconds, then apply slight downward pressure to the end of the arm. This will make it fit more behind the ears, which will tighten the overall fit and prevent slippage. If tightening the frame doesn't work, try using eyeglass wax to stop it from slipping.
The Disadvantages of Trifocal Glasses
Here, we will show you the disadvantages of trifocal glasses. If you wear the trifocal glasses for the first time, you may spend some time getting used to them. Adjusting to wearing trifocal glasses can take some time. The different fields of vision can make them disorienting at first, but over time you will get used to wearing them and your eyes will naturally move to the prescription they need for the task at hand.

What Are Colorblind Glasses?
Colorblind means that you can’t see the depth or richness of certain color shades. Colorblind glasses are eyeglasses with specially tinted lenses that help a colorblind person to see colors more accurately. Colorblind glasses do not cure color blindness or produce 100% normal color vision. But they enhance and partially correct certain color vision deficiencies of colorblind individuals.
Color blindness is common among people, especially in men. Blindness is an inherited condition, but can also be acquired. It can also occur if the eyes are damaged due to injury or from another disease that affects vision.
Colorblind glasses claim to assist with detecting differences between colors. They also claim to add additional vibrancy to the colors that people with color blindness may not fully experience.
Are carbon fiber glasses better or titanium?
In terms of weight, the titanium frame is very light. The specific gravity of the pure titanium frame is about 4.5g/cm3, and the specific gravity of the titanium alloy frame is about 8.9g/cm3. The pure titanium frame is lighter than the titanium alloy frame. However, carbon fiber glasses are lighter in weight. The carbon fiber glasses launched by LOHO are only 7.87g, which is very light to wear.
In terms of hardness, titanium has a high hardness, about twice that of stainless steel, twice that of iron, and six times that of aluminum. Carbon fiber is lighter than aluminum, harder than steel, and its strength is ten times that of iron.
In other respects, the titanium frame has the advantages of corrosion resistance, acid and alkali resistance, high stability, good elasticity, good toughness, and resistance to deformation. The carbon fiber frame has the advantages of corrosion resistance, high temperature resistance, radiation resistance, good elasticity, good flexibility, and abrasion resistance.
It can be seen from the above comparison that carbon fiber glasses have the general advantages of titanium frames. In terms of weight, carbon fiber glasses are much lighter than ordinary pure titanium glasses.
Glasses Size - Frame Width
To really know how big a frame is, and how it will look on your face, you have to determine the width of the entire frame. The outer width of the frame is the distance between the visible areas on the left and right sides of the frame, namely, the distance between the frame and the junction of the two temples. The inner width of the frame is the distance between the inner sides of the two temples at 60mm behind the plane of the lens. This is just the contact point between the temple and the human temple. If it is too tight or too loose, it will affect the wearing comfort. The weight of the frame is evenly distributed across the bridge of the nose (or evenly distributed between the two nose pads on the bridge of the nose).
Palo Alto
They are not heavy. The glasses are not heavy at all and robust and are well-suitable. The prescription is perfect. These rimless metal glasses have a bronze finish and a perfectly rounded lens. The slender metal arms finish, and the turtle arm tips and spring hinges, make the glasses simple but stylish.
Choose the right color for your safety glasses.
If you work in a dazzling environment, do high-precision work, or work indoors and outdoors, you may need different types of colors. The right color will help your eyes adapt to the conditions and reduce the amount of focus and refocus your eyes need. If the color of safety glasses is not used correctly, eye strain may result.
