Is mirrored or polarized better?

Translucent colored sunglasses

Sometimes we opt for sunglasses to hide gaunt dark circles and no-makeup eyes, and when we want to wear sunglasses with delicate makeup, the translucent texture seems to be the best choice. The translucent shades that were on show this year were more colorful, like another layer of eye shadow. You can instantly choose from a wider range of colored sunglasses, which can be paired with a variety of colors according to your style and come with a retro filter effect.

You can also ask those who wear varifocal glasses to give you some advice.



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.


How can I measure the frame size?

Use a ruler to measure the glasses you used to wear comfortably and record the width of the frame and the total width in front of the frame. And compared with the frame width of the selected frame and the total front width of the frame. Frame width size difference of one or two millimeters does not matter, and the total front width of four millimeters does not matter. You can use a ruler to measure the approximate distance between the temples. Usually, the width of the inner side of the frame is the same as the temple value or about 3MM larger than the temple value.



Design principle of progressive multifocal lens

For the same piece of the lens, the top is used to see far, the bottom is used to see close. The upper and lower degrees are different.

There is not a sudden change in the distance degree fixed above the lens to the near degree fixed below the lens, but a gradual transition between the two through gradual changes in refractive power, which has special benefits over common bifocals or trifocal lenses.


Proper massage

Proper massage can not only relieve the fatigue of the skin that supports glasses but relax the eyes. Take time each day to gently massage the marked area of the nose pad for ten minutes. Try not to wear glasses all the time. You can switch between contact lenses and glasses. In this way, over time, the nasal plate marks will gradually disappear. Hot towels can be used to warm the skin, which is helpful to blood circulation to the skin and slowly eliminate indentation.

Retro glasses with thick frames

This type of frame is the same as the one above, except that the frame is a little thicker, which is more suitable for students. But be careful not to choose the border that is too thick, otherwise, it will appear rigid and dull.
