Which Is More Expensive Frames Or Lenses?

Progressive lenses and single vision lenses

An optical lens that has only one luminosity on a single vision lens and does not have special functions.

The curvature of the front surface of the progressive lens increases continuously from top to bottom, and the refractive power increases gradually and continuously from the distance zone located on the upper part of the lens until the near zone at the bottom of the lens reaches the required near-use refractive power. A pair of glasses can be used. You can see far away, you can see close, and you can see objects in the middle distance.

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.

Your glasses are not symmetrical.

If one side of the frame looks higher than the other, you need to adjust the arm. If the right side is higher than the left, gently bend the left arm at the hinge or where the arm bends behind the ear. If the left side is higher than the right, gently bend the right arm at the hinge or where the arm bends behind the ear. Adjusting the frames a little at a time may damage your glasses. Place your arms in warm water to make them easier to adjust. Use only warm water from the tap. Don't use boiled water! Because it affects the coating on the lens. If one adjustment is not in place, it can be adjusted several times, and the above methods can be comprehensively used. If the adjustment is really bad, then you have to go to the optical shop to ask the staff to adjust.
