Lunor - Glasses For Men

Many of Lunor's metal frames are made from high-quality titanium, gold, and stainless steel. In addition to the special process of making titanium, all-metal frames are made by hand in a factory in Germany, fully reflecting the craftsmanship and thought behind the production of the brand. The texture and professional demeanor of the glasses are strong. The brand is very good at combining classical and modern. What we can see is that the nose pad and the frames are made of pure titanium, so there's no allergic effect.


Why are titanium glasses so expensive?

Light Weight. The term 'pure titanium' means a titanium metal material with a purity of more than 99%. A mineral containing titanium was found in 1791, but pure titanium was not produced until 19. Pure titanium glasses are lighter than titanium alloy glasses. For frames of the same design or appearance, titanium frames weigh only half as much as other ordinary metal frames, reducing the load on the bridge of the nose.



Operation and Requirements of Drop Ball Test

The ball, which is 0.625 inches in diameter and weighs 0.56 ounces (16 grams), falls from 50 inches (127 centimeters) and hits the center of the lens. The geometrical center of the lens should be struck by the ball within a circle 5/8 inches in diameter. If the lens does not break, it is called a safety lens. There can't be anything that restricts the ball from falling. It cracks across the entire thickness, containing laminated layers (if any), and divides into two or more separate sections across the entire diameter.
