TR90 material was originally made in Italy. It is difficult to color the frame, and usually, the color is painted on the outside. It can float in saltwater. It is suggested that the lens should be a water first to prevent overheating of the lens. Then, at the end of the nose, hinge, or the temple, carefully fold it in until it is comfortable to wear. You can use a household hair dryer to blow heat first, which can play the role of softening. Note that the hairdryer should be moved when heating, and do not aim at only one place. TR-90 is the most popular ultra-light material in the world at present.


Types of Progressive Lenses

At the same time, there are different types of progressive lenses and they are standard PALs, short corridor PALs, computer PALs, and Reading PALs.

Standard PALs must fit your vision needs. They can be added to frames of your choice, but you need to ensure that the frames are the right width and height proportions to grant enough space for the gradient changes in the lens.

Short corridor PALs are made to fit into smaller frames so as to suit a wider range of eyewear styles.

Computer PALs are designed for computer users and other occupations that require strong intermediate and distance vision.

Reading PALs are designed for those who enjoy reading and they can opt for a pair of lenses with a larger close vision zone.



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.

Glasses Size - Lens Height

Lens height is the length between the top edge of a lens and the bottom edge of that lens. Lens height is the distance between the lowest point of the lens and the top of the frame above it. This number may be influenced by the style of your glasses.

What Are Progressive Lenses?

Progressive lenses are designed for people who are over 40 years old. It is a blended multi-focal lens with distance correction at the top, intermediate in the middle, and reading at the bottom. The goal is for the lens to work how your eye naturally works to let you see things both close up and far away.

Progressive lenses are made with an hourglass shape so there is some blurriness on the outer edges, but since it gives you your full range of vision, it is generally better than a bifocal despite being similar.
