Why do blue light glasses turn yellow?

The glasses are used for a long time. Blue lenses are usually light yellow. If the yellow is too deep, the resin lenses will oxidize and become yellow due to the long-wearing time. The lenses need to be replaced in time. Yellowing of the lens is related to the excessive secretion of facial grease, which leads to yellowing of the lens. The most direct way is to replace the lens glass.


Production technology of progressive lenses

In addition to the evolution in design, the production technology of progressive lenses is also constantly improving: the most representative one is the free-form technology. The emergence of free-form surface technology makes the production more flexible and rapid and can realize a more personalized design. For now, progressive lens design is done on the inside surface of the lens by a computer-controlled lathe, as if a master engraver could carve a piece of stone into a work of art.



Two Tone Thick Frame Glasses

These two tone chick frame glasses are deliciously composed of two-toned acetate. The stylish oval lens frames feature a semi-transparent tortoiseshell finish melded with a creamy white. A classic keyhole nose bridge, two rivets stud accents, and comfortable spring hinges complete the concept of “wear in comfort, look in style”


What Are Blue Light Glasses?

Blue light blocking glasses have specially crafted lenses that are said to block or filter out the blue light given off from digital screens. The lenses are often marked with a coating that protects your eyes from eye strain and can help reduce potential damage to your retina from prolonged exposure to blue light.



The shape of the lens is also important.

Aviator and cat-eye glasses should be avoided, as both will cut off the base of the prescription, resulting in poor reading vision. Instead, they should opt for shorter frames with rounded edges, such as bull horn frames, vintage wingtips, round frames, and oval frames.


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.

Why do people like wearing rimless glasses?

Suitable for a Variety of Face Shapes. The rimless glasses can perfectly present the lens without the wrapping of the frame, hence, they are very ornamental. Rimless glasses work on all face shapes, even if you have a heart-shaped face, a round face, a square face, or the enviable oval face. Compared with thick-rimmed glasses, rimless glasses do not cover too much face shape and can show the wearer's style and temperament. People with small faces will have a better wearing effect.
