The advantages of Tr90 frames

The TR90 frame is made of a polymer material with memory, which is the most popular ultra-light frame material in the world. It is super tough, resistant to impact and wear, and has a low coefficient of friction, which can effectively prevent damage to the eyes and face caused by frame breakage and friction during sports. Due to its unique molecular structure, it is chemically resistant and is not easily deformed in high-temperature environments, can withstand temperatures of up to 350 degrees for a short period, and does not melt or burn easily. No chemical residues are released and it meets the European requirements for food-grade materials. Tr90 frames have a lubricated surface, float in salt water, and are lighter than other plastic frames, less than half the weight of sheet frames, and 85% of nylon, reducing the burden on the nose and ears and making them suitable for teenagers. Products made from TR90 are wear-resistant, chemically resistant, solvent-resistant, weather-resistant, non-combustible, heat-resistant, and not easily deformed.

Selection of Tr90 frames

1. Sizing: Tr90 frames also come in their size. The size of the frame is usually indicated on the temples, nose bridge, or on the label. First of all, you should know the size of the frame that suits you, either by checking the parameters of the glasses you have purchased, by using a ruler to measure the glasses you have been fitted with to get the data, or by going to an optician to try them on and then writing down the size that suits you.

   
   

2. If the lenses are too far from the eyes, not only will the optics change, but the wearer will also see the outside of the lenses, making positioning difficult; if the lenses are too close to the eyes, the eyelashes will touch the lenses, which will not only cause them to blur but also cause irritation.

   
   

3. The angle between the front mirror of the glasses and the vertical line of the wearer's face is about 4° to 18°, and the size of the angle is related to the field of vision. Generally speaking, the upper part of the Tr90 frame cannot touch the eyebrows and the lower part cannot touch the face.

   
   

4. The width of the nose bridge frame of the glasses is moderate, and consumers can detect it by themselves when selecting the frame by the following methods: keeping the head vertical and gazing forward, the frame can maintain a satisfactory position without any clamping of the mirror legs.
