PC material or resin material is more suitable for glasses

1. Priority is given to the use scenarios: choose resin lenses for daily static eye use; choose PC lenses with high sports and impact resistance or children's glasses. Differences in core performance (1) Impact resistance and safety performance PC lenses: The impact strength is more than 10 times that of conventional resin lenses. It has passed the U.S. FDA6-meter ball drop test and will not form sharp fragments after fragmentation, which is a safety-protective lens.

2. PC lenses are more resistant to falling than resin lenses. They are not easily fragmented when subjected to strong impact, providing greater safety. PC lenses have very good light transmission, with a light transmission rate of 92%, which ensures clarity of vision and is more conducive to eye protection. PC lenses are lighter than resin lenses and provide a more comfortable experience when worn, making them especially suitable for users who wear glasses for a long time.

3. The core differences and application scenarios between the two are as follows: Impact resistance and safety performance The impact strength of PC lenses is more than 10 times that of ordinary resin lenses. After fragmentation, it is not easy to produce sharp splashing fragments. It is more suitable for children, outdoor sports enthusiasts, etc. People who are prone to bumps; ordinary resin lenses have weak impact resistance and are easy to break after strong impact.

Are glasses afraid of high temperatures?

1. YesWill pc glasses burst?theWill pc glasses burst?, most daily used eyeglass lenses are afraid of high temperatures. The high temperature resistance of lenses of different materials varies greatlyWill pc glasses burst?: Resin lenses (mainstream material): the most common but also the most afraid of high temperaturesWill pc glasses burst?Lens deformation, coating blisters and even cracking may occur when exposed to light for a long time or close to a fire source. For example, if glasses are left in a car under the windshield in summer, damage will be caused if the temperature inside the car exceeds 60 ° C.

2. Recommendation: Although eyeglass lenses are not easily damaged by high temperatures, they areWill pc glasses burst?In order to avoid unnecessary risks, users are advised to avoid exposing their glasses to high temperatures for long periods of time during daily use, such as not placing their glasses on the dashboard of a car (especially in summer with direct sunlight) or close to high temperature sources such as stoves. At the same time, when cleaning and maintaining glasses, appropriate temperatures and methods should also be used to ensure the performance and life of the lenses.

3. Glasses are generally afraid of high temperatures. First, high temperatures may affect the optical properties of the lens. For example, some resin lenses may undergo slight deformation at high temperatures, resulting in inaccurate degrees and affecting the visual correction effect. Secondly, high temperatures may damage the film on the lens surface. For example, adding hard films, anti-reflective films, etc., high temperatures will accelerate the aging and peeling of the films, reducing the wear resistance and clarity of the lenses.

4. Glasses are generally afraid of high temperatures. High temperatures will cause some changes to the eyeglass lenses. First, it may cause damage to the lens film. For example, for some lenses with a hard coating, the film layer may peel off at high temperatures, which affects the clarity and wear resistance of the lens. Secondly, high temperatures may change the optical properties of the lens, such as slightly changing the refractive index of the lens, which in turn affects the vision correction effect.

Which is better between PC eyeglass lenses and resin eyeglass lenses

1. ItsWill pc glasses burst?It features PC lenses with better heat insulation and ultraviolet protection performanceWill pc glasses burst?, high temperature resistance is better than resin; resin lensesWill pc glasses burst?higher initial light transmittanceWill pc glasses burst?, and the anti-yellowing aging technology is more mature, and the degree of yellowing after long-term use is lower.

2. Resin lensesWill pc glasses burst?: Resin lenses with conventional refractive index of 56-67 have weak impact resistance and are prone to produce sharp debris after being broken by external force, posing a risk of scratching the eyes. (2) Optical performance resin lenses: The light transmittance can reach 92%-95%, the dispersion coefficient is high, the rainbow pattern and deformation are lower when viewing objects, and the visual comfort is better.

3. PC lenses have obvious advantages in eyeglass materials. They have higher strength than ordinary resin lenses, excellent impact resistance, are more wear-resistant, and are more resistant to falling. PC lenses are light in weight, about one-third of that of resin lenses and about half of that of glass lenses, reducing the burden on glasses and improving comfort. PC lenses have 100% UV protection, have strong oxidation resistance and are not easy to change color, while resin lenses require additional film treatment.

4. PC lenses (polycarbonate) are like "bulletproof armor". The impact resistance is more than 10 times that of resin and the thickness is reduced by 30%. However, the surface layer is more likely to be scratched and requires additional hardening treatment. Suitable for priority: Office workers/student parties preferred resin lenses: When working at a desk or frequently using electronic equipment, the anti-blue light coating is superimposed to protect the eye. The price is mostly in the range of 100-500 yuan, and the pressure of long-term replacement is small.
