How to Choose the Right Lens Material for Prescription Safety Glasses with Light-Adjusting Polarized Occupational Progressive Trifocals


Prescription safety glasses with light-adjusting polarized occupational progressive trifocals are a popular choice for people who need to wear glasses at work. These glasses provide optimal vision in different lighting conditions, minimize glare and enhance visual clarity. However, choosing the right lens material can be a daunting task as there are several options available in the market. This guide provides an overview of the different lens materials and their features to help you make an informed decision.

Lens Materials


Polycarbonate is a popular choice for prescription safety glasses as it is shatter-proof and resistant to impact. It is also lightweight and provides 100% protection against UV rays. Polycarbonate lenses are ideal for those working in hazardous environments such as construction sites or factories where there is a high risk of flying debris or projectiles. They are also a good choice for those working outdoors as they provide protection against the sun’s harmful rays.


Trivex lenses are similar to polycarbonate lenses in that they are lightweight and impact-resistant. However, they provide better optical clarity and are more scratch-resistant. Trivex lenses are a good choice for those who need a higher level of clarity and precision such as scientists, doctors or engineers.


CR-39 is a traditional plastic lens material that is still being used in safety glasses. It is lightweight and provides good optical clarity. However, it is not as impact-resistant as polycarbonate or trivex lenses and can break easily. CR-39 lenses are a good choice for those who need safety glasses for indoor use only and have a low risk of impact or debris.


Choosing the right lens material for your prescription safety glasses is crucial for your safety and comfort. Polycarbonate and trivex lenses are ideal for those working in hazardous environments or outdoors, while CR-39 lenses are suitable for indoor use with a low risk of impact. Consider your work environment and visual needs before making a decision. Remember to ensure that your lenses are light-adjusting and polarized occupational progressive trifocals, giving you the best possible vision whatever the light.

Additional Tips
