CR-39 Lens Property

HONGCHEN CR-39 lenses use the true value of imported CR-39 monomer, the longest history of organic material and the most widely sold lens globally. This determines that HONGCHEN CR-39 lenses have the most 
outstanding optical features:

The best among other organic lenses in hardness and toughness, high impact resistance.
The highest transmittance as compared with other organic lenses.
The highest ABBE value providing the most comfortable visual experience.
The most reliable and consistent lens product physically and optically.

CR39 (Plastic) Advantage

 -Lightweight organic material

 -Very good optical performance even for high prescriptions

 -Suitable for working with chemicals and paints / varnishes

 -Mechanical strength class "S" (falling ball test)

 -Good scratch resistance due to hard layer (optional)

 -The middle of the lens should always be thicker in order to meet the requirements for tensile strength

1.5 index

Our regular 1.5 index CR39 lenses are plastic and suitable for general purpose. These lenses offer outstanding optical quality and durability.

CR39 is most basic lens type. It’s ideal for normal prescriptions. 

This lens is made of CR-39 plastic, which is a polymer (a large molecule composed of many repeated subunits, known as monomers). HEre’s a fun fact, CR-39 gets its name because it was the 39th formula of a plastic developed by the Columbia Resins (hence “CR”) project in 1940.

Product Feature

What are progressive lenses?

Progressive lenses are no-line multifocal eyeglass lenses that look exactly the same as single vision lenses. In other words, progressive lenses will help you see clearly at all distances without those annoying (and age-defining) "bifocal lines" that are visible in regular bifocals and trifocals.



The power of progressive lenses changes gradually from point to point on the lens surface, providing the correct lens power for seeing objects clearly at virtually any distance.

Bifocals, on the other hand, have only two lens powers — one for seeing distant objects clearly and a second power in the lower half of the lens for seeing clearly at a specified reading distance. The junction between these distinctly different power zones is defined by a visible "bifocal line" that cuts across the center of the lens.

Progressive lenses are line-free multifocals that have a seamless progression of added magnifying power for intermediate and near vision.

Progressive lenses sometimes are called "no-line bifocals" because they don't have this visible bifocal line. But progressive lenses have a significantly more advanced multifocal design than bifocals or trifocals.

Premium progressive lenses (such as Varilux lenses) usually provide the best comfort and performance, but there are many other brands as well. Your eye care professional can discuss with you the features and benefits of the latest progressive lenses and help you find the best lenses for your specific needs.

Progressive Lens Benefits

Progressive lenses, on the other hand, have many more lens powers than bifocals or trifocals, and there's a gradual change in power from point to point across the surface of the lens.

The multifocal design of progressive lenses offers these important benefits:

  • It provides clear vision at all distances (rather than at just two or three distinct viewing distances).
  • It eliminates bothersome "image jump" caused by bifocals and trifocals. This is where objects abruptly change in clarity and apparent position when your eyes move across the visible lines in these lenses.
  • Because there are no visible "bifocal lines" in progressive lenses, they give you a more youthful appearance than bifocals or trifocals. (This reason alone may be why more people today wear progressive lenses than the number who wear bifocal and trifocals combined.)
