When should I get polycarbonate lenses?

For anyone who is purchasing glass lenses, make sure they have this additional coating to safeguard your eyes from the Ultra violet rays. It is actually important to note that a lot of people cannot even tell the difference in the clarity between glass and polycarbonate lenses nowadays. Polycarbonate lenses have come a long way since their creation and so are actually considered the typical lenses in the sunglasses industry. Plastic lenses, also referred to as CR-39, are preferred for many applications thanks to their high optical clarity, low priced, durability, and impact resistance.

• In all the lens materials on the market, glass is the most scratch-resistant.
• In addition, polycarbonate lenses intrinsically provideprotection against Ultra violet rays without having to use a special coating.
• The UV treatment is easy to put up the
• Tinting is a process useful for applying UV coating in lenses to make UV resistance.

They are able to even be constructed with fashionable ultra thin frames due to the strength of Polycarbonate. They have an increased index of refraction than CR-39, which means they refract light more effectively.

Lighter Lenses

Polycarbonate lenses are slightly more expensive than standard plastic lenses. However, since they have UV protection built-in, you don’t have to cover added protection. The material also offers a high abbe value, meaning it manages light dispersal better than other materials. Light dispersal measures look at color and light distortions in lens materials. The higher the abbe value, the less dispersion and distortion. Trivex has an abbe value of 43–45, while standard polycarbonate comes with an abbe value of 30.

• This assists you determine if you might benefit from Trivex or if you can get good vision with simple polycarbonate lens options.
• If you’re like the majority of, you probably put far more thought into selecting your frames than your lens material.

Polycarbonate is the standard choice for almost all eyewear that will require shatter and/or chip resistance. However, thinner lenses won’t necessarily mean they’ll weigh less. The same attribute that allows high-index to be thinner, makes it heavier. With all things equal, polycarbonate is around 18% lighter than high-index. If you want safety glasses, consult an optician who is able to let you know which frames are safety rated. Polycarbonate and Trivex lenses both block completely of the sun’s Ultra violet rays with no need for special UV-blocking lens coatings.

Exactly What Is A Polycarbonate Lens?

If the optics aren’t as clear as glass, it’s polycarbonate. Polycarbonate lenses have less Abbe value of 30, providing them with a higher dispersion value which also causes chromatic aberrations. High-index lenses contain a unique aspheric design which facilitates a flatter lens curvature, leading to reduced magnification and improved appearance.
Polycarbonate lenses are far lighter than traditional plastic and glass lenses, ideal for people who have higher prescriptions. Another reason behind their lightweight is that the glasses are comparatively thinner. Over time of its introduction, polycarbonate began to gain traction for its durability and extra properties. You can add a number of different coatings and treatments to polycarbonate lenses, including anti-reflective coatings and blue-light-filtering coatings. Polycarbonate lenses can also be progressive lenses, which feature multiple zones of vision correction.
