Coating color is an important element that optical lens buyers and suppliers pay close attention to.
However customers are unaware of the differences between different colored coatings.
This article aims to help users better understand the different coating colors available on lenses and the differences between them.
1. White Coating:

A white coating means the lens reflects white light. This coating color is commonly found in the UC and HC of semi-finished lenses.
It achieves basic light transmittance. However, without an AR anti-reflective coating, it is prone to glare, resulting in lower visual comfort.
Furthermore, UC, lacking a protective coating, is more prone to scratches. In contrast, HC has a hard coating, resulting in a longer lifespan and less susceptibility to wear.
2. Blue Coating:

Blue-coated lenses reflect blue light and are one of the most commonly used coating colors by optical distributors and wholesalers.
Compared to white coating, it has higher light transmittance and better anti-reflective properties, increasing lens comfort. The coating also prevents scratches and improves lens durability.
Normally blue coating will increases the lens base color, because it will reduce lens transmittance. But Trust Industrial is producing the real none base blue coating since the year of 2024.
3. Green Coating

Green-coated lenses reflect green light and are one of the most commonly used coating colors by optical lens distributors.
Like blue coating, it offers higher light transmittance and excellent anti-reflective properties, increasing lens comfort.
The coating also prevents scratches and improves lens durability. Compared to blue coating, it has better light transmittance and a lighter base color.
4. Red Purple Coating

Red purple coating, due to its more balanced spectral control and better anti-glare effect, is commonly used in driving lenses.
It effectively reflects and cancels ground reflections and stray light, providing users with a better visual experience.
In addition, it can reduce the light transmittance of the lens and increase the background color, thereby improving visibility when driving at night.
Making the edges of objects clearer, and helping users maintain a good visual experience while driving.
5. Front Blue Back Green Coating

This type of coating combines two films: HMC blue and HMC green. The blue coating effectively blocks blue light, protecting the eyes from harmful blue light.
The green coating increases lens transparency, making the lens clearer.
This type of coating is suitable for users who require both blue light protection and clarity. One lens can achieve both effective blue light blocking and clear vision.
6. Gold Coating

The gold coating is a newly developed coating. Its unique color has made it popular with customers who value fashion and individuality.
Besides its unique color, it has higher light transmittance than ordinary HMC coatings, is waterproof, and easy to clean, making it a better choice for high-end lenses.
These are the main coating colors you might encounter. Different colors offer different lens functions.
The choice depends primarily on the user’s desired functionality; different colored coatings offer different functions.
