The amazing features of anti-glare coatings

Anti-glare coatings, also known as anti-reflective (AR) coatings, are applied to eyeglass lenses to reduce reflections, improve clarity, and enhance vision. Here are three common types of anti-glare coatings:

1. Basic anti-glare coating:

This is usually standard for anyone who wants to get glasses. Basic anti-glare coating makes sure that your lens does not have glare that lets you see clearer and look better. There won’t be reflection when people see you and light would not have a distracting halo effect when you see light at night and especially while driving. Most of the time, basic anti-glare coating includes UV light protection on it.

2. Oleophilic and Hydrophobic Anti-Glare Coating:

Hydrophobic coatings are designed to repel water and moisture from the surface of the lens. This feature helps to prevent water droplets from sticking to the lens, which can obscure vision, especially in rainy conditions or when moving between temperature extremes. Hydrophobic coatings also make the lens easier to clean, as water and dirt are less likely to adhere to the surface. This type of coating is particularly useful for outdoor activities and for individuals who live in humid environments.

Oleophobic coatings are similar to hydrophobic coatings but are specifically designed to repel oil and grease. These coatings prevent fingerprints, smudges, and other oily residues from adhering to the lens surface, making it easier to keep the lenses clean and clear. Oleophobic coatings are particularly beneficial for individuals who frequently handle their glasses or who have oily skin. They can also help reduce glare caused by oily residues on the lens surface.

Coating brand that are oleophilic and hydrophobic are Essilor's Crizal brand, Zeiss’s Duravision, and Hoya’s EX3 

3. Blue Light Blocking Anti-Glare Coating:

Blue light blocking coatings are designed to filter out a portion of the blue light emitted by digital screens, LED lights, and other sources. Blue light is known to contribute to digital eye strain, disrupt sleep patterns, and potentially cause long-term eye damage. By reducing blue light exposure, these coatings can help alleviate eye strain, improve visual comfort, and promote better sleep quality. Some blue light blocking coatings have a subtle yellow tint, while others are virtually clear. They are particularly popular among individuals who spend a lot of time in front of computers, smartphones, or other digital devices.

Brands are Essilor Prevencia, Zeiss’s Blueguard, and Hoya’s Recharge. 

These are just a few examples of anti-glare coatings available for eyeglasses. Depending on individual preferences and needs, there are various other coatings and treatments that can be applied to eyeglass lenses to enhance visual performance and comfort.
