Anti-reflective and oleophobic treatment, which is essential?
Anti-reflective coating, also known as AR (Anti-Reflection) coating, is a process of depositing a thin layer on the surface of eyeglass lenses. This layer helps to reduce unwanted reflections from light sources, such as sunlight or artificial lights. Together with oleophobic treatment, anti-reflective coating increases the amount of light that passes through the lenses, while at the same time reducing reflections that can hinder vision. Let’s find out together what they consist of and what benefits the anti-reflective and oleophobic treatment offers.
Oleophobic treatment, what does it consist of and what benefits does it offer?
Both dirt and grease are the Worst enemy of lenses. There is nothing more annoying than having glasses with so-called “halos”.
The oleophobic treatment ensures that the surface of the lens has less adhesiveness against liquid and oily substances.
It is an anti-dark spot treatment that simplifies the care of glasses. This process makes the lens surface more slippery, preventing dirt from adhering to it. This means that you will spend less time cleaning the lenses.
The chemical process applies a water-repellent coating to surfaces, making them resistant to oils and greasy agents. This coating creates a barrier that prevents oily substances from penetrating the surface, while reducing the formation of stains and fingerprints. This treatment is also often used to protect touch screens, glass, metal and plastic surfaces and offers the following benefits:
- stain resistance. The oleophobic treatment repels oils and oily agents, reducing the formation of stains on treated surfaces. This is also particularly beneficial for surfaces such as touch screens, which are often prone to fingerprints and grease stains.
- Easy cleaning. Surfaces treated with an oleophobic coating are easier to clean. To prevent oils and greasy agents from adhering to the surface, a soft cloth is sufficient to easily remove dirt, reducing the need for harsh cleaning agents.
- Duration of cleaning. The oleophobic treatment creates a long-lasting barrier, which keeps surfaces clean for a longer period. This means that frequent cleaning can be reduced.
- Corrosion protection. The treatment not only protects against stains, but can also offer some corrosion resistance. This is especially useful for metal surfaces, which can be prone to damage from corrosive agents in the environment.
Anti-reflective treatment, what does it consist of and what benefits does it offer?
Anti-reflective coating is one of the many coatings that is added to the prescription lens, in the form of a transparent and very thin film. This treatment, by positively interfering with the artificial and natural lights that surround us, reduces the amount of reflections on the lens. In this way it manages to pass more light (making the image perceive brighter) and makes the lens much more transparent, therefore aesthetically superior.
It is often believed that anti-glare is only for the sun. In reality, this treatment serves to remove any type of reflection from the lens, to allow clearer vision, both day and night.
The anti-reflective coating offers the following benefits:
- improves visual clarity. By reducing reflections, the anti-glare treatment improves the sharpness and clarity of the images we see through the glasses. This allows you to enjoy a more defined and detailed view.
- It offers greater visual comfort. Glasses with anti-reflective coating reduce eye fatigue caused by reflections. This is especially useful in bright lighting situations or when using digital screens, such as computers or smartphones, as it reduces strain on the eyes.
- It offers a better aesthetic appearance. The anti-reflective coating also reduces reflections on the surface of the lenses, allowing others to see your eyes without interference. This can improve the overall appearance of the glasses, making them look more transparent and more attractive.
- Makes cleaning easier. Glasses with an anti-reflective coating are easier to clean than those without a coating. This treatment reduces dust buildup, fingerprints, and smudges on the surface of the lenses, allowing for faster and easier cleaning.
Anti-reflective lenses, do they improve and relax eyesight?
When we talk about the performance of anti-reflective lenses, we mean the response they will have in various light situations, mainly artificial: television, computers, driving, work in indoor spaces (offices, banks, hospitals and so on). In these environments , the light emitted by lamps, screens and machinery can make the viewing experience unpleasant.
The light emission of the lamp on you or perhaps behind you while you study or work, can create so-called “ghost images” by reflecting on the back face of the lens. These are annoying luminous halos that contribute to visual fatigue and the so-called asthenopia (headaches, eye burns, eye heaviness). By adding a valuable anti-glare to your lens, you can eliminate these annoying ghosts. At the time of purchase, it is essential to check that the lens is treated both anteriorly (a feature present in almost all treatments) and posteriorly.
When driving, the anti-reflective treatment becomes “synonymous with safety”: the promptness in responding to the glare of the headlights of cars coming in the opposite direction, the increased contrast in the darkest areas and the cleanliness in the image that is projected on our eye are just some of the advantages that anti-reflective can give to drivers.
Anti-reflective coating for prescription lenses, is it essential?
The anti-reflective treatment of prescription lenses is essential if what you want to achieve, wearing corrective glasses, is a Optimal 360° vision.
The anti-reflective lenses , in addition to ensuring greater performance continuity of the entire optical systemor, by canceling the disturbing effect of the ghosting images produced by reflection, are able to return a clearer, sharper and brighter vision.
The anti-reflective treatment must, therefore, be carried out on all prescription lenses, being extremely recommended (indispensable) in cases of:
- lenses with medium-high corrective power
- Driving in the evening/night hours
- Carrying out activities with VDUs
- High prismatic lenses
- anisometropia (eyes with different refractive index).
