Coatings: improvement in lens construction
People who depend on their lenses to function well on a daily basis know the importance of choosing a quality option. One way to ensure that lenses fit the user’s needs are coatings. Thanks to this specialized treatment you will be able to take your glasses to the desired level.
It is a technology that has gained territory in optics, despite the fact that it is widely used in camera lenses. We will explain what it is and how it benefits the user.
What are the coatings?
Coatings are coatings that are applied to an optical object such as the glass of formulated lenses. It consists of different chemical materials placed in layers. The purpose of this procedure is to provide extra qualities to the mica.
What coatings allow is to personalize the glasses according to the particular lifestyle. It’s like adding a property that you need to feel comfortable with its daily use. Some of the most common are:
- Antirrayone
- Anti-scratch.
- Anti-reflective.
- Anti UV rays.
- Blue light filter.
- Clear coat.
- Water repellent.
The crystals are introduced into a chamber that has a disc where the micas are embedded. When the machine starts its treatment cycle, a vacuum effect is produced. The lens coating is then sprayed by applying one layer on top of another with drying intervals at high temperatures.
How are coatings used in contemporary ophthalmology?
Basically, glasses coatings are used to improve the quality of vision in certain external circumstances. Toughening the glass from multi-layer coating treatments is useful to increase durability. Avoiding scratches and fractures is important when we wear glasses all day.
But, there are other more specialized ones, which is clear coat, a finish with hydrophobic and antistatic functions. Prevents the adhesion of dust, lint and water droplets. The procedure smoothes the surface to such an extent that the particles slide off. In addition, they are less prone to oil accumulation and fingerprints.
Today, it is possible to combine the benefits of all coatings in one lens. Typically, 8 to 10 layers of coatings with different attributes are attached to a single glass. First, a coating base is used on which the others rest.
Advantages and benefits of using coatings
The innovative finishes provided by optical coatings turn ordinary lenses into truly pieces of advanced engineering. It is an advance that has implied a revolution in the world of contact lenses. You can check it by considering the following advantages:
- Sharpness: Seemingly insignificant factors such as water droplets, fingerprints or dust can reduce visual sharpness. But, coatings solve this problem by providing an extra smooth glass that repels particles and grease.
- Durability: the layers give it greater resistance to shocks, avoiding possible fractures of the mica. They are also difficult to scratch with other hard objects because the multi-layer structure forms a strong barrier.
- Protection: it is proven that UV radiation causes serious damage to the ocular anatomy. Coatings with UV filters protect 100% from this harmful exposure.
- Personalization: these and other benefits can be configured according to the needs of each user, paying attention to their way of life.
Final considerations
In short, coatings are a mandatory addition to formula lenses. Coatings function as a resource to optimize the effects of the prescription.
Multilayer technology increases the comfort, aesthetics and effectiveness of eye treatments, diversifying the glasses customization alternatives.
