What are organic glasses?
Do you need new glasses? The choice of glasses requires a lot of thought. There are many options when it comes to correcting lens material. Most eyeglass lenses these days are organic lenses. But what exactly do we know about organic glasses?
Facts
Organic glasses are synthetic glasses commonly known as "plastic glasses". These glasses are obtained from synthetic resin, which is formed by macromolecules of organic bonds. The heart of the manufacturing process for his correction glasses is the "Duromer".
The first glasses with organic lenses were released in 1947. The material used for their manufacture is CR39. It is a plastic polymer, the very first of its kind, used to make organic glass. Its name comes from the PPG company that markets it. Over the years, the manufacture of organic glass has expanded to other materials while further improving the refractive index and other physical properties. Organic glasses have evolved over time and use the technologies available to become more efficient. The refractive index of this type of glass is the benchmark. If the first models were quite thick, we can now get very thin models to ensure aesthetics.
Organic lenses are the most common in the eyeglass lens market today. They are just as good for either sex, regardless of the age of the wearer. At Visio-net we offer you a wide range of organic glasses that can be easily adapted to your use and style. Glasses or sunglasses, do not hesitate to consult our collection and ask for advice if necessary.
The different types of organic glasses
CR39 was the first material used to make glasses with organic glass. Today you can choose between several options. Each of the materials listed below has its advantages and disadvantages in making corrective lenses. Regardless of your choice of organic lens material, a wide range of models is available to you from our collection of 10,000 corrective glasses and 12,000 sunglasses.
CR39
The CR39 was marketed from 1947 by the PPG company who discovered it. Its name comes from the study "Colombia Resin", which made it possible to manufacture this material. The number 39 refers to the 39th attempt that produced the material. Together this makes CR39. To this day, this material is most commonly used to make organic glasses. We mention its lightness and its good price-performance ratio as an advantage. By default, we list the poor UV protection.
MR8
After CR39, the organic glass market is dominated by MR8 in second place. This material is characterized by its versatility. It offers good UV protection and excellent resistance. It is 8 times more impact resistant than CR39. This material for all types of corrective lens treatments. It is especially recommended for corrective glasses with a pierced frame. The only flaw is that it is more expensive compared to the CR39s
Trivex
Trivex or PNX is a material with properties close to MR8. Like CR39, Trivex is also a material that was developed by the PPG company. This material, which is not widely available on the market, deserves to be known. It offers 100% UV protection and offers optimal resistance. This material is not afraid of alcohol and chemical solvents, which is not the case with all, especially polycarbonate. Its shortcomings are its thickness and its high cost.
Polycarbonate (made from bisphenol A)
Finally, there is polycarbonate, a material known for its impact resistance and UV protection. The market for this material is taken over by MR8. In terms of optical quality, this material is not recommended unless otherwise specified by a specialist (ophthalmologist). This material is mainly used for the production of protective glasses or sports glasses. Note that this material is scratch-sensitive without treatment.
The benefits of using organic glasses
Organic lenses have become a darling in the eyewear market for several reasons. You should know that this type of glasses has many significant advantages.
Ease
When we talk about organic glasses, the first benefit that comes to mind is lightness. In fact, organic glasses are lighter than mineral glasses. This is the strength that has brought this type of lens to the fore in the eyewear market. This ease makes it convenient for all user profiles, adults or children.
Resistance
Organic glasses are not only light, they are also shock and break resistant. For this reason, this type of glass is recommended for sports activities. This is also a great advantage for children's glasses. It should be noted, however, that this type of glass is sensitive to scratches if handled correctly.
UV protection
UV rays are good for the body unless you are excessively exposed. This is especially the case in extreme heat. Long exposure can damage the eyes. This is why organic glasses are very interesting because UV filtration is optimal, ie a filter at approx. 95%. Note that the UV protection does not take into account the colour tones of the lenses.
Multiple use
Organic glasses are highly regarded for their adaptability. It can be used for different activities every day, in all seasons and ages. A quality that is not available for mineral glasses is prohibited for persons under 16 years of age. For their part, organic glasses can benefit from different types of treatment to adapt to needs.
Aesthetics
Glasses can add significant value to your look. It is also important to choose the glasses that make up your glasses. The lightness of organic glasses is explained by the low material thickness. This is a plus for the overall aesthetics of these devices.
We have specialists who can advise you on the best options based on your use and needs.
Surface treatments for organic glasses
No matter which eyeglass lens you choose, each one has a weakness. To correct this, surface treatments are offered. There is a specific type of treatment for each problem. Fortunately, organic glasses are great for surface treatments.
Anti-scratch treatment
Anti-scratch treatment has priority when buying organic glasses. You should know that this type of glass is very sensitive to scratches. The purpose of this treatment is to harden the surface by adding varnish and to extend the life of the glasses. Thus, the glasses are more resistant to scratches and friction.
Anti-reflective treatment
The eyes are usually exposed to light reflections. Applying anti-reflective treatment will help you see better by improving the perception of contrasts. The visual comfort is especially useful for driving and computing. In addition, it reduces eye fatigue and headaches caused by reflections from glasses.
Polarizing sun treatment
With polarized sunglasses you have better visibility by reducing glare. This is a special feature that proves to be useful in everyday life and especially in sports practice. If you are into water sports and are in the mountains, this treatment is recommended.
Tint
This glass surface treatment primarily fulfils an aesthetic need. However, depending on the colour chosen, this treatment also offers visual comfort. Colours are divided into two categories, namely neutral tones and vivid tones. Neutral tones like brown and grey are ideal for improving visibility in sunny weather. In lively tones, yellow and orange are recommended.
Note that organic glasses offer good protection against UV rays, i.e. 95% versus 85% for mineral glasses. However, you still have the option of UV treatment if you want to improve this ability.
The choice of organic glass frames
Another benefit of organic glasses that hasn't been mentioned is the ability to be mounted on different types of frames. You can opt for a round or rectangular model made of metal or acetate. As mentioned above, pierced frames work well with organic glasses. This type of frame offers discretion and is elegant at the same time. The ease is pleasant. Otherwise you can always opt for a frame, a timeless classic.
