👀 Best eyeglass lens manufacturers for 2020

Glasses can be hazardous to your health if you do not pay attention to the lenses. Cheap lens materials do not restore vision, but only make it worse. This is confirmed by ophthalmologists. When buying an accessory, the refractive index, the type of raw material (plastic or glass) and the coating are considered. Having studied these parameters, a person will quickly select a safe product.

The editors of the site "bestx.htgetrid.com/en/" have prepared for you a rating of the best manufacturers of eyeglass lenses for 2020.

Pay attention to the material

Spectacle lenses are made from inorganic glass or medical grade plastic. The first option is traditional and is obtained by melting glass components. It is used in most of the products, the material is durable and reliable. There is also a disadvantage: high cost, compared to plastic models.

To impart more density, change refraction or change other technical characteristics, the chemical composition of the material changes during production.

Organic models are made from synthetic polymer materials. To increase strength and service life, special additives are used. Similar models can be made of thermosets and thermoplastics. The difference lies in the fact that the first group collapses under the influence of high temperatures, and the second only melts and solidifies if the heating is stopped.

The advantages of glass models

Glass lenses are in demand by most buyers. The positive aspects include:

• High scratch resistance due to the hardness of the material. The buyer does not have to buy a durable case made of plastic or wood. To preserve points, a regular pouch will do.
• Do not wear out over time. Plastic lenses lose their original appearance every month, especially with a careless attitude. Glass representatives are not in danger.
• Do not deteriorate from frequent exposure to sunlight or when working in a room with high temperatures.
• Good surface grip allows you to match any frame.

Mineral lenses are prescribed by doctors for those patients who have a large deviation from unity. Other options will not work for them. The reason for this decision is the high degree of refraction with a thinner material. This has a positive effect on the comfort of wearing the glasses.

But even this solution has some disadvantages:

• Fragility. Despite its wear resistance and durability, the material is easily shattered if dropped or hit against an object. The last situation is the most terrible, since the glass is close to the eyes and when destroyed, the lenses will fall into the organ. This will cause serious damage to the retina.
• Not suitable for correcting vision in children.

Features of the plastic option

When organic material first appeared, it was not widely used due to some disadvantages.Therefore, optometrists deliberately ignored it and prescribed only mineral lenses to patients. The situation changed when a new way of development was invented, which is characterized by safety and reliability. If earlier only inorganic glass was bought, now it is being replaced by polymer compounds. The efficiency of modern models is the same as that of traditional versions.

The advantages of this solution include:

• Lightweight to reduce stress on the bridge of the nose and improve comfort.
• Impact resistance is achieved due to the characteristics of the material. This increases safety, since the lenses will not fly apart into a thousand fragments on impact, which will preserve an important organ.
• You can use any dye, which allows you to get dozens of shades that are suitable for specific situations.
• Do not deteriorate from frequent exposure to ultraviolet rays.

To make the product less scratched, some manufacturers apply a thin protective layer. It increases durability and prolongs the service life of glasses by 2-3 times, compared to cheap counterparts.

What is important to know about refractive index

Thickness and volume are determined only by this parameter, but besides this, the refractive index affects the percentage of reflection from the surface. It is necessary to choose glasses correctly, as convenience depends on it.

The higher the refractive index, the better the optical properties. For example, the lens will be thinner and weigh less. However, the cost of such performance will increase.

When buying glasses at an optician's salon, it is important to adhere to the prescription given by the optometrist. It lists the recommended refractive index. For example, if a person has severely impaired vision, a model with a high indicator of this parameter is selected.

The frame also affects refraction. For example, when buying glasses with a plastic frame, it is recommended to select lenses with a lower ratio. Because the thickness will not stand out much, but the weight of the product will increase.

What lenses cover

Glasses are fragile and not always reliable. Some models break from accidental drops, while others get scratched the day after purchase. Protective coatings are applied to reduce lens wear and increase lens life.

Today, at least 6 layers are used to prevent:

• Scratching. This affects the convenience and durability of the product;
• Dirt and water build-up. This makes it easier to clean the glass;
• Dust build-up and static build-up;
• Negative effects of radiation from monitors, tablets or smartphones;
• Negative effect on eyes from bright light;
• The appearance of glare, which helps to improve transparency, and, therefore, reduces eye strain.

There can be one or 3-4 coatings. Models with a large number of protective layers are called multifunctional. They eliminate not one, but several serious problems at once. The most common practice is to apply a coating that increases strength, repels water and reduces stress on the visual organ.

Choosing the right lenses for your computer

The glow of the monitor can destroy even healthy eyes. The muscles of this organ are in constant tension, and if a person is still sitting in a bad posture and is at an unsafe distance from the monitor, the chance of developing the disease in the future increases.

Working in front of the monitor, over time, you may experience dryness, severe burning, redness, and sometimes tearing. This will have a bad effect on eye health, and no amount of vitamins will help restore the previous visual acuity.

For those who constantly work at the monitor, ophthalmologists recommend purchasing computer glasses. They are suitable for everyone, including people who do not need correction and can see perfectly far and near. A protective coating is applied to the surface of this material, which reduces the impact of blue, and also improves clarity. The eyes will become less strained, and this has a positive effect on performance.

Popular varieties

The right eyeglass purchase can help reduce eye strain and improve your quality of life. The frame is the last thing you pay attention to, the main thing is to deal with glass and optical characteristics. You can buy glasses yourself, but it is better to contact an optometrist who will conduct a thorough analysis and write out the only correct prescription. With this piece of paper, a person will go to the optician and in 5 minutes will find a suitable option, without overpaying.

Aspherical models are designed for people with a high degree of myopia. A distinctive feature of this design is its thickness and low weight. This allows the glass to fit into any frame for added convenience. Another advantage of this option is that the size of the eyes does not change, in contrast to analogs that have thick lenses.

With age, vision deteriorates both near and far. It becomes more difficult to see letters, faces or objects. Therefore, some people carry several glasses with them at once. For example, some for reading newspapers or books, and the second for driving. They are selected individually for each user.

It is not always convenient to carry 2-3 pairs with you, therefore we have developed progressive lenses. The advantage of the model is the division into near and far zones. Thanks to high-quality optical properties, the eyes can easily move from reading advertisements at a distance to answering SMS at close range.

Modern manufacturers offer hundreds of different models with unique frames and finishes. However, only an optometrist can choose the right option. Consultants in an optician salon will not be able to fully select glasses for each person if they do not have a special device for eye diagnostics.
