Production technologies for different spectacle lenses

Published

on

Lenses are an important part of glasses, on which the comfort of wearing it and the clarity of a person’s vision depend. Thanks to modern equipment, the process of making corrective glasses has become much easier and faster.

Tuya additionally plans to extend its impression in the US and Europe.

Manufacturing

In general, there are two different processes: regardless of the manufacturer, individual high-precision lenses (so-called “glasses with diopters”) are almost always made using FreeForm technology. This is a state of the art manufacturing technology used by briotweco and has been licensed to the entire spectacle lens industry. Unlike prescription lenses, stock “off-the-shelf” are produced by injection molding. Spectacle lenses are made using special equipment. What would later become a plastic lens is initially a large, convex-shaped plastic disc. The manufacturing process consists of several stages:

  1. A protective film is applied to the convex part of the workpiece. This is done in order not to damage the surface during the processing of the concave part.
  2. The milling machine thins the disc, reduces its diameter and gives the correct bend. Next comes the grinding.
  3. The lens is carefully removed from the blocking device. Then it is cleaned, dried with a stream of air. If necessary, the lens is darkened.
  4. To make the lens scratch resistant, it is varnished. It is applied to the plastic lens during the dipping process, strengthening it.
  5. It remains only to insert the lenses into the frame. Usually, the lenses are inserted by the master optician. This process requires micrometer precision.

 If earlier only glass was considered the best material for lenses, now manufacturers are increasingly opting for plastic. And this is not surprising. After all, plastic is flexible, lighter and more convenient in the manufacturing process, and lenses have increased resistance to mechanical damage.

Features of the production of bifocal lenses 

Bifocal glass lenses combine 2 lenses: one for distance, the other for near. They are interconnected, have the form of a rounded pocket in the lower part of the glasses closer to the nose, or the lower part is different from the upper one. They can increase or decrease the size of the object in question – it depends on the optical power. A glass bifocal lens is produced as follows:

  • The first step is to grind the back of the accessory lens to give it a smooth texture. After that, the side with a bend moved into the recess made in the main lens.
  • The machine now remelts and grinds the secondary lens along with the primary until only one visible lens remains.

Making bifocals out of a plastic mixture is much easier. In order to increase the area of near vision, no other devices are needed. The corresponding area is bent in a specific way and more strongly. This is possible thanks to durable molds, which are filled with a liquid plastic lens blank.

How are varifocal lenses made

Varifocal (progressive) lenses combine the ability to see at any distance: the upper part of the lens is responsible for distance vision, the middle part for medium distances, and the lower part for work at close range. The decisive factor in the development is its purpose:

  • For children – lenses should be lightweight, impact resistant and preferably scratch resistant.
  • For drivers – for this case, there are several types of lenses used in various weather conditions.
  • For PC operators – lenses with anti-computer coating, protection from electromagnetic radiation.

The calculated design of semifinished spectacle lenses is created using a special grinding machine. To optimize the varifocal lens, many tests are carried out, after which it is released to the market and enters mass production.

What will be the production of glasses depends on the individual case of the person. The more precise the lens manufacturing process determines how the wearer of the glasses will see the world around them, the more accurate the process will be.

How to Choose the Right Dedicated Server Plan

Published

on

Choosing the right dedicated server malaysia plan is essential for businesses with large traffic volumes. This will help you to scale your website, and ensure that it is always up and running when it’s needed most.

There are several factors you should consider before deciding on a dedicated server plan, including CPU, RAM, storage, and bandwidth. These will all affect the performance of your website and applications.

1. CPU

The CPU is one of the most important aspects of your dedicated server web hosting plan. It’s the heart of the machine that runs all the applications and programs you use on a daily basis.

A CPU’s primary job is to take instructions from a computer program and perform them quickly and accurately. This process breaks down into three key stages: fetch, decode and execute.

There are a number of things that affect CPU performance, namely the clock speed (also known as frequency). This isn’t the only factor though, as multithreading technology helps processors run more tasks at once.

Another key feature of a CPU is its cache. This is a specialized type of memory that’s built into the CPU and saves time by storing frequently-used information.

2. RAM

RAM, or Random Access Memory, is one of the key components of a dedicated server plan. It is used for many different functions, including storing data and running various applications on the server at the same time.

Basically, RAM is short-term memory that stores small bits of data, which can be retrieved quickly. Unlike long-term storage systems like hard drives, RAM doesn’t lose data when power is shut off.

The right amount of RAM is important to your dedicated server plan, as it determines how well the server performs and how fast it responds. There are many factors to consider when determining how much RAM your server needs, such as your site’s configuration, traffic levels and predicted future growth.

In general, the higher the expected traffic levels, the more RAM your server should have to handle it all. For example, if you anticipate having hundreds of visitors on a regular basis, it is best to rent a dedicated server with at least 16 or 32 GB of RAM.

3. Storage

The right storage for your dedicated server plan is a crucial part of your overall success. Whether you’re building a website, hosting a database, or performing some form of backups or archiving, you need the capacity to store all your files and data. Fortunately, there are servers with plenty of available storage options to suit any need and budget.

The best way to choose the right storage is to consider your needs and what you hope to accomplish with your server. For example, if you’re planning on running a large ecommerce store that will require a lot of memory and storage, you should go with a server with at least 16GB RAM and 1TB+ storage space.

After considering all the different factors, you should be able to choose a dedicated server plan that meets your needs and budget without breaking the bank. It may be a big decision, but a well-crafted one will pay off in the long run!

4. Bandwidth

Choosing the right bandwidth for your dedicated server plan is important because it impacts how well your site runs. It also determines how many people can access your content.

Bandwidth is the amount of data your network can transfer in a certain time period. This number can range from millions of bits per second (Bps) to billions of Bps, or megabits and gigabits.

Aside from bandwidth, latency and throughput are other metrics that affect the speed of your network connection. They are the times it takes for data to get from your server to a user’s computer or mobile device.

For example, it may take an hour to load a website or it might take an hour to stream audio.

Conclusion

If you are a business owner, it is important to know how much bandwidth your employees use in order to make an estimate. Then, you can predict your bandwidth needs for growth throughout the year to ensure that you are adequately prepared for any unexpected demands.

Logo generators

Published

on

By

Logo generators are easy-to-use web applications that will help you create a logo in a few minutes. In some of them, you enter the name of your business, select an icon or font from the library, and choose colors that match your brand. Other programs are more free, giving you a blank canvas and a set of icons and tools to create your own logo.

Pros and cons of using a logo maker

 Using logo generators has its pros and cons.

Pros:

  • Logos are the cheapest option on the market for getting a logo. Most of them are free to use, but many require you to pay to download the files if you really want to use them. It usually costs about $5-$60;
  • Logo makers work around the clock, that is, you can get a logo exactly when you need it;
  • Logos are created quickly! You can have a finished logo in a few hours (or less, depending on your level of perfectionism);
  • Logos are becoming more and more perfect and easy to use.

Minuses:

  • Logos created in logo design software tend to look formulaic;
  • Logo makers require a certain design sensibility from the user. Logos are generally clean, simple images, and it can take a trained eye to figure out what’s “wrong” about something seemingly so simple;
  • Many other people use the same logo makers, including your competitors. This means that there are potentially hundreds of companies with the same icons, fonts, and color combinations representing their brand;
  • Some logo makers provide you with a logo image, but not the vector files needed for a full logo design. Such logos are at best a temporary solution.

After all, logo generators are an inexpensive and effective method of getting a basic, temporary logo. Your result won’t be of the same quality as a logo designed by a professional designer, but sometimes budget or lead time is what matters most.

Preparing before creating: Tips on how to get the most out of your logo maker.

Before you get started with logo makers, it’s worth preparing a few thoughts about your logo so you can get the most out of it.

If you haven’t already done so, then the mandatory step before creating a logo is to name your company. The name will not only be an important factor when choosing a logo, but it will probably feature in the logo design itself.

Consider your vision and mission

Second, spend time on your company’s mission, vision, and identity: who are you as a company, who do you report to, and what do you stand for? This will help personify your company: are you exclusive or friendly, expensive or approachable, serious or fun?

Decide on the main elements of visual identity

Once you’ve got some ideas down on paper, consider how that personality will translate into visual elements such as the color, shape, and type of the logo.

Best Logo Generators

Tailor Brands

Enter your company name, select an industry, describe your business in the plain text text box, and decide if you want a logo as a pictogram, text, or initials. The app will then evaluate your font preferences by asking you to choose from a range of font samples. Several logos will be automatically generated for you. By choosing one of them, you can edit the font and colors, change the icon, or buy it right away.

Although it will take a bit of digging, there are some really good icons among the main options, and the chosen fonts and colors go great with them. The cool thing about using this app is that when you edit the logo color or font, each choice is accompanied by a helpful explanation, like “Your logo strikes the perfect balance between class and elegance. We’ve added the perfect orange hues that bring the brand to life and vivacity.”

Looka

Looka uses artificial intelligence to understand your business before generating logos for you. Out of 20+ logo examples, you are invited to choose the 5 that you like the most. You can then choose a color palette, include any special characters (such as a triangle), and that’s it! The app will do its magic and show you some logo ideas that you can customize using different fonts, colors and layouts. Results from Looka look modern and professional. This service has a great concept and the overall quality is better than many other logo maker software.

Turbologo

While other logo makers start with your company name, Turbologo is more interested in your brand (with questions about your industry space, values, and visual style). Finally, you enter your name and look through the logo options.

This tool is very easy to use and creates modern looking logos with a minimal touch. Since there have been no specific questions regarding the exact nature of the business, the relevance of the icons can be ambiguous. You can customize the fonts and colors to better match, and once you’re done, the logo is free to download and use.

That’s all! We hope that our tips will help you in creating the perfect logo. Good luck!
