Early Handcrafted Lenses
The first contact lenses were made by hand. These glass lenses covered the whole cornea. But, they were hard to wear for a long time because they were stiff and didn’t let much oxygen in.
Even though these handcrafted lenses started something new, they were very different from today’s lenses.
Introduction of Plastics and Polymers
In the mid-20th century, plastics and polymers changed contact lens fabrication. In 1939, Wichterle and Lím made a big leap with the hydrogel material. Hydrogels are polymers that absorb water, making lenses more flexible and comfy.
This led to the creation of soft contact lenses. These lenses were a hit because they were easier to wear.
Lathe-Cutting Technique
The lathe-cutting technique helped make contact lenses on a large scale. This method used lathes to shape and polish plastic or polymer into the right shape. Lathe-cut lenses were more comfortable and worked better than handcrafted lenses. This made more people use contact lenses for vision problems.
Spin-Casting Technique
The spin-casting technique, also known as molding, came after lathe-cutting. It poured liquid polymer into a mold and spun it fast to shape the lens. After curing, the polymer turned into a solid lens. Spin-casting made making lenses faster and more consistent, helping more people get contact lenses.
| Fabrication Technique | Key Characteristics |
|---|---|
| Handcrafted Glass Lenses | – Rigid and uncomfortable – Limited oxygen permeability |
| Hydrogel Lenses | – Improved flexibility and comfort – Enhanced wearability |
| Lathe-Cutting Technique | – Enabled mass production – Improved comfort and optical properties |
| Spin-Casting Technique | – Faster production – Greater consistency in lens design |
The story of contact lens fabrication is amazing. It started with handcrafted glass lenses and has moved to today’s comfy, breathable lenses. Thanks to new materials like plastics, polymers, and the injection molding process step by step, the industry keeps improving to meet our vision needs.
Injection Molding Optical Lenses – Introductionof GP Lenses
In the 1970s, GP (gas permeable) contact lenses changed the game. They were made from tough, precise materials that let more oxygen in. This was key for eye health and avoiding corneal hypoxia. Making GP lenses required careful machining and polishing for top-notch vision and durability.
GP lenses were a big deal in contact lens history. They used rigid materials to offer clear vision and protect eye health. This led to more lens design improvements and the use of new materials in contact lenses.
Now, GP lenses are still key in making quality lenses, even for smartphones. As tech gets better, the mix of lens making and new materials keeps changing the contact lens industry.
“The introduction of GP lenses marked a significant milestone in the evolution of contact lens fabrication, paving the way for further innovations in lens design and the integration of advanced materials.”
Advancements in lens design
The injection molding process step by step has changed a lot over time. So has the design of optical lenses made this way. The contact lens design field has seen big improvements. Now, there are advanced lens shapes for different eye needs.
Customized and Specialty Lenses
New tech like computer-aided design and 3D printing has changed how we make optical lenses. These tools let us make customized lenses that fit each person’s eyes and needs. This means a better fit and clearer vision for everyone.
There are also specialty lenses for specific eye problems. Aspheric lenses help with blurry vision in the dark. Toric lenses fix astigmatism. And multifocal lenses help with different distances.
| Lens Type | Key Features | Applications |
|---|---|---|
| Aspheric Lenses | Reduced aberrations, improved visual acuity | Low-light conditions, night driving, sports eyewear |
| Toric Lenses | Correction of astigmatism | Eyeglasses, contact lenses |
| Multifocal Lenses | Multiple focal points for near, intermediate, and distance vision | Presbyopia, bifocals, progressive lenses |
These changes in injection molding process step by step and contact lens design have made eyesight better. They’ve also given more options to people. THY Precision leads in these advances, always finding new ways to design and make lenses.
Integration of advanced materials
The injection molding process step by step has changed how we make optical lenses, especially for smartphones. It’s brought in new contact lens materials that make lenses more comfortable, safe, and work better.
In the late 1990s, silicone hydrogel lenses came out. They mix silicone and hydrogel to let more oxygen in and lower the risk of eye problems. This is a big deal for eye health.
- Silicone hydrogel lenses offer improved breathability and comfort for extended wear.
- The integration of silicone and hydrogel materials has been a game-changer in the contact lens industry.
Then, hybrid lenses showed up, changing lens design even more. They have a tough center and a soft edge. This gives clear vision and feels great.
“The combination of rigid and soft materials in hybrid lenses has revolutionized the way we think about contact lens design.”
New biocompatible materials and gas-permeable materials have made contact lenses better to wear and safer. These new materials let us make lenses for different people’s needs.
Putting these advanced materials together with the injection molding process step by step has changed the contact lens world. Now, lenses are more comfortable, give better vision, and are safer for users.
Injection Molding Optical Lenses process step by step
The injection molding process is key in making smartphone lenses. It makes sure the lenses are high-quality and precise. This is vital for great camera performance. Let’s look at each step of the process and see how they make the final product.
The Clamping Unit: Securing the Mold
The first step is the clamping unit. It keeps the mold closed during the process. This is crucial for making lenses of the highest quality.
The Injection Unit: Melting and Delivering the Plastic
Next, the injection unit melts the plastic and puts it into the mold. It has a hopper, screw, and heated barrel. These work together to make the plastic ready and send it to the mold.
Plasticizing: Ensuring a Consistent Melt
At this stage, the plastic is melted and mixed. A screw in a heated barrel makes sure the plastic is the right temperature and consistency. This is important for a good melt.
Melt Delivery: Filling the Mold Cavity
Then, the melted plastic goes into the mold through a special system. This step is key to making sure the lens has all the details it needs.
Part Ejection: Safely Removing the Molded Lens
After the plastic sets, the lens is taken out of the mold. This is done carefully to avoid damaging the lens.
Post-Mold Cooling: Maintaining Precision
The last step is cooling the lens. This lets it set and keeps it precise. It’s important for the lens to work well in smartphone cameras.
| Step | Description |
|---|---|
| Clamping Unit | Holds the mold in place and applies the necessary force to keep it closed during the injection and cooling stages. |
| Injection Unit | Melts the plastic material and injects it into the mold. |
| Plasticizing | Involves the melting and homogenization of the plastic material to ensure a consistent melt. |
| Melt Delivery | Distributes the melted plastic material evenly throughout the mold cavity. |
