China contact lenses

Types of China contact lenses

There are many types of contact lenses in China, with each being suited for a different purpose and with different preferences overall. Below are some of the most common types that are often found on the market.

Clear soft contact lenses

This is the most common type of contact lens. The clear soft contact lenses are made from a flexible, highly permeable plastic called hydrogel or silicone hydrogel. These lenses are easy to fit into the eye, and as a result, many people prefer using them. Soft contact lenses feel very comfortable since they retain water and provide a soft cushion on the eye surface. They also give clear vision and correct many kinds of vision problems. Some of the advantages of clear soft contact lenses include:

• Comfort: Clear soft contact lenses are comfortable to wear daily. They are made of flexible material that molds to the shape of the eye.
• Vision clarity: They give sharp, clear vision because they stay in place better when the eye moves.
• Convenience: Clear soft china contact lenses are preferred because they are easy to insert, remove, and care for.

Toroconic lenses

Toriconic lenses correct astigmatism, which is a common vision problem. These lenses have different powers in all the lens meridians. Because of this, they can give clear, sharp vision at every angle. They are often made of the same soft, hydrogel materials as regular contact lenses. However, toric lenses are a bit thicker and have special shapes like a donut or some weird design. The advantages of these lenses are:

• Combining correction: Toric lenses fix nearsightedness or farsightedness while correcting astigmatism. This makes them suitable for people with mixed vision problems.
• Stability: The lens rotates when the eye moves, but it returns to its original position quickly. This provides a consistently clear vision.

Multifocals

Like many other things in life, vision correction also becomes complicated as one ages. People over 40 develop presbyopia, which makes it hard to focus on near objects. Multifocal contact lenses are designed to help with this problem. These lenses have different power strengths for distance, intermediate, and near vision. This lets the eye focus at any distance. Multifocal lenses are very helpful to people who need different types of vision correction. Some benefits of multifocal lenses include:

• All-in-one solution: These lenses eliminate people from requiring bifocal or trifocal glasses.
• Natural sight: The multiple power gradients in these lenses allow a more natural focusing process. This enables smoother transitions between distances.

Special blurred vision contact lenses

Many people have the problem of seeing things clearly and straight. This is called myopia or nearsightedness. Special blurred vision contact lenses are designed to correct myopia. They are made of hard gas permeable plastic. These lenses give a sharp vision on the retina by forming a ring of light around the blur circle. This reduces the blur, the palm, and the distraction of annoying shadows. The advantages include:

• Reduced myopia progression: New studies suggest that special contact lenses may interfere with the natural elongation of the eyeball during childhood or adolescence.
• Clear vision: These lenses not only decrease the rate at which myopia may worsen but also allow sharper and clearer vision.

Designs of China contact lenses

Design and color variations of contact lenses are not really all about the vision correction aspect only. They also play a significant role in enhancing the eye's appearance and fulfilling specific ocular health requirements. Below are the different types of designs of contact lenses.

Scleral lenses

Scleral lenses are larger than most other contact lenses. They sit on the white part of the eye, also known as the sclera. They cover the cornea, which is the clear front part of the eye. Scleral lenses create a fluid-filled dome over the cornea. This provides a cushion for people with eye conditions that change the shape of the cornea. Some advantages include:

• Precise vision: Scleral lenses provide sharp and clear vision by creating a smooth optical surface over any irregular cornea.
• Comfort: You may think that larger lenses are more uncomfortable. However, that is not the case at all. Scleral lenses are very comfortable to wear. They are larger than standard lenses but offer more eye surface area for support.

Orthokeratology lenses

These are also known as Ortho-K lenses. These lenses are made to reshape the cornea. The cornea is the clear front covering of the eye. This new shape then retains like a gentle impression for some hours after the lens is removed. These lenses are worn overnight to temporarily flatten the cornea for nearsighted individuals. This way, after the lens is removed in the morning, glasses are not needed until the end of the day.

• Corneal reshaping: Ortho-K lenses are specially designed to reshape the cornea during sleep. This provides an elongated or modified corneal shape for better vision.
• Myopia control: These lenses slow down the progression of myopia in children mainly by reducing the eye elongation associated with increasing nearsightedness.

Prosthetic contact lenses

Prosthetic contact lenses are artificial replacements for people who have lost their eyesight due to disease or injury. They can be used to improve vision or merely to restore the eye's appearance. Advanced technology and materials make prosthetic contact lenses much more effective and comfortable than their predecessors. Some of the benefits include:

• Improving appearance: These lenses can be painted to match the other eye or corrected for missing or injured eye elements.
• Comfort: Prosthetic lenses are made of soft or gas-permeable materials to make them more comfortable.

Sun reflective contact lenses

Eye care professionals recommend that one should not spend long periods outdoors without protecting their eyes from UV rays. This is particularly true for the bright sunlight that is experienced at seashores, mountain areas, or even snowy regions. Standard sunglasses may not block enough glare in such situations. Sunlight reflective contact lenses can be very useful here. These lenses not only block harmful UV rays but also filter and reduce glare for clearer vision and improved comfort. They come in different tints and polarization levels depending on the light conditions and activities one engages in.

How to choose China contact lenses

When choosing contact lenses, people generally consider many factors. These include comfort, visual acuity, availability, and how to match the eyesight of the eyes. As such, people prefer the various kinds of contact lenses in China for different purposes. Below are some of the factors that influence these preferences.

Breathability

You will agree that the comfort of wearing contact lenses for long hours is a common priority consideration. Though individual preferences vary, general factors should make any variety of contact lenses appealing. Soft contact lenses made from hydrogel or silicone hydrogel materials tend to dominate the market since they are usually more comfortable.

Hydration

The hydration level of contact lenses is critical for keeping eyes healthy and comfortable. Lenses with higher water content provide more oxygen to the eye. This results in a feeling of comfort even after several hours of wear. However, high-water-content lenses can also be thinner and drier in a non-humid atmosphere. Fortunately, there are also many non-water-content lenses with extra moisture. They keep the eyes hydrated.

Replacement schedule

Another eye-catching feature of Chinese contact lenses is their replacement schedule. These are daily and extended wear lenses to cater to people's varying needs and lifestyles. The advent of disposable lenses has also made it easier to maintain good eye health.

Cost

It goes without saying that when making a purchasing decision, the associated costs are a highly considered factor. In the case of china lenses, the cost goes as a function of type, brand, and material. For instance, what one pays for prescription orthokeratology lenses or scleral lenses will not be the same as the amount charged for daily disposables.

Medical history

People with specific medical or ocular conditions have to be a little more careful when choosing contact lenses. People have different preferences when it comes to wearing lenses. Some people prefer gas-permeable lenses. Others settle for the comfort and ease of flexibility offered by soft contact lenses. That is also the case for those who require specialty contact lenses for keratoconus or other corneal diseases or for prosthetic purposes. They have to ensure that they find a qualified eye care specialist to help them choose and fit these contact lenses.

Quality and durability of China contact lenses

Good news for those using contact lenses. There are plenty of high-quality options available in China. The development of these has made them resistant to tearing, scratching, or warping. The new, advanced materials and technologies used in manufacturing these means that they can offer the required level of comfort and clarity for a substantial period.

Some common features of these contact lenses are that they are made from soft, flexible materials. They adhere closely to the eye's surface to provide a comfortable fit. The more premium ones, like the rigid gas permeable (RGP) or scleral lenses, tend to be more durable than their soft counterparts. That does not mean that they are better in any way. They generally offer better oxygen permeability andustum more longer.

The durability of contact lenses ranges with the type of lens chosen and individual eye care needs and preferences. One of the most durable varieties of contact lenses, the rigid gas-permeable lenses, is durable and long-lasting with proper care. They are also more resistant to deposits and require less frequent replacement than some of the softer disposable lenses.
