There are different types of contact lenses on the market. In fact, it is believed that some spectacles are capable of treating eye diseases in addition to poor eyesight. Therefore, it is important to understand the advantages and disadvantages of these latest tools. Modern contacts are made of soft lenses that are made of rigid types of water-based plastics and gases. They can be grouped according to the wear schedule.
Hard plastic material.
Contact lenses are made of hard plastic which is the same plastic material used to make translucent acrylic plastics. However, hard glasses do not have the capacity to absorb water to help oxygen pass through the lens and into the cornea. Wearing hard glasses can cause a lot of softness and discomfort because the eye requires oxygen to stay healthy and fit. The positive side of these glasses is their cleanliness because they are not easily infected by bacteria.
Soft-touch
Soft contact lenses are more flexible and easier to wear than hard lenses. They are made of soft plastic that is hydrophilic and has the ability to absorb water. Oxygen can be transferred to the eye which makes the lens satisfactory and more comfortable to wear. When a large amount of oxygen reaches the eyes, it indicates that you can wear soft contact lenses for a longer period of time, which is less likely to cause irritation. Although contact lenses are relatively safe, they can cause little issues such as discomfort, pinkness or tearing. In some cases, too long lenses can cause infections such as corneal ulcers that can cause permanent harm to vision.
