Open contact

Open contact

Open contact refers to a type of contact lens that allows for increased oxygen permeability to the cornea compared to traditional contact lenses. This design aims to improve eye health and comfort for the wearer by reducing the risk of hypoxia and other complications associated with low oxygen transmission.

Design and Material

Open contact lenses are typically made from advanced silicone hydrogel materials, which have higher oxygen permeability than conventional hydrogel lenses. The design of these lenses often includes features such as:

• Increased water content
• Enhanced wetting agents
• Specialized surface treatments

Benefits

The primary benefits of open contact lenses include:

• Improved corneal health due to higher oxygen transmission
• Reduced risk of dry eye syndrome
• Enhanced comfort for extended wear
• Lower incidence of contact lens-related complications

Usage

Open contact lenses are suitable for a variety of wearers, including those with:

• Myopia
• Hyperopia
• Astigmatism
• Presbyopia

They are particularly beneficial for individuals who wear contact lenses for extended periods or have a history of contact lens-related issues.

Care and Maintenance

Proper care and maintenance of open contact lenses are crucial to ensure their longevity and effectiveness. This includes:

• Regular cleaning with appropriate contact lens solution
• Adhering to recommended replacement schedules
• Avoiding overnight wear unless specified by the manufacturer
