Hyperbaric Chamber Eye Safety: Can You Wear Contacts During a Session?
Hyperbaric Chamber Eye Safety: Can You Wear Contacts During a Session?
Table of Contents
If you run a wellness center or are setting up a hyperbaric chamber for home recovery, safety is always the top priority. A question that frequently pops up from users getting ready for their first session is: "Do I need to take my contacts out?"
The short answer? It depends on the type of lenses. Soft contact lenses are generally perfectly fine to wear, while hard contacts are an absolute no-go. Let’s dive into the "why" behind this rule and look at how modern recovery chambers are designed to keep users safe and comfortable.
The Physics of Pressure: Soft vs. Hard Contacts
To understand the rules, we have to look at simple physics—specifically, Boyle’s Law, which explains how gases expand and contract with changes in pressure.
Hard Contacts (RGP Lenses): Rigid gas-permeable (RGP) lenses hold their shape. When the hyperbaric chamber pressurizes and depressurizes, tiny air bubbles can get trapped between the hard lens and the cornea. Because the lens won't flex, these bubbles expand or shrink, which can cause intense eye pain or even a corneal abrasion. Always remove hard contacts before a session.
Soft Contacts: Soft lenses are porous and conform perfectly to the shape of the eye. They allow gases to pass through easily and don't trap air bubbles. For the vast majority of users, wearing soft contacts during a wellness session is completely safe.
Understanding Your Equipment: Ambient Air vs. Oxygen
The rules also make a lot more sense when you understand how modern non-clinical hyperbaric wellness equipment actually works.
In our 1.3 to 1.5 ATA portable soft-shell hyperbaric chambers, the setup utilizes dual air compressors alongside an oxygen concentrator. The chamber itself is pressurized with regular, ambient air. Users wear a standard oxygen mask to breathe in the concentrated oxygen and prevent nitrogen saturation. Because the environment inside the chamber is just compressed room air—and not 100% pure oxygen—the eyes are not directly exposed to high-oxygen environments. This makes wearing soft contacts incredibly safe.
For high-performance recovery facilities using 2.0 ATA hard-shell hyperbaric chamber, the pressure gradient is higher. While these non-clinical recovery units may utilize Built-in Breathing Systems (BIBS), the core rule remains: soft contacts are generally okay, but hard lenses must be removed to avoid any pressure-related issues.
Best Practices for Wellness Centers & Home Users
To ensure a smooth and relaxing experience, facility operators and home users should implement a quick pre-session checklist:
Ask the Question: Always ask users if they wear contacts and specifically what type.
Keep Lens Cases Handy: Keep spare, sterile contact lens cases and multi-purpose solution on hand for users who forget to take out their hard lenses.
Manage Dryness: The compressed air inside the chamber can get a bit dry. Even soft lens wearers might experience mild dryness, so having preservative-free artificial tears available post-session is a great touch.
Frequently Asked Questions (FAQ)
Can I wear regular reading glasses inside the chamber?
Yes! As long as your frames don't have sharp edges that could damage the interior of a soft-shell chamber, wearing standard glasses to read a book or watch a tablet is perfectly fine.
Do I need to worry about oxygen irritating my eyes?
Not in a wellness setup. Since you are breathing oxygen through a standard mask and the chamber is filled with compressed ambient air, your eyes are not taking a direct hit of pure oxygen.
Prioritizing safety ensures that every hyperbaric session delivers the ultimate relaxation and recovery benefits. If you're looking to upgrade your facility or home setup, explore our premium range of 1.3 ATA to 2.0 ATA wellness chambers today.
