Wearing contact lenses can be an efficient and comfortable alternative to glasses. However, if you often find yourself struggling to identify whether your lens is inside out, it can lead to discomfort and potential eye issues. In this comprehensive guide, we will explore how to tell if a contact is inside out, the differences between inside out and outside in, and some useful tips for proper lens care and management.
Understanding Contact Lens Orientation
Before delving into the specifics of how to tell if a contact lens is inside out, it’s essential to understand how contacts are designed. Contacts are made to sit gently on the curvature of your eye. When fitting them, it’s crucial that they are placed correctly to ensure optimum vision and comfort.
The Basic Structure of a Contact Lens
Convex Outer Surface: This is the side that faces outward when worn. It is usually smoother and helps in maintaining the curvature to fit the eye better.
Concave Inner Surface: This side faces your eyeball. It has a different curvature and typically has a small weight to help it sit securely on the eye.
- Edge Design: Some lenses have specially designed edges to enhance comfort, which can be affected when the lens is inside out.
How to Tell If Your Contact Lens Is Inside Out
Identifying if your contact lens is inside out can be tricky at times, but here’s a reliable method to determine its orientation.
The "Bowl" Test
- Step 1: Place the lens on the tip of your finger.
- Step 2: Look at the lens from the side.
Step 3: Examine the shape:
- If the lens forms a perfect bowl shape and the edges are slightly higher than the center, it’s the correct orientation.
- If the lens flares out at the edges, resembling a more flattened dish, it’s likely inside out.
Visual Inspection
- Utilize Lighting: Hold the lens up to a light source. A correctly oriented lens will appear smooth and even throughout.
- Check for Small Indentations: Look carefully at the lens and check if the edges are raised or have any indentations. Generally, the inner surface will have a slightly different appearance.
The Finger Test
- Step 4: Gently pinch the lens between your thumb and index finger. If the lens forms a small cup and doesn’t flop over, it is positioned correctly. A disoriented lens will often flip or feel less stable during this test.
The Color and Texture Check
- Step 5: Some contact lenses have a tint or a pattern. When looking at the lens, observe whether the color is even and uniform. An inside-out lens might distort color or texture.
Common Symptoms of an Inside Out Contact Lens
Wearing a contact lens inside out can lead to uncomfortable symptoms. Here are some signs you might experience:
- Discomfort or Irritation: Constant urge to rub your eyes.
- Blurred Vision: The lens does not sit correctly, affecting your focus.
- Lens Movement: The lens moves excessively on your eye, making it uncomfortable.
- Increased Tear Production: Your eyes might react with excessive tears as they attempt to flush out the irritation.
Tips for Proper Contact Lens Handling
To avoid the confusion of inside-out lenses and to ensure a smoother contact lens experience, follow these best practices:
Maintain Clean Hands
- Always wash your hands thoroughly with soap before handling contact lenses to prevent contamination.
Use Proper Solution
- Keep your lenses in appropriate contact lens solution when not in use. Avoid using tap water or saliva as it can lead to infections.
Establish a Routine
- Develop a systematic method for inserting and removing your contact lenses. For instance, always start with the right eye so you will remember which lens goes where.
Label Your Cases
- If you wear different prescriptions or types of lenses, label your cases clearly to avoid mix-ups.
Regular Eye Checkups
- Schedule regular checkups with your eye care professional. This will help to ensure your prescription is accurate and your lenses are fitting properly.
What To Do If You Have Worn a Contact Lens Inside Out
If you realize that you’ve been wearing a contact lens inside out for a period, don’t panic. Here’s what you should do:
- Remove Your Contacts: Gently take the lens out of your eye.
- Clean the Lens: Rinse it with the appropriate contact lens solution.
- Recheck Orientation: Use the methods discussed above to ensure the lens is positioned correctly.
- Reinsert and Monitor: Once it’s in the correct position, pay close attention to how it feels and looks.
When to Seek Professional Help
If you consistently have difficulty determining if your lenses are inside out or if any symptoms persist—even after ensuring the lenses are oriented correctly—consider consulting an eye care professional. Below are specific scenarios when you should seek help:
- Severe Discomfort: Persistent pain or irritation that does not resolve.
- Signs of Infection: Symptoms such as redness, swelling, or discharge from the eye.
- Changes in Vision: Any sudden changes in your vision or seeing halos around lights.
