What Are the Symptoms of an Inside-Out Contact Lens?

Recognizing the symptoms of an inside-out contact lens can help you quickly correct the issue and avoid discomfort. Here are some common signs to look out for:

Discomfort and Gritty Feeling

One of the first signs that your contact lens might be inside out is a feeling of discomfort or a gritty sensation in your eye. This happens because the lens isn't sitting properly on your eye's surface, causing irritation.

Excessive Movement of the Lens 

If your contact lens moves around too much when you blink or seems to shift out of place, it might be inside out. A properly oriented lens should stay relatively stable on your eye.

Watery Eyes and Lens Popping Out

Another indication is excessively watery eyes or if the lens pops out unexpectedly. When the lens is inside out, it doesn't conform to the shape of your eye as it should, leading to these issues.

Being aware of these symptoms can help you identify and fix an inside-out lens promptly, ensuring a comfortable and clear vision experience.

Before exploring ways to check if contact lenses are inside out, if you are new to contact lenses, here is our detailed guide with practical tips for beginner contact lens wearers.

Ways to Check Inside Out Contact Lenses

Here are some easy ways to check whether your contact lenses are inside out:

Cup or Bowl Method

The Cup or Bowl method is a simple and effective way to check if your contact lens is inside out. Here are the steps to identify the correct shape:

1. Place the Lens on Your Fingertip: Put the contact lens on the tip of your finger, with the edge facing up.
2. Hold It Up to Eye Level: Lift your finger to eye level so you can view the lens from the side.
3. Check the Shape: If the lens is correctly oriented, it will look like a small cup, with edges pointing straight up. If it is inside out, it will resemble a rimmed bowl, with edges flaring outward.

The Taco Test

Another reliable method for checking the orientation of your contact lens is the Taco Test. Here’s how to perform it and interpret the results:

1. Hold the Lens Between Your Thumb and Index Finger: Position the lens with its center between your thumb and index finger.
2. Gently Squeeze the Lens: Lightly press the lens as though you were going to fold it in half. Be gentle to avoid damaging the lens.
3. Observe the Edges: Look at the edges of the lens while squeezing it.
• If the edges point upward, forming a shape similar to a hard-shell taco, the lens is right side in.
• If the edges flare outward towards your fingers, the lens is inside out.

Using Laser Markings (1-2-3 Method)

Some contact lenses come with laser markings to help you determine if they are inside out. Here’s how to identify and interpret these markings:

1. Place the Lens on Your Fingertip: Position the contact lens on the tip of your finger.
2. Hold the Lens Up to Eye Level: Raise your finger to eye level and look closely at the lens.
3. Inspect for Laser Markings: Rotate the lens if necessary to find the markings. These might include numbers or letters, such as “123.”
4. Interpret the Markings:
• If the numbers or letters appear correctly oriented, the lens is right side in.
• If the markings appear backward, the lens is inside out.

Checking for Tinted Edges

Many contact lenses have a slight tint around the edges to help you identify their orientation. Follow these steps to use this feature:

1. Place the Lens on Your Fingertip: Position the contact lens on your finger with the edge facing up.
2. Look Down at the Contact’s Edges: View the lens from above, focusing on the edges.
3. Assess the Tint:
• If the edges look brightly tinted (usually blue or green), the lens is correctly oriented.
• If the tint appears pale or you can’t see it, the lens is likely inside out. Flip the lens and check again to confirm.

Easy Flip Test

The Easy Flip Test helps you determine the lens orientation by how easily it flips. Here are the steps:

1. Hold the Lens in Your Palm: Place the contact lens in the palm of your hand.
2. Try to Flip the Lens: With your other hand, gently attempt to invert the lens.
3. Interpret the Ease of Flipping:
• If the lens flips easily, it is inside out.
• If the lens resists flipping and maintains its shape, it is correctly oriented.

Using these additional indicators can further ensure that your contact lenses are properly oriented before you insert them, enhancing comfort and vision clarity.

Practical Tips for Daily Use

Developing a habit of checking your contact lenses before insertion is essential for ensuring comfort and clear vision. Here are some practical tips:

• Daily Checks: Make it a routine to inspect your lenses each day before putting them in. This will help you become more familiar with their correct orientation and reduce the likelihood of inserting them inside out.
• Consistent Practice: Over time, you will become more adept at recognizing the correct lens orientation quickly and effortlessly.

Tips for New Contact Lens Wearers

If you are new to wearing contact lenses, these tips can help you adjust and become proficient:

• Take Your Time: Don’t rush the process of inserting your lenses. Give yourself enough time to inspect and place them correctly.
• Use Good Lighting: Ensure you are in a well-lit area to see the lenses clearly when inspecting them for orientation.
• Stay Calm: If you are having trouble, take a deep breath and try again. It can take a little practice to get the hang of it, but you will improve with time.

Orientation of Daily Contact Lenses in Packaging

Daily contact lenses are typically oriented correctly in their packaging. Here’s how to use this to your advantage:

1. Inspect the Packaging: When you open a new package of daily contact lenses, notice how the lens is positioned.
2. Keep the Same Orientation: As you remove the lens from the packaging, try to maintain its orientation. This will help ensure that you are inserting it correctly.
3. Minimal Handling: By minimizing the handling of the lens, you reduce the chances of flipping it inside out.

By following these practical tips and developing a routine, you can ensure that your contact lenses are always inserted correctly, providing you with comfortable and clear vision throughout the day.
