Problem: Cannot insert the lens to the eyes.

Solutions: This problem usually caused by either of the following.

Incorrectly opening the lid: The correct way to open the eyelid is to ensure it is wider than the iris, and you should not blink.
Properly opening the eyelid: If the eyelids are opened well, but your fingers become weak when inserting the lens, you may find it difficult to keep your eyes open. (Remember, if you do it correctly, you will not blink.)
Fear of inserting the lens: It’s normal to feel hesitant about inserting the lens into your eyes.
If you cannot resolve this problem: You can record a video of the lens insertion process and send it to Line @drbirdcl so Dr. Bird can provide you with the correct advice.

Problem: Insert the lens that move to sclera (white part of the eye).

Solutions: This problem usually caused by either of the following.

When inserting the lens into the center of the eye or cornea, your eye may move away from the lens, causing misalignment. To solve this problem, open both eyes and look at your reflection in the mirror. This will help minimize eye movement away from the lens.
Do not forget to look down while gently closing your eyes after inserting the lens. This allows the upper lid to press the contact lens against the bottom part of the white of your eye. The easiest way to resolve this issue is to look down while gently closing your eyes after insertion.

Problem: Can not see clearly.

Solutions: This problem usually caused by either of the following.

Slight bubbles under the lens after insertion (most common). If you notice them, you should remove and reinsert the lens. You can also solve this problem by putting artificial tears or normal saline into the lens. Place a mirror flat on the table and bend your upper body and neck so that your face is parallel to the table. While keeping your head in this position, try to look down at your chin before inserting the lens.
Dirty lens with protein deposits. You can solve this problem by cleaning the lens with a protein cleaner, such as Progent, at least every three months.
Contact lens inserted on the wrong side. You can resolve this issue by checking the lens before insertion. If you forget the correct side of the lenses, just call Dr. Bird.

Problem: Eye pain & Red eyes.

Solutions: This problem usually caused by either of the following.

Debris or foreign bodies are significant problems, especially if they are under the lens. The patient will experience immediate eye irritation and soreness. You can solve this problem by removing the lens, washing it out, and then reinserting it.
If you notice that your lens is damaged, chipped, cracked, or broken after removal, do not insert it into your eyes. This may cause eye injuries. Instead, call a doctor or optometrist to order a new one.
Allergic reactions to preservatives in contact lens solutions. Solutions that are not effervescent typically contain preservatives, which may cause discomfort for some people when inserting lenses. You can solve this problem by rinsing the lens with normal saline before insertion to remove the preservative. Caution: Normal saline should be discarded 14 days after opening, as it is preservative-free. Using normal saline for an extended period may cause bacteria to grow in the bottle. Do not soak the lens in normal saline, as it contains no preservatives. Be careful that the tip of the bottle does not touch anything else, as this can introduce germs into the bottle.
Unclean hands can introduce soap or foreign substances into the eyes.
Taking too long to insert the lens can cause it to dry out, leading to discomfort after insertion. You can alleviate this problem by closing your eyes for a few minutes after insertion, which will help. To prevent this issue, you should practice lens insertion.
Keeping your eyes open for too long can cause dryness. To prevent this problem, you should practice lens insertion regularly.

Problem: Eye irritate after inserted the lens.

Solutions: This problem usually caused by either of the following.

As a new user who is just beginning to use RGP lenses (or who has not worn RGP lenses for a long time), you may feel discomfort in the first few days of use. The eyes are usually most uncomfortable on the first day, but this discomfort will gradually decrease until you feel almost nothing after wearing the lenses for 4-7 days. If your eyes are irritated too much on the first day (or during the first few days), you need to close your eyes as soon as you insert the lenses. Eye irritation typically occurs when you blink, so you may feel no discomfort when your eyes are closed.
If your hands are not clean, dirt can stick to the contact lens. When you insert it into your eye, this can cause eye irritation. Be sure to wash your hands thoroughly before lens insertion and use a paper towel (kitchen towel) to reduce dust from attaching to your hands.
If the lens is out of the eye center, you can move it to the center or remove and then reinsert it.
If there is dust under the lens, remove it, wash it out, and then reinsert it. If irritation persists, remove the contact lenses and call a doctor or optometrist.
After removing the lens, if you notice that it is damaged, chipped, cracked, or broken, do not insert it into your eyes. Doing so may cause eye injuries. Instead, call a doctor or optometrist to order a new lens.
If you experience slight eye irritation symptoms that occur frequently or almost every time after wearing the lenses, using a lubricant solution before insertion can help provide more comfort.

Problem: Temporary discomfort of insertion.

Solutions: This problem usually caused by either of the following.

Soak the lenses in an effervescent solution or hydrogen peroxide (such as Clean Care, etc.) for less than 6 hours. If you experience irritation, remove the contact lenses and rinse all residue from the bottle of normal saline. Symptoms of eye irritation may still persist, but they should improve. If you experience excessive eye irritation while blinking, just close your eyes. If the symptoms do not improve after 4 hours, you should see a doctor (usually, the symptoms are mild and will improve rapidly after 1-2 hours of rinsing).
Allergic reactions to preservatives in contact lens solutions can occur. Solutions that are not effervescent usually contain preservatives, which may cause some people discomfort when inserting lenses. To alleviate this problem, rinse the lens with normal saline before insertion to remove the preservatives. (Caution: Opened normal saline should be discarded after 14 days because it is preservative-free. Prolonged use may lead to bacterial growth in the bottle. Do not soak the lenses in normal saline, as it does not contain preservatives. Be careful that the tip of the bottle does not touch anything else, as this can introduce germs into the normal saline.)
Ensure your hands are clean. Soap or foreign substances can enter your eyes.
Taking too long to insert the lenses can lead to discomfort due to drying. To address this issue, close your eyes for a few minutes after insertion to help alleviate discomfort. To prevent this problem, practice inserting the lenses.
Keeping your eyes open for too long can cause dryness. To prevent this issue, practice the insertion process regularly.
