If the lenses in your glasses have popped out, don't panic – you can usually put them back in. However, you need to be careful as inserting a lens incorrectly can cause it to break. Before attempting to reinsert a lens, check for any cracks, chips, or breaks in the lens or frame. If the lens is undamaged, you can try to refit it. One method is to place the frame in a bowl of warm water to soften the plastic, before removing it and pushing the lens in from the back, closest to the nosepiece. Another method is to insert the lens from the front, lining up the edge of the lens with the frame and clicking it into place.

What You'll Learn
Inspect lenses for any cracks, chips or breaks
Inspect the lenses for any cracks, chips or breaks. It is important to ensure that the lenses are not damaged before inserting them into a new frame, as they can break more easily if they are already compromised. Even small cracks or chips can become larger fractures when inserted into a new frame. This is because the process of inserting lenses into a frame requires some force and manipulation, which can cause existing cracks to spread or chips to become larger.
If the lenses are compromised in any way, they should not be inserted into a new frame. Instead, you should seek new lenses to avoid further damage or injury. It is also important to note that if there are any scratches on the lenses, they can also be magnified by the insertion process, so it is best to use lenses that are free of any marks or scratches.
To check for cracks, chips or breaks, hold the lens up to a light source and slowly rotate it, examining all areas of the lens for any signs of damage. If the crack, chip or break is small, it may be difficult to see with the naked eye, so using a magnifying glass or a microscope can help to identify any issues.
If you are unsure whether the lenses are damaged or not, it is best to err on the side of caution and assume that they are compromised. In this case, it is recommended to consult a professional optician or eyewear specialist who can advise on the best course of action and provide guidance on obtaining suitable replacement lenses.

Soften plastic frames with warm water
Softening plastic frames with warm water is a great way to make them more flexible and easier to work with when fitting in new lenses. Here is a step-by-step guide:
Prepare the Frames and Water
Firstly, identify if your frames have screws. If they do, use an eyeglass screwdriver to remove them by turning counter-clockwise. If your frames are held together by screws, you will need to separate the parts to effectively submerge the sections with lenses.
Next, prepare a bowl of warm water. Ensure the bowl is large enough to fully submerge the frames. The water should be warm, not boiling, as you do not want to melt or deform your frames. Microwaving the water is a quick way to get it to the right temperature.
Soak the Frames
Place the frames in the bowl, ensuring the lenses are face down, and fully immerse them in the water. Leave the frames in the water for around a minute. The warm water will heat up the plastic, making it softer and more pliable.
Dry and Re-Heat
After a minute, remove the frames from the water and gently shake off any excess liquid. Use a microfiber cloth to carefully dry the frames and lenses. If the frames begin to cool down and harden before you can insert the new lenses, simply repeat this step to re-heat and soften the plastic again.
Insert the Lenses
Now that the plastic is softened, it is time to insert the new lenses. With the frames warmed and dried, hold one lens to one eye, with the other eye closed, to determine the correct orientation and side of the lens. Push the lens into the correct side of the frame, starting with the side closest to the nose rest. Gently push the lens into place, moving towards the ear rest. You should hear a clicking or snapping sound when the lens is fully inserted.
Repeat this process for the second lens, ensuring the frames remain warm and pliable. Finally, allow the frames to cool completely before wearing them.
By softening plastic frames with warm water, you can easily fit new lenses and give your glasses a new lease of life!

Insert lenses from the front of the frames
To insert lenses into plastic frames from the front, you will first need to prepare the frames by softening the plastic. This can be done by heating the frames. Fill a microwave-safe container with water and heat it in the microwave for about a minute. The container should be large enough to fully submerge the frames. Place the frames in the warm water to soften the plastic and make them pliable.
Once the frames are pliable, remove them from the water and dry them. Now you can insert the lenses. Turn the frames towards you and line up the new lenses with the frame. You may need to heat the frames further to make them more flexible. Push and twist the lenses into the frame, inserting the lens arm first. You should hear a clicking sound as the lenses snap into place.
Do a safety test by running your fingers around the edge of the lens to ensure they are secure. If the lenses are not secure, repeat the process of heating the frames and inserting the lenses. Once the lenses are in place, clean them with a soft cloth.
It is important to note that you should always check your lenses for any cracks or chips before inserting them into a new frame. Lenses with cracks or chips are more likely to break during the insertion process.

Do a safety test by running fingers around the edge of the lens
When fitting lenses into plastic frames, it is important to do a safety test by running your fingers around the edge of the lens to ensure they are in place. This is done after inserting the lenses and hearing the clicking sound that indicates the lenses are in place.
To insert the lenses, turn your glasses towards you and line up the new lenses with the frame. Click them into place from the front of the frames. You should hear a clicking sound.
The safety test is an important step to ensure that the lenses are secure and will not fall out. It only takes a few seconds and can prevent the inconvenience and potential hazard of a lens falling out while you are wearing the glasses.
By running your fingers around the edge of the lens, you can feel for any gaps or irregularities that could indicate that the lens is not fully inserted or securely in place. A properly inserted lens should feel snug and secure, with no movement or wiggling when you run your finger along the edge.
If you feel any gaps or notice any movement, it may indicate that the lens is not fully inserted or is misaligned. In this case, you can try to adjust the lens by gently pushing or wiggling it into the correct position. It may be necessary to repeat the insertion process to ensure a secure fit.

Allow frames to cool before wearing
When fitting lenses into plastic frames, it is important to allow the frames to cool before wearing them. This is because the plastic needs to be heated to make it flexible for the insertion of lenses. Once the lenses are in place, the frames need to cool down and return to their original state so that they can hold the lenses securely.
To fit lenses into plastic frames, you will need to start by heating the frames. One method is to fill a microwaveable container with water and heat it in the microwave for about a minute. The container should be large enough to fully submerge the frames. Place the frames in the warm water to soften the plastic.
With the frames now pliable, you can begin the process of inserting the lenses. Line up the new lens with the frame, starting with the side closest to the arm. Push the lens into the frame, starting from the back, and work it into the nose area. You should hear a clicking sound, indicating that the lens is in place. Repeat this process for the second lens.
At this point, it is crucial to allow the frames to cool completely before wearing them. This ensures that the plastic hardens and secures the lenses in place. While the exact cooling time may vary depending on the type of plastic and the temperature of the water, it is generally best to wait for at least a few minutes. You can place the glasses on a flat surface to let them cool down uniformly.
Once the frames have cooled, you can perform a final check to ensure the lenses are secure. Run your fingers around the edge of each lens to confirm they are firmly in place. If the lenses pass the safety test, give them a quick clean with a soft cloth, and your glasses are ready to wear.
