Installing lenses in plastic frames can be a tricky process. While it is possible to do it yourself, it is recommended that you take your glasses to an optician to avoid the risk of damaging your frames or lenses. If you choose to install the lenses yourself, you will need to ensure that your frames are the same size as the lenses. You may need to heat the frames to make them more flexible, but be careful not to melt the plastic. Once the frames are pliable, insert the lenses on the temple side of the eyewire, pressing them into the bevel with your thumbs. Work quickly so that the frames do not cool down, and be careful not to use too much force, as this could damage your frames.

Removing old lenses from plastic frames
Firstly, identify if your lenses are held in place by a screw. If they are, use an eyeglass screwdriver to carefully loosen and remove the screw by turning it in a counterclockwise direction. Place a towel on your work surface to prevent the small screw from rolling away and becoming lost. Once the screw is removed, you are ready to move on to the next step.
If your lenses do not have a screw, you will need to heat the frames to loosen the plastic. You can do this by filling a bowl with very hot water and completely submerging the frames for about a minute. Alternatively, you can use a hairdryer on a medium heat setting, holding it about 6 inches away from the frames for around 5 minutes. Be careful not to get the frames too hot, as this could damage them.
Once the frames are heated, dry them off with a microfiber cloth. This will also help you get a better grip on the frames and lenses. Now, hold the frame with one hand, and with the other hand, place your thumb on the concave side of the lens, just under the bridge of the nose. Gently push the lens inward until you feel it pop out of its groove. Repeat this process for the other lens.
It is important to note that removing lenses from plastic frames can be delicate work, and you may still break your glasses or lenses even when following these steps carefully. If you are unsure or uncomfortable with any part of the process, it is best to leave it to the professionals and take your glasses to an optician for lens removal and replacement.

Heating the plastic frames
If you want to replace the lenses in your plastic frames, you may need to heat the frames to loosen the plastic and remove the old lenses. It is important to be cautious when heating the frames as plastic can go from bendable to melted very quickly.
There are a few different methods you can use to heat the plastic frames. One way is to use a hairdryer. Hold the hairdryer about 6 inches (15 cm) from the frames and turn it on to a medium heat and speed setting. Move the dryer around the frames near the lenses for around 5 minutes until they are more flexible. Be careful not to use a high heat setting as this may melt or deform your frames.
Another method is to place the glasses in a bowl of hot water. Set the glasses in the bowl so that the concave sides of the lenses are facing up. Leave the frames in the water for about 1 minute to heat the plastic and make it easier to bend. After 1 minute, dry the lenses and frames with a microfiber cloth so that they do not slip.
You can also try placing the frames in a bead pan with glass beads. Set the heat on the beads to the lowest setting that will allow you to achieve pliability. Once the frames are pliable, remove them from the bead pan and insert the lenses.
When heating the frames, concentrate the heat on the eyewire portions, avoiding the end pieces and bridge areas. Only heat the portion that needs to be heated, and work quickly so that the frame doesn't cool down.

Inserting new lenses
Firstly, ensure that your frames are suitable for lens replacement. Your optician will be able to assess this for you. It is also important to make sure that your frames are clean and free of any residue. You can use an eyeglass cleaner or a solution of warm water and dish soap to clean your frames.
If your frames have screws, you will need to remove these with a specialised eyeglass lens removal tool or a pair of tweezers. Place a towel on the floor to catch any screws that are dropped or dislodged. Once the screws are removed, gently pull the frames apart until the lens can be removed.
If your frames do not have screws, you will need to use heat to remove the lenses. You can do this by filling a basin with boiling water and immersing the frames for around a minute. If the lenses do not come out, you can try using a hairdryer to heat the frames. Once the frames are malleable, gently press the lenses out with your fingertips.
Insert your new lenses while the frames are still warm and flexible. Line up the edge of the lens with the frame, inserting the lens from the front, arm side first. You should hear a clicking sound when the lens is in place.
Finally, run your fingers around the edge of the lens to ensure that it is secure.

Cleaning the frames
When installing new lenses, it is important that the eyewear is clean. You can use an eyeglass cleaner or a solution of water and dish soap with warm water. Get your hands wet before touching the lens surface so as not to leave fingerprints on it. Remove any dirt or debris with a lint-free cloth. You can also submerge the frames in the solution and gently shake them to remove any dirt or particles that may be on the lenses.
If you are reusing old lenses, ensure they are in good condition, with no scrapes, scratches, or cracks. Clean the lenses with a new cloth before installing them into the frames.
If your frames are one-piece plastic and don't have screws, you will need to use heat to remove the old lenses. Fill a basin halfway with boiling water and immerse the frames in the water for about a minute. When the frames are malleable, gently press one lens out at a time using your fingertips. You can also use a hairdryer to heat the frames.
Once the frames are warm and flexible, insert your new lenses. If your frames require heat, be mindful that plastic can go from bendable to melted within seconds. Heat the frames until they are pliable, and be careful not to overheat and risk melting the plastic. Work quickly so the frames don't cool down.
Finally, do a safety test by running your fingers around the edge of the lens to ensure they are in place.

When to take to a professional
While there are safe ways to put a lens back into plastic frames yourself, it may be better to take your glasses to an optician rather than attempt a DIY fix at home. Opticians have access to special tools and instruments designed specifically for working with eyeglass lenses and frames. They will also know how to handle your glasses with care, avoiding applying too much pressure or heat, which can cause damage to the frame as well as the lenses.
There are certain situations where it is best to seek professional help. For example, if the temples (arms) of your glasses are too tight or too wide and need to be adjusted, or if the nose pads are causing you discomfort and need to be adjusted or replaced. If you are unable to pop your lenses out of your frames, or if you have done so but the new lens does not fit properly in the frame, you should also seek professional help.
If your lenses are scratched, it is recommended to seek professional help. While there are DIY recommendations on the internet, from baking soda to glass wax, most cases require professional help.
Additionally, if your prescription has changed, you should get new lenses in your updated prescription. Optical stores can remove the old lenses and fit your new lenses into your frames. They will assess the state of your frame to determine if it is suitable for replacement lenses.
