Types of Frames

There are three kinds of frames that can be used with Envision Glasses:

1. Titanium Frame: These are the standard lightweight frames that are shipped with every pair of Envision Glasses. These frames do not have lenses or the possibility to attach them. It has a sleek, minimalist design, and the frame itself is made of titanium, which makes it very durable.
   
2. Protective Smith Optics Frames: These are slightly larger frames and hence can accommodate larger lenses that provide greater coverage of the eye. This frame comes with zero-power lenses and can be purchased as an accessory with the Envision Glasses. The zero-power lenses can be replaced by taking them to your preferred optician with custom tinted lenses or polarised sunglasses in addition to your applicable prescription.
   
3. Fashion Lux Frames: These stylish designer frames come with elegant prints and clear lenses that can be purchased as an accessory with Envision Glasses. The clear lenses can be replaced by taking them to your preferred optician with custom tinted lenses or polarised sunglasses, in addition to your applicable prescription. We currently offer two styles of this frame with the following names:
   
   Fashion Lux Frames Sajama Tortoise
   
   Fashion Lux Frames Avella Granite
   

When you purchase your Envision Glasses, by default they are already attached to the Titanium Frame, therefore should you decide to order an additional Fashionable Lux or Protective Smith Optics Frame, you will have both the Titanium Frame and the additional frame ordered. 

If they detach, here are the instructions on how to reattach them. These instructions can also be used for the Fashionable Lux or Smith Optics Frame, in which case the right earpiece must first be detached to allow the Envision Glasses Body to take its place. 

Before we get started, please note the following:

1. While attaching or detaching the frames, your Envision Glasses may power on. This is because when your Envision Glasses are off and folded, as soon as you unfold them, they will automatically turn on within 45 seconds. This is normal and expected behavior of our hardware, for more information on this topic, see Power Button
2. During this process, we will use the Hinge Button, which is located where the Titanium Frame meets the plastic body of your Envision Glasses. It is located on the top of the glasses body, and pressing may activate Voice Commands
3. In the following instructions, we will use two parts of the Envision Glasses. The frames will always be located on the left side and the Envision Glasses Body will always be located on the right side. The Envision Glasses Body is the main part of the Envision Glasses and it features the processor, the battery, the speakers, and the camera. It is shaped like one half of a spectacle frame and sits on your right ear when you put it on. It weighs roughly 45 grams.

Detach and Attach the Titanium Frame

When you purchase your Envision Glasses, by default they are already attached to the Titanium Frame. This frame does not have lenses or the possibility to attach lenses.

Step 1: Take your Envision Glasses off your face and make sure they stay in a folded-out position. This means that the front of the Envision Glasses Body, where the camera and display are located, is folded out.

Step 2: With the left hand hold the temple of the Titanium Frame keeping the left thumb above the frame and the other four fingers below.

Step 3: Do the same with the right hand but hold the Envision Glasses Body with the right thumb above and the other four fingers below. Hold your hands slightly forward to bring your right thumb on top of the circular part of the Envision Glasses Body. This circular part is on top of the Hinge Button that is used to activate the Voice Commands and, at the same time, the Hinge Button that connects the frame to the Envision Glasses Body.

Step 4: Now that your hands are in the correct position to detach the frame, make sure that with your right thumb, you are pressing the circular part and ensure also that your index finger is still under the Envision Glasses Body in front of your thumb. This is very important as your index finger will resist the front from folding inward, which will prevent you from detaching the frame.

Step 5: While pressing the Hinge Button with your right thumb and making sure that the front of the Envision Glasses Body is resisted with your right index finger, we will rotate the frame counterclockwise, or if the Envision Glasses are in front of you pointing forward, turning them towards you, you will need to rotate them about 25 to 40 degrees or about 6 to 10 centimetres, that is, about 2 to 4 inches towards you. When you do this correctly, you will feel some resistance on the Hinge Button on the right side, which means that the frame has separated from the Envision Glasses Body. If you feel no resistance, it means that the front of the Envision Glasses Body is rotating and you are not putting up enough resistance with your right index finger to prevent it from rotating. 

Step 6: You can now release your right hand and leave the Envision Glasses Body on the table. If the frame has not yet detached from the body, you may need to wiggle it up a little.

Step 7: Now let's reattach the Titanium Frame with no lenses. Be sure to start in the same way you detached the frame, with the Titanium Frame facing you on the left side table, unfolded, and the Envision Glasses Body facing you on the right side table. With the camera facing forward and the Hinge Button facing the ceiling.

Step 8: Grab the Envision Glasses Body with the right hand in the same way, such that the right thumb is on the Hinge Button, where the circular part should come at the top. With the left hand, grab the Titanium Frame, but this time with the left thumb on the circular part. When you do this, the Titanium Frame should be at the same angle you took it out, that is, about 30 to 45 degrees, the circular part will fit right on top of the Hinge Button and you may need to move it a little or find a way to make the circular part fit on top of the Hinge Button. 

Step 9: Whenever the Titanum Frame is locked at the top, switch the left thumb with the right thumb to get your right thumb back on the circular part. 

Step 10: Now with your left hand you have to rotate the Titanium Frame again, but this time clockwise about 30 to 45 degrees or about 6 to 10 centimetres, that is, about 2 to 4 inches towards you.

Step 11: Once you have done this, you will hear a click, at which point you can release your right thumb and the Titanium Frame will be attached to the Envision Glasses Body.

Detach and Attach the Protective Smith Optics Frame

Should you prefer to have frames with lenses, you can order additional Fashion Lux or Protective Smith Optics frames, which will be shipped in a separate box. You can interchange them easily by detaching the default Titanium Frame and attaching the additional frame ordered.

The following instructions will provide you with detailed steps on how to detach the Titanium Frame and attach the frames with lenses: 

Step 1: To detach the Titanium Frame again, please rotate the frame counterclockwise while keeping your right thumb on the Hinge Button on the Envision Glasses Body. We are now left with the Envision Glasses Body without the frame.

Step 2: Now, we're going to take the Smith Optics Frame, which comes in its own protective case. We're going to unzip it and take the Smith Optics Frame. First of all, we're going to make sure that we unfold the Smith Optics Frame, both the temples and the protective sides on the inside that provide extra protection.

Step 3: Let's place it in front of us on the table with the temples facing you. Now, just as we did when we detached the Titanium Frame, hold the right temple with your right hand and the left temple with your left hand. The right thumb should be above the circular button and at the same time holding the right index finger below the button.

Step 4: With your right thumb, press the button and, while pressing it, rotate the right temple clockwise or move your wrist to the left between 30 and 45 degrees. This will ensure that the right temple separates from the rest of the Smith Optics Frame. If not, be sure to press the circular button firmly and try turning it a little further, as this will help to separate the right temple from the Smith Optics Frame. At this point, we have the Smith Optics Frame without the right-hand mock temple that will have to be attached to the Envision Glasses Body that we have just separated from the Titanium Frame. 

Step 5: Let's grab the Envision Glasses Body again with the right hand and with the right thumb on top of the Hinge Button. With my left hand, grab the Smith Optics Frame and hold the left thumb on top of the circle part. Do this by wrapping your left hand around the front of the Smith Optics Frame and holding your left thumb on the top of the circular part. Your left index finger should be now in front of the lenses and your left thumb should be on the top of the circular button. 

Step 6: Now move the left thumb with the Smith Optics Frame to the right thumb on top of it. Once you are here, move the right thumb down to be able to place the circular part on top of the Hinge Button of the Envision Glasses Body. As you do this, the Smith Optics Frame should be at the same angle at which you took it out, which is 30 to 45 degrees to the left. The circular part will fit just on top of the Hinge Button, but sometimes it may be necessary to wiggle it a little when it is locked at the top.

Step 7: Replace the left thumb with the right thumb, making sure that the right thumb is now back on the circular part, which is now on top of the Hinge Button. This means that the Smith Optics Frame is attached to the Envision Glasses Body. 

Step 8: Now with your left hand you will have to rotate the Smith Optics Frame again but this time clockwise about 30 to 45 degrees or about 6 to 10 centimetres, that is, about 2 to 4 inches towards you.

Step 9: Once you have done this, you will hear a click, at which point you can release your right thumb and the Smith Optics Frame will be attached to the Envision Glasses Body.

Step 10: If you wish to interchange the Smith Optics Frame for the Titanium Frame at any time. It works in the same way as detaching the Titanium Frame. Please refer to the instructions above to do so. 

Note: If you ordered one of the Fashion Lux frames, you can follow the same steps, as the attachment and detachment mechanism functions in the same way. 

Detach and Attach the Smith Optics Protective Sides

You can also remove the protective sides if you don't need them or don't like them. These are attached to the Smith Optics Frame at the top and bottom with a tight fitting system on which they rotate. Note that this is a little more complicated and you may need help from someone to remove these. You can check at your own pace with a chosen family member or friend this video tutorial that will set you up to successfully remove the protective sides or take them to your preferred optician.

Step 1: First, turn the right protective side inward and rest your right index finger on the inside and, with your right middle finger and right thumb, squeeze the sides of the side. Squeeze hard enough and pull a little, the fit at the top or bottom will loosen and you will be able to remove it. Do exactly the same with the left protective side.

Step 2: To reattach them, you will notice two small dots on each protective side on both sides. These should come respectively on the top and bottom of the Smith Optics Frame.

Step 3: To reattach, use your right hand to hold the right protection side and your left hand to hold the Smith Optics Frame. Make sure to use your thumb to locate the bottom point and the small hole in the Smith Optics Frame and insert it. Press from bottom to top to make it fit.
