Goggle lenses don't have magnifying power because the front and back of the lens is curved the same. Lenses only have refracting (magnifying or size-reducing) power if the front of the lens is curved differently than the back of the lens. If the curvatures produce a lens that is thicker at the center than at the edges, then it will magnify. A lens that is thinner at the center than at the edges will be size-reducing.

the lens of our eyes is different to the lens of a magnifying glass-it can change its shape from thick to thin
Not at all. The focal length is determined by the curvature of the surfaces.
Excellent question. The answer is actually yes! According to the lens makers formula, it will change based on the refractive index of the material of the concave mirror wrt the medium. Google Lens makers formula for better understanding! NO! the focal length of the mirror will not change if it would be a lens then the focal length would change. The lens maker's formula is for Lenses only!
no need to wear goggles

Removing the lens: 1. With one hand, hold the lens with your thumb and index finger close to the outside edge of the frame near the buckle. 2. With the other hand, hold the frame near the buckle. 3. While holding the lens in place, lift the frame over the lens, "peeling" it toward the center of the goggle. It should "pop" right off. 4. Swap in your new lens into the gasket, ensuring it properly secured in the skirt. Putting the goggle back together: Place the loose frame over the lens nearest the center of the goggle first and using your thumbs, "walk" the frame back over the lens on both sides simultaneously until you get to the buckle side and feel a "pop".
Go on goggle and hold that tollbar down
