no need to wear goggles
Smith Optics is an upscale manufacturer of, primarily, sunglasses. The company also makes specialized goggles, such as for skiing or motorsports, and has lens, accessory, and even apparel lines.
The cornea does not hold the lens of the eye in place, it can only hold contact lenses in place. The lens of the eye is in a bag called the lens capsule and the lens capsule is held in place by the lens zonules.
The lens power increases as the curvature of the lens surface becomes steeper. A lens with a larger radius of curvature will have a lower power, while a lens with a smaller radius of curvature will have a higher power. This relationship is described by the lensmaker's equation, which relates the power of a lens to the refractive index of the lens material and the radii of curvature of its surfaces.
A suspensory ligament suspends and holds, or assists in the holding of a joint alignment, an organ, or organ component in place. Examples would be the lens being held in alignment with the aperture and retina of the eye, or the juxtaposition of the patella and joint alignment of the knee.
It's because to change focus, the eye distorts the lens and so the lens has to be flexible. In camera lenses, the lens elements are moved back and forth to focus - it's difficult to see how that kind of mechanism could evolve; but the lens distortion system is similar(ish) to the way muscles work.

To change an electric goggle lens, you typically need to locate the release mechanism on the frame, which can vary depending on the brand and model. Once you have found this release mechanism, you can follow the manufacturer's instructions to detach the existing lens and attach the new one securely. Be sure to handle the lens carefully to avoid scratching or damaging it during the replacement process.
The thick lens equation is used in optics to calculate the focal length of a lens that is not thin, taking into account the thickness of the lens itself.
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.
Both use the principle of optics.
An eyelid for me and thee, or a lenscap for various glass optics.
The lenses have different responsibilities. A optic lens is often concave which means it fold inward. An anatomy lens is mostly convex which means it folds outwards. Both lens' help you see.
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".

One way to prevent goggle lenses from fogging up using chemistry is to apply an anti-fog solution that contains surfactants. Surfactants reduce the surface tension of water droplets on the lens, preventing them from forming fog. This solution can be applied to the lens and then wiped off to create a thin film that helps to keep the lens clear.
