To see correctly, yes you do.
we need convex lens in eyes as convex lens bulges out and thus focuses the outside light rays at a particular point in our eye, so then only we are able to see.
A 1300mm lens can see to infinity.
To see near objects clearly, you need greater curvature of the eye's lens. This increased curvature allows the lens to bend light rays more sharply, focusing them directly on the retina for close vision. In contrast, for distant objects, the lens flattens and has less curvature.

a lens you can see through and a mirror reflects
no it is clear.
No, the lens in your eye is necessary for focusing light onto the retina, allowing you to see clearly. Without a lens, your vision would be blurry.
heyy x a lens help you see in the light
Cornea/lens.
they both can see very far or very close and both can see things
The lens of the eye needs to change shape in order to focus light onto the retina at the back of the eye, allowing us to see objects clearly at different distances.
If you see a black dot on your camera lens, you should try gently cleaning the lens with a soft cloth or lens cleaning solution. If the dot persists, it may be a scratch or damage to the lens that requires professional repair or replacement.
