Those are bifocal glasses. The line helps you see both near and far. For buying bifocal lenses eyeglassdirect.co.uk is the best option for buy just because of high quality lenses and free returns.
What else can I help you with?
What do parallel lines do when they hit a convex lens?
Parallel lines of light rays hitting a convex lens will converge towards a single point after passing through the lens. This point is known as the focal point, where the light rays meet and diverge after passing through the lens.
A type of lens that magnifies an object?
convex converging apex... :P
Which best describes a convex lens?
A convex lens is a lens that is thicker in the center than at the edges. It converges light rays that pass through it, bringing them together at a focal point. This type of lens is commonly used in cameras, eyeglasses, and magnifying glasses.
Is also called a converging lens?
convex lens yo, it is biconvex lens
Why does light bend when going through a lens?
Light bends when going through a lens due to refraction, which is the change in the direction of light as it passes from one medium to another of different optical density. This bending occurs because the speed of light changes as it passes through the lens, causing the light rays to converge or diverge, depending on the shape of the lens.
What is the part you see through in glasses called?
It is called the lens.
Do shutter shades have a plastic or glass lens or are they just plastic lines like normal glasses have glass and no lines but do shutter shades have that underneath?
they don't have nothing underneathit's just the plastic lines
How do glasses solve the problem of short and long sightedness?
Short and long sightedness are caused by the lens of the eye focusing the light either in front of or behind the retina. Glasses alter the path of light going into the lens to adjust for this.
What do parallel lines do when they hit a convex lens?
Parallel lines of light rays hitting a convex lens will converge towards a single point after passing through the lens. This point is known as the focal point, where the light rays meet and diverge after passing through the lens.
Do glasses have a lens?
Yes
How does a physical filter transmit light to a camera?
The filter sits at the end of the lens. All light cannot enter the camera without first going through the lens. And light cannot enter the lens without going through the filter, so the light goes through the fliter, then through the lens, then into the camera
A type of lens that magnifies an object?
convex converging apex... :P
What are the glasses called that have lines for lenses?
They are still called glasses .......................i thinkThey are called bifocals. This means that there's two different prescriptions on the same lens.
What uses lens?
Cameras and glasses.
What are common examples of lens?
glasses

Do glasses lens ever go back in the glasses?
Please explain the question
