Scientists created telescopic contact lenses

The video tutorial explains how a special lens can be worn comfortably, allowing normal vision through its center. The lens edge acts as a telescope, magnifying light with aluminum mirrors. To switch between normal and magnified vision, special glasses are used. These glasses employ liquid crystals to change light polarization, selectively blocking parts of the lens.

What is the primary function of the center of the lens?

• To allow light to pass through for normal vision

• To magnify light

• To block light

• To change the color of light

How does the edge of the lens enhance vision?

• By changing the color of the surroundings

• By acting as a telescope and magnifying light

• By blocking unwanted light

• By reducing glare

What material is used in the lens to magnify light?

• Glass

• Plastic

• Patterned aluminum mirrors

• Copper

What is required to switch between normal and magnified vision?

• A remote control

• A smartphone app

• Special glasses with liquid crystals

• A manual switch on the lens

How do liquid crystals in the glasses affect light?

• They reflect light

• They increase the brightness of light

• They electrically change the polarization of light

• They change the color of light
