Glasses, also known as eyeglasses or spectacles, are devices consisting of glass or hard plastic lenses mounted in a frame that holds them in front of a person's eyes, typically using a bridge over the nose and arms which rest over the ears.

Glasses are typically used for vision correction, such as with reading glasses and glasses used for nearsightedness.

Safety glasses provide eye protection against flying debris for construction workers or lab technicians; these glasses may have protection for the sides of the eyes as well as in the lenses.

Some types of safety glasses are used to protect against visible and near-visible light or radiation.

Glasses are worn for eye protection in some sports, such as squash.

Glasses wearers may use a strap to prevent the glasses from falling off during movement or sports.

Wearers of glasses that are used only part of the time may have the glasses attached to a cord that goes around their neck, to prevent the loss of the glasses.

Diffraction refers to various phenomena that occur when a wave encounters an obstacle or a slit. It is defined as the bending of light around the corners of an obstacle or aperture into the region of geometrical shadow of the obstacle.

In classical physics, the diffraction phenomenon is described as the interference of waves according to the Huygens–Fresnel principle.

These characteristic behaviors are exhibited when a wave encounters an obstacle or a slit that is comparable in size to its wavelength.

Similar effects occur when a light wave travels through a medium with a varying refractive index, or when a sound wave travels through a medium with varying acoustic impedance.

Diffraction occurs with all waves, including sound waves, water waves, and electromagnetic waves such as visible light, X-rays and radio waves.

Sunglasses or sun glasses are a form of protective eyewear designed primarily to prevent bright sunlight and high-energy visible light from damaging or discomforting the eyes.

They can sometimes also function as a visual aid, as variously termed spectacles or glasses exist, featuring lenses that are colored, polarized or darkened.

In the early 20th century, they were also known as sun cheaters (cheaters being an American slang term for glasses).

Fireworks are a class of low explosive pyrotechnic devices used for aesthetic and entertainment purposes.

The most common use of a firework is as part of a fireworks display (also called a fireworks show or pyrotechnics), a display of the effects produced by firework devices.

Fireworks competitions are also regularly held at a number of places.

A woman is a female human.

The term woman is usually reserved for an adult, with the term girl being the usual term for a female child or adolescent.

The term woman is also sometimes used to identify a female human, regardless of age, as in phrases such as "women's rights".

Women with typical genetic development are usually capable of giving birth from puberty until menopause.
