Sunglasses in the context of "Oakley, Inc."

James Ayscough /ˈæsˌkjuː/ (born 1720, died 1759) was an English optician and designer and maker of scientific instruments. He was apprenticed to an optician named James Mann from 1743 to 1747. James Ayscough became known for his microscopes. His shop was in London between 1740 and 1759. Around the year 1752, James Ayscough introduced spectacles with double-hinged side pieces. Although he made clear lenses, he recommended lenses tinted blue or green to treat some vision problems. These spectacles with tinted lenses are believed to be the precursors to sunglasses.

In February 1755 he began to contribute to the Gentleman's Magazine a daily register of the weather, month by month. It included barometric reading of pressure, and two temperature readings, in the early afternoon, and late in the evening. There was also a brief comment on the day's weather. He may have begun the record with instruments that the magazine already owned, (as it had been recording pressure and temperature sporadically since 1747, initially printed at the end of the monthly stock market report.) Initially barometric pressures were read to one-tenth of an inch, but that soon changed to 1/100, suggesting that he made his own instrument. His published register attracted the attention of George Smith near Carlisle, who began to contribute a matching record for Cumberland. This continued until Ayscough's death in 1759; his last entry in his record at London (Clerkenwell) was 23 August 1759.

Eyewear is a term used to refer to all devices worn over both of a person's eyes, or occasionally a single eye (therefore known as a monocle), for one or more of a variety of purposes. Though historically used for vision improvement and correction, eyewear has also evolved into eye protection, for fashion and aesthetic purposes, and starting in the late 20th century, computers and virtual reality.

The primary intention of wearing eyewear can vary based on the need or desire of the wearer. Eyewear comes in different forms, such as glasses, contact lenses, sunglasses and many more. Eyewear (such as glasses and contact lenses) helps most people see clearer or read. Eyewear also can be used for protection, such as sunglasses which protect wearers from the Sun's ultraviolet rays which are damaging to the eyes when unprotected, eyepatches to protect injured eyes from further damage, or goggles which protect the wearer's eyes from debris, water and other chemicals. Variants of eyewear can conversely inhibit or disable vision for its bearers, such as blindfolds and view-limiting device for humans, blinkers for horses, or blinders for birds, especially poultry. Eyewear also exists for other specialized or niche purposes, such as active shutter 3D systems and anaglyph 3D glasses for stereoscopy, and night-vision goggles for low-light environments.

Sunscreen, also known as sunblock, sun lotion or sun cream, is a photoprotective topical product for the skin that helps protect against sunburn and prevent skin cancer. Sunscreens come as lotions, sprays, gels, foams (such as an expanded foam lotion or whipped lotion), sticks, powders and other topical products. Sunscreens are common supplements to clothing, particularly sunglasses, sunhats and special sun protective clothing, and other forms of photoprotection (such as umbrellas). Sunscreen is on the World Health Organization's List of Essential Medicines.

Sunscreen products may be classified according to the type of active ingredient(s) present in the formulation (inorganic compounds or organic molecules) as:
