Your Eyes

Sunglasses today are commonly used as a fashion accessory.

Sunglasses are an effective and affordable way to protect eyes from UV damage.

UV damage occurs in the morning from 8.00 - 10.00 and in the afternoon from 2.00 - 4.00.

Not all sunglasses provide UV radiation. Such sunglasses are harmful to eyes because the darkened filter causes pupil dilation that allow more light to enter the eyes.

Sunglasses were in fashion in the 1930s. Nowadays people cannot imagine a day without sunglasses.

Do UV coating on your sunglasses have an expiration date?

The good news is - no they don't.

Moving ? You'll Need It

Made from polyethylene (LDPE) film with air bubbles, the bubble pack cushions fragile items during transit.

Invented by Alfred Fielding and Marc Chavannes in 1957.

Alfred Fielding was born 31 August 1917 in Kirkland. Died 7 July 1994 in Kirkland, Washington at age 76.

Marc Chavannes was born on 2 March 1896 and died on 6 April 1994 in Sarasota County, Florida at the age of 98. Chavannes is a native of Switzerland and spent part of his professional life as a judge on the World Court and at the League of Nations before entering business.

Air is not injected into all those tiny bubbles. Instead, it is trapped between two sheets after they pass over several rollers, one of which creates the indentations for the bubbles.
