Sometimes, simply changing a work environment to have better ergonomics is all that needs to be done to reduce eye strain and other vision problems related to CVS. In some cases, a good pair of computer eyeglasses may help someone see better at the right distance range needed for looking at a computer screen.
A way of preventing CVS is to take breaks while using computers.

Dale Jarrett
Dale Arnold Jarrett (born November 26, 1956) is a retired American racecar driver. Jarret used to drive in the Monster Energy NASCAR Cup Series. He won the 1999 Winston Cup championship and the 1993 Daytona 500. Jarrett has been called one of NASCAR's 50 greatest drivers. Jarrett retired in 2008 and now does Commentary for NBC. His father is NASCAR legend Ned Jarrett.
2007 Formula One espionage controversy
The 2007 Formula One espionage controversy, also known as "Spygate," or "Stepneygate" involves claim that the teams passed confidential technical information. It was claimed that McLaren Formula One had information from the Ferrari team. Then it was claimed that Renault F1 had information from the McLaren team.
The case involved Nigel Stepney, who used to work for Ferrari and was working at the time for McLaren. It also included Mike Coughlan, who was working for McLaren and his wife Trudy Coughlan. Ferrari claimed that Stepney stole confidential technical information. This became the subject of legal action in Italy and an FIA investigation. The case in England was dropped after Ferrari reached an agreement with the Coughlans.
The FIA penalized McLaren. The biggest penalty was that McLaren excluded (not allowed to compete) from the Constructors' Championship. They were also fined a record-breaking $100 million (USD).
Then the FIA claimed Renault F1 had information about the 2006 and 2007 McLaren cars. Renault were found guilty of breaking the same regulation as McLaren, but Renault was not punished.
Nigel Stepney was working at Ferrari with Jean Todt, Ross Brawn and Rory Byrne. Michael Schumacher was their superstar driver. They were part of the team given the credit for changing the of fortunes of Ferrari in the late 1990s.
In February 2007, Stepney said he was unhappy with some management changes made at Ferrari. On 3 July 2007, "Gazzetta dello Sport" reported that Ferrari had fired Stepney as a result an internal investigation.
The same day Ferrari fired Stepney, they announced taking action against an engineer from McLaren, later named as Mike Coughlan. Coughlan was suspended by McLaren as a result. Court details released say that Mike Coughlan is accused to be in possession of Ferrari documentation, and that his wife is accused of photocopying them.
On 8 November 2007, the FIA announced that the Renault F1 team would be need to answer a charge of possession of confidential information relating to the 2006 and 2007 McLaren Formula One cars. The statement issued by the FIA states that Renault F1 was found to have information used by the 2006 and 2007 McLaren F1 cars.
On 6 July 2007, Honda Racing F1 released a statement confirming that Stepney and Coughlan approached the team regarding "job opportunities" in June 2007. Honda said that no confidential information had been offered or received.
Lithium oxide
Lithium oxide is a chemical compound. Its chemical formula is LiO. It contains lithium and oxide ions.
Lithium oxide is a white solid. It is a strong base. It is corrosive when dissolved in water. Lithium oxide dissolves in water to make lithium hydroxide. It reacts with acids to make lithium salts. It reacts with carbon dioxide to form lithium carbonate. Lithium carbonate is much less corrosive. It makes a red color in a flame.
When lithium is burned to air, it forms lithium oxide. This reaction also makes lithium nitride. It can also be made by heating lithium peroxide.
It is used as a flux in glazing ceramics. It can be used in scientific research. It could also be used in lithium ion batteries.
Lithium oxide is very corrosive. It reacts with water to make lithium hydroxide. It is toxic because of its strong alkalinity (being a base).
Lithium carbonate
Lithium carbonate is a chemical compound. Its chemical formula is LiCO. It contains lithium and carbonate ions.
Lithium carbonate is a white solid. It dissolves in water, although not as much as sodium carbonate. It reacts with acids to make carbon dioxide. It can react with carbon dioxide temporarily to make the bicarbonate. lithium carbonate is basic in nature.
It can be made by mixing lithium oxide or lithium hydroxide and carbon dioxide.
Lithium is extracted from two main sources: pegmatite crystals and lithium compounds from brine pools. It is also found in the rare mineral zabuyelite.
Lithium carbonate is used in various medications for treating bipolar disorder. It is also used in fireworks to make a bright red color. It is used in processing metal oxides. It can be used to make glass. It is used to glaze ceramics. It can also be used to dry cement. It is used in making lithium ion batteries. It is used in carbon dioxide detectors. It is also used make the cathodes of most lithium-ion batteries, which are made from lithium cobalt oxide.
Lithium carbonate is somewhat toxic. It is a base, and reacts with strong acids.
Lithium chloride
Lithium chloride is a chemical compound. Its chemical formula is LiCl. It contains lithium and chloride ions.
Lithium chloride is a colorless solid. It makes a bright red color in a flame. It absorbs water, unlike other alkali metal chlorides. It also dissolves more easily in water than other alkali metal chlorides.
Lithium chloride can be made by igniting lithium and chlorine, but it is difficult because the reaction is violent. This makes the anhydrous (without water attached) form. Another way is mixing lithium oxide, lithium hydroxide, or lithium carbonate with hydrochloric acid. This makes the hydrate (water attached to the molecule). The hydrous form can be dried to the anhydrous form by heating it with hydrogen chloride gas.
Lithium chloride is used to make lithium metal. Lithium chloride is melted and electrolyzed. This makes liquid lithium metal. It is used to dry air. It is also used as a flux for aluminium. It can be used in making organic compounds. It can be used to color flames red.
Lithium chloride is somewhat toxic. It was going to be used as a salt substitute but people found that it is toxic. It affects the central nervous system.
Oxidation state
The oxidation state (or oxidation number) of an element is used to predict what sort of chemical compounds form.
For example, if you put hydrogen and oxygen together, they form HO, and not HO because the oxidation number of oxygen is −2, which means that we need two +1 hydrogens for the numbers to balance.
You can look up the oxidation state(s) of an element on many periodic tables. They are usually between −2 and +3.
Oxidation states were invented by Antoine Lavoisier to predict how oxygen reacted in chemical reactions; hence the name. Later on, we learned that Lavoisier's theory can be used to predict other reactions too, many of them have nothing to do with oxygen.
In ionic compounds, oxidation states tell us about the movement of charge within the compound. For example, chlorine has a very high electronegativity which means that it really likes electrons and sodium has a very low electronegativity which means that it really hates electrons. When sodium and chlorine are close together, sodium will give away an electron to chlorine. A change in charge has taken place; chlorine's charge has gone down which we call reduction, and sodium's charge has gone up which we call oxidation.
