A company called, Pixel Optics has developed glasses which change focus when you look near or far. The device consists mainly of an accelerometer & lenses which are covered with transparent liquid crystals. When you tilt your head for near work, the accelerometer detects it and the liquid crystals change the focus of the lenses for near vision. When you look far, again the change is detected by the accelerometer & lenses are adopted for looking far in a fraction of second.

These glasses are a blessing for the persons who are annoyed of the line  in the field of vision, separating the lenses in bifocal glasses.

A recent study published in American Journal of Internal Medicine says that working for more than 11 hours a day increases the risk of heart disease by 67 percent, compared with working a standard 7 to 8 hours a day.

The researchers stressed that a question about the duration of work should be a regular part of history taking by the doctor.They recommended that people who work long hours, should be particularly careful in following healthy diets, exercising sufficiently and keeping their blood pressure, cholesterol levels, and blood (sugar) within healthy limits.
