When a finger or stylus presses down on the top surface, the two metallic layers become connected (they touch), the surface acts as a pair of voltage dividers with connected outputs. This causes a change in the electrical current. The pressure from your finger causes conductive and resistive layers of circuitry to touch each other, changing the circuits' resistance, which registers as a touch screen event that is sent to the computer controller for processing.

The nineties introduced smartphones and handhelds with touch screen technology. In 1993, Apple released the Newton PDA, equipped with handwriting recognition; and IBM released the first smartphone called Simon, which featured a calendar, notepad, and fax function, and a touch screen interface that allowed users to dial phone numbers. In 1996, Palm entered the PDA market and advanced touch screen technology with its Pilot series.

According to Malik Sharrieff, an eHow Contributor, "the resistive system is comprised of five components, including the CRT (cathode ray tube) or screen base, the glass panel, the resistive coating, a separator dot, a conductive cover sheet and a durable top coating."

In 1971, a "touch sensor" was developed by Doctor Sam Hurst (founder of Elographics) while he was an instructor at the University of Kentucky. This sensor called the "Elograph" was patented by The University of Kentucky Research Foundation. The "Elograph" was not transparent like modern touch screens, however, it was a significant milestone in touch screen technology. The Elograph was selected by Industrial Research as one of the 100 Most Significant New Technical Products of the Year 1973.

202374 — Touchscreens come in several types, including resistive, capacitive, infrared, and so on. Each type uses a different mechanism for detecting touch.

SCREEN TIME AT NIGHT: However, at all costs, avoid looking at your screens during your sleep time. Scientists have reason to believe that doing so can disrupt one's sleep as it affects the sleep hormone, melatonin. It isn't just that; this disruption can cause distraction and memory impairment the following day. However, if you have to use screens at night, make sure you do so with your room's lights on.

According to PC Magazine, a touch screen is, "a display screen that is sensitive to the touch of a finger or stylus. Widely used on ATM machines, retail point-of-sale terminals, car navigation systems, medical monitors and industrial control panels, the touch screen became wildly popular on handhelds after Apple introduced the iPhone in 2007."

In 1977, Siemens Corporation financed an effort by Elographics to produce the first curved glass touch sensor interface, which became the first device to have the name "touch screen" attached to it. On February 24, 1994, the company officially changed its name from Elographics to Elo TouchSystems.

REMEMBER THE 20-20-20 RULE: Screen-ing is unavoidable today and having accepted this, there are ways you can still keep your eye health in check. One very effective rule is to work for 20 minutes on screen and then take a 20-second pause, during which you look 20-feet away, preferably at a wall.

IDEAL SCREEN BRIGHTNESS: Experts believe that the ideal screen brightness of your gadget depends on your ambient light. As a simple rule, remember that the brightness of your gadget should be equivalent to the light surrounding you, such that both the lights' radiance is similar. By doing so, they will blend in, causing the least damage to your eyes.

In 1983, the computer manufacturing company, Hewlett-Packard introduced the HP-150, a home computer with touch screen technology. The HP-150 had a built-in a grid of infrared beams across the front of the monitor which detected finger movements. However, the infrared sensors would collect dust and require frequent cleanings.

For a generation that spends eight hours on laptops and rest on mobile, it is a question worth asking - how are our eyes responding to this overburdening? Well, the repercussions are out there with most people facing eyesight issues at a young age. However, to minimize the damage, many think that keeping screen brightness at the lowest is the solution. Is this true? If not, what is the ideal screen brightness level that affects your eyes the minimum?

In 2002, Microsoft introduced the Windows XP Tablet edition and started its entry into touch technology. However, you could say that the increase in the popularity of touch screen smart phones defined the 2000s. In 2007, Apple introduced the king of smartphones, the iPhone, with nothing but touch screen technology.

UNDERSTAND BRIGHTNESS AND CONTRAST SETTINGS: Check your phone and laptop brightness settings and don't forget to alter the contrast also. Contrasting it right can make a world of difference. For example, if you prefer a low screen brightness but are afraid of straining your eyes, you can increase the contrast of your gadget and it can solve the problem for you.

Capacitive touch screens use a layer of capacitive material to hold an electrical charge; touching the screen changes the amount of charge at a specific point of contact.

HARMS OF TOO DIM BRIGHTNESS: If the brightness of your gadget is too low, you will end up straining your eyes. This happens because you may have to focus a little strainfully. Although, this will not cause any long term damage but can lead to headaches.

SHOULD YOU KEEP IT BRIGHT? Again, this is not ideal either. If you keep the screen brightness of your gadget at higher than 50 per cent, you still may not risk a permanent damage but many short term problems, such as digital eye strain, eye irritation and dry and fuzzy eyes.
