A tonometer is defined as an instrument used for healthy a check-up of eyes. Its work is to calculate the pressure exerted by the fluid inside a person’s eye. This pressure is measured in the terms of millimeters of mercury, in terms of mmHg. These checkups help in detecting the healthiness of the eye as well as the optic nerves. Tonometers are available in a wide range. Some of these instruments directly touch the eyeball whereas some of them only touch the outer portion of the eyelid.
Necessity of tonometer Types of this equipment also include those that doesn’t touch the eye at all. The reason behind the invention of tonometer is that the pressure inside the eye should vary from 10mmHg to 21mmHg. Having too low pressure can cause the inflamed iris and glaucoma. These problems can often lead to decrease in vision. Such problems are examined by optometrists with the help of a tonometer. In most of the tonometry methods, doctor’s aim at the flatten part of the cornea so that they can easily measure the eye pressure. In electronic indentation tonometry, a rounded tip of a tool that looks like a pen is directly placed over the cornea to note down the pressure.

Vision therapy tools These tools include various types of cards, which are designed to use with accommodative as well as ocular therapies. All these cards come packed inside a well-coated re-usable plastic. You can use these cards with erasable markers. Optical strain can also be reduced with the help of prism sets.
