A vision tester is a medical instrument used in determining the particular defects that eye patients suffer from. It comprises of high power lens that easily detect the defect that the patient is suffering from the moment adjustments are made. It contains a trigger attached to a camera that performs the major task.
The eye tester can be used to verify many eye defects. It can be used to determine defects in those patients that can only see near, those that can only see far and those for which refraction in both eyes differs, to test for corneal reflexes and determine non-uniformity in pupils of the eyes of patients. After the tests prescription suiting the defect is administered to the patient, by a qualified personnel.
Performing an eye screen using this tool is a relatively simple exercise which can be done by practically anyone including non-medical staff. It comprises of a camera controlled by a trigger which captures both eyes on a screen the moment the trigger is pulled, then measurement and determination of the defect is done automatically.
A vision checker on detecting the faults of the patients eyes, results are saved automatically. This is advantageous since a patient can keep checking the progress of his or her eyes by comparing the figures during the various measurements. The results can then be printed out for future reference, or just saved in a computer. The automated nature in operation of this instrument makes it very efficient in the eye testing exercise.
The use of this medical instrument comes with very many advantages. For one, the turn- around time for the test is less than a second. Meaning it can be done on anyone ranging from kids to adults without the attendant or the patient feeling strained in any way. The results derived from the checker are also 100% accurate, leaving both the doctor and the patient satisfied.
The eye tester has got its outstanding characteristics. Screening is done a meter away from the screen, the whole process takes an approximation of 0.8 seconds, testing of both eyes is done at once, detailed recording details are contained in the checker and its accuracy is one hundred in percentage.
This important medical equipment though has got its negative bits. Its affordability is not as such guaranteed especially for upcoming firms. Installing enough of it may need a large capital base. The entire treatment process on the part of patients may also not be as such affordable for everyone.
The vision tester is in the recent days rated among the topmost innovations considering its importance and simplicity in operation. Its use is by day being embraced by more and more people in the world. Through its use, several patients across the world have had their eye defects determined and treatment administered to them accordingly.
