Eye examination

Generally an eye exam is recommended every 2 years. For some individuals, such as those with moderate or high prescriptions or those who have underlying medical conditions such as diabetes, it is recommended to have a check more frequently.

Steps in an eye examination .

History - Your optician will take a detailed history of your previous eye health and record any relevant information. They will note any problems or symptoms you are having. Often if you are on any medication for general health complaints it is a good idea to have a list of the various medications you are taking.

External Exmaination  . - The front of the eyes and the eyelids are examined under magnification using an instrument called a slit lamp, basically a type of microscope.

Vision exam - Using a series of lenses and the classic letter chart, combinations of lenses are placed in front of the eyes to obtain the sharpest vision possible. With young children or those who are not familiar with the Alphabet, targets such as pictures or circles can be used.

Often people are concerned they will give the wrong answer and as a result get an incorrect prescription . This is very rarely the case as the optometrist is experienced in judging not only the answer given but also the confidence of the answer and will be able to interpret even the most sketchy of responses .

Retinal Examination - Using a combination of an ophthalmoscope ( a hand held instrument for looking into the eyes ) and a Digital Retinal Camera , the optometrist will examine the structures inside the eye and ensure all is well .

Tonometry - This involves using an instrument to asses the pressure of the fluid inside the eye . It is rapid , completely painless , and allows them to asses the risk of Glaucoma .

Fields Test - Using an instrument called a perimeter , the optometrist checks the peripheral vision , so as to ensure not only do you see in front of you , but also ensure you are aware of things which are visable to the edge of your vision .

At the end of the exam , they will summarise and discuss any findings and make recommendations about spectacles , and contact lenses , depending on your day to day visual needs .
