THE EYE TEST EXPLAINED
Step 1- At the optician
The Optical assistant will collect personal data such as:
· Contact telephone number
· GP details
· and other
They will also ensure all your record is up to date.
Step 2- FDT Visual Field Instrument
Screening of your field of vision i.e. central and peripheral vision.
Step 3 – Pressure check
Screening of intraocular pressures is performed with an instrument which directs a puff of air on to the eyes.
Step 4 - About Your Health and Lifestyle
The optician asks questions about your current health, your family’s health, your occupation and your lifestyle. It is very important to get a good understanding of your vision especially if you come in with a specific problem.
Step 7- Retinoscopy
The Optician sometimes uses a retinoscope that casts a beam of light to the back of your eyes and back into the instrument. Different lenses focuses the reflected beam until it is stable, which gives an accurate indication of the strength you need. Retinoscopy is very accurate. It is also used to measure people with communication difficulties, who find it to hard to describe, how clearly they can see.
Step 8- Subjective refraction
The optician will ask several questions where you will need to compare different level of clarity so that the correct prescription for glasses can be found. If you are 40 or above you will need a correction for reading (presbyopia). See prescription explained.
