### Why Should You Get an Eye Test?
We all know we should get eye tests – so why don’t we?
Did you know that nearly half of all sight loss can be prevented? Regular eye exams are one of the best ways to keep your vision in great shape. The NHS recommends having an eye test at least once every two years. These checks not only help prevent diseases but also improve comfort.
Feeling a bit nervous about the process? Don’t worry. Here’s a breakdown of what happens during an eye test to help you feel more at ease and prepared for your visit to the optician:
### Pre-test Preparations
Before your actual eye test begins, an assistant will gather some basic details and create a record of your vision. Here’s what typically happens:
1. **Pressure Test:** They will use a non-contact tonometer to measure the pressure inside your eyes. This involves a few gentle puffs of air and helps detect early signs of glaucoma.
2. **Curvature and Focus Tests:** The curvature of your eyes will be measured, and your field of vision and focusing ability will be tested through simple exercises.
3. **Photos:** Detailed photos of your eyes will be taken for records and to help your optician with the evaluation.
### Optician’s Check-up
After the pre-test procedures, you’ll meet with the optician for a full examination. Here’s what you can expect:
1. **Background Questions:** The optician will ask you some general questions about your vision, lifestyle, and family history related to eye health.
2. **Retinoscope Test:** A retinoscope will shine a light into your eye, using various lenses to determine the type of prescription you might need.
3. **Test Chart:** The familiar eye chart test follows. You’ll read lines from a chart at a distance, with different lenses placed in front of your eyes until the clearest image is found.
4. **Ophthalmoscope Examination:** In a darkened room, your retina, optic nerve, and eye blood vessels will be examined with an ophthalmoscope to check for conditions like high blood pressure or diabetes.
5. **Slit Lamp Examination:** This test checks the health of your cornea, iris, and eye lens.
6. **Visual Field Scanner:** This tool checks for any blind spots in your vision and assesses if you need different glasses for reading and distance.
### Post-test Guidance
Once all the testing is complete, your optician will explain their findings and let you know if you need glasses or an updated prescription. A staff member will then help you choose a suitable set of frames and lenses or provide advice on contact lenses to ensure your vision is the best it can be.
By understanding what to expect, you can approach your eye exam with confidence. Regular eye tests are crucial for maintaining good eye health and catching potential issues early.
