Primary Eye Care
A primary eye care examination comprises a comprehensive array of investigations to determine the status of your vision and eye health.
The examination includes the following assessments:
- Case history
- Assessment of vision
- Measurement of refractive error
- Assessment of the coordination between the two eyes
- Evaluation of the ability to change focus
- Evaluation of ocular health

Vision and Refractive Examination
2. Visual acuity test
Refraction is through some procedures and with the help of instruments to evaluate the refractive state of our eyes. See if there are refractive errors (such as myopia, hyperopia, and astigmatism).
If necessary, optometrist will perform cycloplegic refraction. This method is to relax the ciliary muscles in the eyes with the help of drugs, especially for the following people:
- People with strabismus
- People with hidden hyperopia
- People with pseudomyopia
Visual function assessment
4. Color vision test
Color vision test is an assessment to diagnose our color discrimination ability.
5. Stereoscopic test
The stereoscopic test can see whether the binocular function of the visual system is normal.
6. Squint assessment
7. Motility test
8. Binocular vision assessment
The accommodation and binocular coordination test mainly check whether the eyes are operating binocularly in harmony while looking at the object.
Ocular health assessment
9. Visual field test
When the eye is focusing on a certain point, the range of the surrounding environment that can be observed at the same time is called the visual field. Visual field examination is particularly useful for testing the health of the optic nerve and retinal cells.
10. Intra-ocular Pressure (IOP) assessment
IOP is an indicator of pressure inside the eye. Most people have intraocular pressure between 10mmHg and 21mmHg. Too high intraocular pressure will damage the optic nerve tissue and adversely affect vision and visual field.
11. Pupillary reflex test
12. Anterior eye examination
Health examination of anterior eye Slit lamp can be used to observe the health of cornea, anterior chamber, crystalline lens and vitreous body.
13. Fundus examination
Through the binocular ophthalmoscope and fundus camera, we can check the retina, including the blood vessels on the fundus. Any change caused by diseases such as diabetes, high blood pressure, and high blood cholesterol level can be detected early.
14. Diagnosis and Management
Eyedrops for dilating pupils may be used during the examination. After dilation, your eyes will become sensitive to light and your near vision may be blurred for approximately 4-6 hours. Please bring a pair of sunglasses or an umbrella to use to minimize discomfort. Do not operate machinery, drive a car, ride a motorcycle or bicycle. Under normal circumstances, the pupils will return to normal after 4-6 hours.
