Eyes are windows to our body. About 80% of what we perceive is related to our sense of light, and we can literally reduce the odds of blindness or vision loss through routine eye checkup.
A standard eye checkup is not just about the refraction test, which a test that requires patient to read letters from big to small and eye care practitioner will improve the vision by giving the prescription lenses accordingly. This is what most people know about. However, a standard eye checkup should include screening test from front surface to back surface of our eyes, eye muscles coordination, eye pressure and so on. It is unable to complete without the help of optical instruments respectively.
It is an essential primary ocular health assessment instrument. During the test, eye care practitioner will examine all areas of your eye, including the:
It helps to investigate whether you are free from the ocular diseases such as:
If you are a contact lens wearer, your eye care practitioner can determine the best physical fit to be prescribed through the observation from slit lamp.
While in contact lens aftercare, slit lamp allows the practitioner to make an objective judgment of the interaction between the lens and the eye and a crude assessment of lens spoliation like bio metabolic deposits condition on contact lenses.
It is crucial in handling contact lens wear complication too! This enable practitioner to investigate the corneal diseases induced by contact lenses wear and the subsequent secondary adverse effect.

Our eyes is a bulb-like globe which had its own independent pressure in. You may be heard about Glaucoma, an ocular disease where your intraocular pressure (IOP) is high enough to cause damage on the nerves in the eyes. Glaucoma is currently the second leading cause of blindness globally. This ocular disease can be asymptomatic in early stage until it progresses to damage the nerves lead to narrowing vision and ultimately caused blind.
However, there is nothing to worry about it, as now we can evaluate the pressure in a quick and painless way through the new ICARE® tonometer! What makes it special is ICARE® tonometer requires no anesthetic on patient’s eye! Intraocular pressure evaluation is crucial in early detection of glaucoma. With early detection, glaucoma can be controlled through medications or surgery. Early treatment can protect the eyes against serious vision loss. So it is the time to book an appointment with the optometrist in the available Focus Point outlets now.
Do you ever think where will the light be directed after it enter our eyes? The light is actually refracted and redirected to macula which it located at retina, a layer of photoreceptor cells in the back surface of the eye. This makes us see the beauty in our life. Funduscope is the instrument responsible for vitreo-retinal screening. This portable handheld funduscope can provide a clear image of the health condition of retinal easily without dilating the pupil.
A wide range of risk factors for potential vision loss that involves Vitreous Humour and retinal layer can be diagnosed by Funduscopy. For example if you have diabetes or hypertension, an annual fundus examination is essential for signs of diabetic or hypertensive retinopathy that could lead to a permanent or difficult-to-treat vision loss. Furthermore, age related macular degeneration and papilloedema can be identified by funduscopy.
