Occuvision and Covid-19
Everyone is concerned about minimising their exposure to, and the spread of, SARS-CoV2. And rightly so. You limit your contact with others and sanitise everything you touch. But work and life must continue as much as possible at the same time. We get it. Please watch this short Health & Safety message from our Managing […]
Glaucoma
Introduction Glaucoma is a nerve disorder of the eye, damaging the optic nerve and causing a loss of vision. Increased pressure in the eyeball is often associated with glaucoma. Both the anterior and posterior chambers of the eye are filled with a thin fluid called the aqueous humor. The fluid is produced in the posterior […]
Safety spectacles
Safety spectacles are intended to shield the wearer’s eyes from impact hazards such as flying fragments, objects, large chips, and particles. Workers are required to use eye safety spectacles with side shields when there is a hazard from flying objects. Non-side shield spectacles are not acceptable eye protection for impact hazards. The frames of safety […]
Eye injuries
The structure of the face and eyes is well suited for protecting the eyes from injury. The eyeball is set into a socket surrounded by a strong, bony ridge. The eyelids can close quickly to form a barrier to foreign objects, and the eye can tolerate a light impact without damage. Even so, injury can […]
Diabetes Mellitus
Introduction Diabetes Mellitus is a disease that occurs when the pancreas does not secrete enough insulin or the body is unable to process it properly. Insulin is the hormone that regulates the level of sugar (glucose) in the blood. Diabetes can affect children and adults. How does diabetes affect the retina? Patients with diabetes are […]
Common eye problems (sight threatening)
Cataracts A cataract is a clouding of part of the eye called the lens. Vision becomes blurred or dim because light cannot pass through the clouded lens to the back of the eye.Cataracts can form at any age, but most often in older people. In younger people they can result from injury, certain drugs, long-standing […]
Common eye problems (non-sight threatening)
These are mostly conditions that cause unclear vision (blur), but will not harm the eye if not attended to immediately. Shortsightedness (myopia) Occurs when light is focused in front of the retina and causes distance vision to become blurred. Near vision, however, is usually clear. Long-sightedness (hyperopia) Occurs when the natural tendency is to focus […]
Colour vision
Overview Colour vision deficiency may be a hereditary condition or caused by disease of the optic nerve or retina. Acquired (not from birth) colour vision problems only affect the eye with the disease and may become progressively worse over time. Patients with a colour vision defect caused by disease usually have trouble discriminating blues and […]
Cataracts
Cataracts are often encountered and misunderstood in everyday life. A cataract is a cloudiness (opacity) in the eye’s lens that impairs vision. It is often confused with a pterygium (pronounced tih-ree-jum) – a fleshy growth of the conjunctiva onto the cornea. Cataracts produce a progressive, painless loss of vision. Their cause is often not […]
