Having an eye examination at least once every two years should be part of everyone’s health care routine.
The complexities of exactly how our eyes work is intriguing and looking after our eyes is important. Over half of all sight loss in the UK is preventable. Visit your optometrist to catch sight loss early.
Seeing can be likened to the process of taking pictures on a film with a camera which you then get developed. The retina is like a camera film which stores an image of what we are looking at. The image directed onto the retina is then sent along to the brain where it is processed, like developing a camera film. Therefore we actually “see” in our brain with the light information sent to it from our eyes. This whole process happens very quickly so that everything we see is in focus.
A list of some common eye conditions can be found below:
Poor contact lens hygiene often causes this rare but serious eye infection.
Itchy, red, swollen, tearing eyes may mean eye allergies.
Amblyopia (Lazy Eye)
Amblyopia (or “lazy eye”) is a vision development problem in infants and young children that can lead to permanent vision loss.
This condition causes sudden paralysis of one side of the face. Because of inability to blink, you may develop severe dry eye.
Inflammation of the eyelids can cause chronic eye irritation, tearing, foreign body sensation and crusty debris.
If you live long enough, it’s likely you eventually will notice cloudy vision from cataracts.
A swollen bump in the eyelid could be a chalazion.
Inability to see all colours.
Most cases of corneal ulcer are due to a bacterial infection that invades the cornea.
Flashes of light and floating spots are classic warning signs of a detached retina.
Dry Eye Syndrome
Dryness and redness of the eye.
Eye Occlusions (Eye Strokes)
Sudden vision loss can occur when a clot or blockage interrupts blood flow to vital eye structures.
Eye twitching, eyelid tics and spasms.
Floaters, Flashes and Spots
Eye floaters and flashes may be harmless, or they may signal a serious problem, like a detached retina.
Suddenly blurry or distorted vision, especially in seniors and diabetics, may mean a macular hole.
Uncontrollable eye movements from nystagmus often have neurological causes.
Ocular migraine causes a sensation of looking through shattered glass.
Optic Neuritis and Optic Neuropathy
An inflamed optic nerve can cause blurry vision and blind spots.
Sensitivity to light.
Pinguecula and Pterygium
Growths on the eye.
Red eyes can be caused by allergies, eye infections and eye injuries. Learn more causes of red eye and how to treat bloodshot eyes.
Dry eye is a common symptom of this autoimmune disorder.
Colloquially known as crossed eyes.
An abscess in the eyelid.
Sudden redness in the white of your eye.
Sometimes called an eyelid cyst.
Painful inflammation of the uvea causes light sensitivity, floaters and blurred vision.
