Eye health

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.

Eye conditions

A list of some common eye conditions can be found below:

Acanthamoeba Keratitis
Poor contact lens hygiene often causes this rare but serious eye infection.

Allergies
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.

Bell’s Palsy
This condition causes sudden paralysis of one side of the face. Because of inability to blink, you may develop severe dry eye.

Blepharitis
Inflammation of the eyelids can cause chronic eye irritation, tearing, foreign body sensation and crusty debris.

Cataracts
If you live long enough, it’s likely you eventually will notice cloudy vision from cataracts.

Chalazion
A swollen bump in the eyelid could be a chalazion.

Colour Blindness
Inability to see all colours.

Corneal Ulcer
Most cases of corneal ulcer are due to a bacterial infection that invades the cornea.

Detached Retina
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
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.

Macular Hole
Suddenly blurry or distorted vision, especially in seniors and diabetics, may mean a macular hole.

Nystagmus
Uncontrollable eye movements from nystagmus often have neurological causes.

Ocular Migraine
Ocular migraine causes a sensation of looking through shattered glass.

Ocular Rosacea
Eyelid irritation.

Optic Neuritis and Optic Neuropathy
An inflamed optic nerve can cause blurry vision and blind spots.

Photophobia
Sensitivity to light.

Pinguecula and Pterygium
Growths on the eye.

Red Eyes
Red eyes can be caused by allergies, eye infections and eye injuries. Learn more causes of red eye and how to treat bloodshot eyes.

Sjogren’s Syndrome
Dry eye is a common symptom of this autoimmune disorder.

Strabismus
Colloquially known as crossed eyes.

Stye
An abscess in the eyelid.

Subconjunctival Hemorrhage
Sudden redness in the white of your eye.

Swollen Eyelids
Sometimes called an eyelid cyst.

Uveitis
