Itchy Eyes
It's possible to get itchy eyes with a viral infection, but most commonly itchy eyes are caused by allergy - seasonal or all through the year.
Treatment for allergic conjunctivitis can take on a number of forms:
- If possible, try to identify the allergen, and minimise contact with it.
- Cold compresses can help with symptomatic relief.
- Anti-histamine eye-drops are useful for occasional allergic eye.
- Combination anti-histamine/ mast cell stabilisers work best in situations where an allergic season is well defined.
- More severe cases may require corticosteroid eyedrops to bring the inflammation under control.

What is colour blindness?
The eye determines the colour of what we are looking at by how much response comes from each of three types of light receptors (red, green, or blue). The most common type of colour vision deficiency is where one type of light receptor, usually red or green, doesn't work as well.
This reduces the range and appearance of colours, with some colours that are clearly different to normal eyes appearing the same to a colour deficient people. What do they see? one demo, another.
True colour blindness - black and white only - is very rare. Colour vision deficiencies are usually inherited, and are more common in boys than girls.
