Swollen eyes and eye infections

Irritative conjunctivitis
Irritation can occur from a foreign body (eg grit, eye lash), exposure to very bright light (eg 'arc' eye in welders) or exposure to chemicals such as chlorine in swimming pools, smoke, fumes, onion juice and overly-concentrated contact lens solutions. All can lead to eye redness, soreness and swelling. Treatment may involve saline irrigation of the eye and removal of any foreign bodies ? this can be difficult where, for example, a piece of metal has flown into the eye with force. Pain can be damped down with analgesic drops, and anti-inflammatory drops. An eye patch may be needed to protect the eye during healing.

Action
All but the most mild cases of conjunctivitis need to be assessed by a doctor, as your eyes are too precious to take for granted. Seek medical advice straight away.

• If eyes are sticky, you may be advised to gently wash away discharge with a warm saline solution. Use a separate compress or eyebath for each eye.
• Stop using contact lenses until the problem has resolved.
• If eyes feel dry, you may be able to use lubricating drops known as artificial tears.
• If symptoms are worse on going out, wear sunglasses

Prevention

• Wash hands thoroughly before touching eyes
• Avoid swimming in murky water
• If conjunctivitis is due to an allergy, stop using make-up, creams, nail polish until symptoms resolve, then gradually re-introduce them one at a time to identify triggers
• Use hypoallergenic toiletries where possible - the gentlest shampoos, soaps and moisturiser are those formulated for new born babies.
