Blepharitis is an inflammatory condition of the eyelids. Material secreted by the eyelids builds up on the lid margin and they become red and sore. Regularly cleaning the eyelids will help. Add baby shampoo to water which has been boiled and left to cool until warm. Clean your hands, then apply cotton wool pads dipped in the solution to the eyelids. Leave for several minutes to loosen the material, repeating with a fresh the pad. Then take a cotton bud and dip it into the solution. Gently rub the cotton bud across the upper and lower eyelid margins, removing the debris. Repeat the process, ensuring you use a fresh cotton bud each time. Carryout this process regularly and the condition should improve.
