People who wear reusable contact lenses should always take the time to ensure they are following the instructions for cleaning the products to a tee, it has been advised.
Optometrist Dr Andrew Leitzel told Penn Live that it is "always wise" to carefully follow the directions on the bottle of contact lens solution, and to be aware that multi-purpose solutions and peroxide-based disinfecting solutions can have very different directions.
"Soft contacts versus rigid gas permeable contacts have different care regiments as well. So, my advice is to read the directions three times before use and if you are still unsure, ask your eye care provider," he added.
The expert noted that the type of solution people opt for matters, as not all solutions are created equally and so can have varying degrees of success.
When contact lens wearers find a solution that feels good with no problems, they should stick with it unless their eyecare provider suggests a change.
In some cases, eye irritation can occur if people change to a new contact lens solution just to save a few pounds, so staying with what works is best, Dr Leitzel noted.
As far as storage is concerned, the eye specialist recommended disposing of used disinfecting solution after lenses are inserted, than letting the case dry.
"Always add fresh solution to the case when storing your lenses overnight. Topping off the case is a bad idea because the diluted solution loses its ability to disinfect your lenses," he added.
Dr Lietzel also suggested cleaning the contact lens case at least once a week, with simple ways of doing this being to microwaving the case for a minute or boiling it for three minutes.
People should replace the case with every new bottle of contact lens solution that is purchased, while a good way to avoid wastage is by only using enough solution to cover the contact lens in your case, he concluded.
