Choosing Contact Lens Solution for Sensitive Eyes

It is important that you know about the various types of solutions available in the market for contact lenses. The reason is that there are so many varieties and all of them are suitable for altogether different tasks, eyes characteristics, and types of contact lenses.

Moreover, a certain preservative known as thimerosal used in a saline solution can result in at the least irritation, itching, or burning in sensitive eyes. At worst, with prolonged use you can grievously harm your sensitive eyes. Knowing about the different types of contact lens solutions given below can help you make the correct choice for sensitive eyes.

Eye drops
These are used to moisturize the eyes because of complaints of dryness of eyes by users of contact lenses. They are also known as rewetting solutions. An important characteristic of a rewetting agent is that it should not stain the sensitive eyes or the contact lenses.

Saline solution
It is a salt solution used to simply rinse and store the contact lenses after they have been cleaned and just before they are to be inserted in the eyes. It is usually used after the contact lenses have been disinfected using ultraviolet rays for the purpose.

A saline solution is also used with enzymatic cleaning tablets. It generally contains a preservative known as thimerosal to prolong its shelf life unless marked thimerosal-free for sensitive eyes. When so marked, the product will have an expiration date.

Enzymatic cleaning tablets
These are used to remove protein from contact lenses. Protein removal from contact lenses is usually undertaken once per week. The tablets are used in conjunction with saline solutions, so for sensitive eyes you need to be careful about which saline solution to use.

Hydrogen peroxide solution
This is a very effective disinfectant for killing bacteria and other micro-organisms from contact lenses. In practice a hydrogen peroxide neutralizing tablet is used in conjunction with the chemical. It becomes important to add the neutralizing tablet directly as part of the solution or separately. Otherwise, if you forget, your eyes can be damaged by the corrosive hydrogen peroxide solution after you insert the contact lenses in them. It also becomes mandatory to rinse and store your contact lenses in saline solution thereafter and before they are inserted in your eyes.  

Multi-purpose solution
This is the all-in-one solution for contact lenses that is so popular in the eyes of people because it is so convenient to use. It can be used not only to clean the lenses, but to also rinse, disinfect, and store the lenses.

It has been found to be effective against fungi, acanthamoeba, and bacteria. However, the multi-purpose solution is not recommended to be used for people whose eyes are inherently sensitive and allergic to preservatives such as thimerosal used in contact lens solutions.

People with sensitive eyes need to be extremely careful about the contact lens solution they use. Sensitive eyes can be easily aggravated through itching, burning, reddening, or tearing by foreign objects or certain preservative agents such as thimerosal in contact lens solutions. Therefore, you need to use an essentially preservative-free contact lens solution. You can use the neutralizing tablet with hydrogen peroxide disinfectant discussed above with the procedure already outlined even for sensitive eyes.

An important aspect worth knowing about sensitive eyes is that an allergic reaction can flare up even after you may have been using a certain product without any issues. You can use saline solution that is especially marked thimerosal-free for sensitive eyes. However, preservative-free products will be bound to have expiration dates and therefore you need to use such products before they expire.
