Tangible Science Frequently Asked Questions

What care solutions are compatible with the Tangible Hydra-PEG coating?

The following contact lens care solutions will not damage the Tangible Hydra-PEG coating:

Tangible® Clean, Boston Simplus, Unique PH, Clear Care, and Clear Care with Hydra-Glyde. 

Any care solutions not listed above should be considered incompatible with the Tangible Hydra-PEG coating and will run the risk of damaging or destroying the coating.

Can I store lenses coated with Tangible Hydra-PEG dry in their case?

Never store coated lenses dry. The process of dehydrating and rehydrating the coating may damage or destroy it.

Are wetting drops and artificial tears compatible with the Tangible Hydra-PEG coating?

Wetting drops and artificial tears should not damage the Tangible Hydra-PEG coating. However, please consult with your practitioner to ensure that those products are safe to use with contact lenses.

Is it safe to clean Tangible Hydra-PEG coated lenses with tap water?

Never rinse or rub your Tangible Hydra-PEG coated lenses with tap water. Water alone does not offer the benefits of surfactants and lubricants contained in contact lens solutions which could damage the coating. Additionally, exposure to tap water may increase the risk of eye infection or irritation.

How does an eye care practice benefit from prescribing lenses with Tangible Hydra-PEG?

A practice benefits from increased patient satisfaction from an improved lens wearing experience, reduced chair time per patient by spending less time troubleshooting patients and more time fitting new patients, and a competitive advantage by offering the newest technology to patients. 

Are contact lens insertion/removal tools safe to use with the Tangible Hydra-PEG coating?

It is safe to use the suction cup-style insertion/removal tools with coated lenses. However, during use, try to minimize the force placed upon the coated lens by the tool, to avoid damage.

How long should the Tangible Hydra-PEG coating last on the lenses?

While the coating is permanently bonded to lenses and designed to last the lifetime of the lenses, various factors may impact the durability of its benefits, including:

A patient’s tear composition (i.e. heavy depositors), use of incompatible cleansers or rewetting drops, vigorous rubbing of lenses during cleaning, use of tap water, storing lenses dry or without compatible solution.

The use of compatible solutions and care will ensure long-lasting benefits for coated lenses.

Is sterile saline compatible with Tangible Hydra-PEG?

It is safe to rinse coated lenses with sterile saline, but patients should avoid rubbing coated lenses with saline. Rubbing a coated lens with pure saline that does not contain any surfactants or lubricants may damage the coating.

Can coated lenses be rubbed during cleaning?

Lenses coated with Tangible Hydra-PEG can be rubbed with multi-purpose solution during cleaning.

Can I fill my scleral lens with Tangible Clean?

How large is the Tangible Boost lens case?

The lens case that is included in every box of Tangible Boost has a 23mm diameter, and an 8mm depth.

Can I use Tangible Boost on my non-coated lenses?

Tangible Boost is intended for rigid lenses that were coated with Tangible Hydra-PEG when they were made. If you are not sure that your lenses were coated when they were manufactured, check with your practitioner. 

Why am I getting deposits on my lenses if am using Tangible Boost?

Tangible Boost is meant to prolong the peak performance of the Tangible Hydra-PEG coating. One of the benefits of Hydra-PEG is that it will help lenses be more resistant to deposits building up on the lens. However, it will not cause a reduction in the amount of protein and other lipids your eye creates. Tangible Boost works best when it is used from the beginning of new lens wear. If your lenses were older when you started using Boost, or, you have not used Boost consistently, your results may not be as significant. Make sure your practitioner is aware of any new symptoms you experience with your eyes or contact lenses. 

Why do I have to enter my practitioner's information to purchase Tangible Boost?

Since Tangible Boost is a prescription product per the FDA, we must verify that each patient who orders Tangible Boost is doing so with a valid prescription from a practitioner eligible to prescribe it. This process allows us to be able to offer online access to purchase Tangible Boost and is usually very fast. 

What if my lenses feel dry or sticky when I am wearing them?

Lenses feeling dry or sticky is usually a sign of decreased tear production or quality. This can be caused by many things such as being in a different climate, adjusting to a new medication, lacking sleep, or suffering from allergies. Consider adding a rewetting drop to your daily regimen. Any drop that can be used with contact lenses is compatible with the coating, however, a lot of practitioners want their scleral lens patients to use preservative-free drops so it's best to check with them.

How do you store lenses with Hydra-PEG for longer than a few days?

Hydra-PEG coated lenses must be stored wet using one of the compatible multi-purpose solutions. It is important to remember to change the storage solution every 30 days and to be mindful of the expiration date of the solution. Each time you change the solution, clean the case as well. This is for ANY of the solutions you choose from the approved list. 

Can prescription eye drops be used with Hydra-PEG lenses?

Prescription eye drops should always be instilled prior to inserting contacts or after removing contacts. This is true for any type of prescription eye drop to ensure your eye is receiving the full benefits of the drop. Speak to your practitioner about the preferred timing of using any prescription drops as there will be specific recommendations based on the type of drop and your specific ocular health and history.
