Throughout the day, your eyes are constantly exposed to dust, dirt and pollution particles. These affect the tear film the watery substance that has a lubricating but also protective function which can cause the annoying sensation of dryness.

Environmental factors can negatively affect the contact lenses hydration which is when the lenses draw on the tear film to restore lubrication. Luckily, there are now different types of lenses to overcome this problem. Lenses with low water content The most common mistake people make which leads to eye dehydration is thinking they should go for a lens with a high hydration rate. If you do this, the lens will tend to hydrate the eye, giving it all the liquid that it contains in a short amount of time. Consequently, the dryness of the contact lens will be added to the dry eye, which means it could lose its initial geometric characteristics and cause damage to the cornea. The advisable solution is to opt for soft lenses with low water content, designed precisely to retain water, maintaining the right balance between the lens liquid and that of the eye.

Daily lenses require minimum levels of maintenance, and are easy to use.

It’s also worth noting that as well as wearing the right contact lenses for your eyes, eye drops can also be a good way to keep your eyes hydrated.
