Tips for choosing contact lenses

1. The material
Contact lenses can be made of different materials. For example, PMMA, which we can say are the oldest and are losing popularity for not allowing the passage of oxygen to the eye. Nothing recommendable.
On the other hand, there are the gas permeable ones, which, although they are much better than the PMMA ones, are not as soft as the silicone ones, so it will cost a little more to adapt to them. However, they offer a much sharper view.
Gel lenses are commonly known as soft lenses that adapt easily and quickly to the eye and offer great comfort. You won't even know you're wearing them!
And the latest in contact lenses are those made of silicone hydrogel that allow the passage of oxygen to the cornea and are very comfortable to wear because they adapt perfectly to the eye.
