A new type of contact lens made mostly of water is providing an alternative option for those who get dry, scratchy lenses after a long day.

Kristy Mouton sits in front of a computer most of the time at work. She said she doesn't know what she'd do without her contact lenses.

She has relied on contacts for 20 years, but there's also been a downside.

I've had a lot of problems with the dryness, not really irritation, but by the midday getting dryness in the eyes, she said.

Contact lenses have come a long way since their invention in the 1950s, said optometrist Melvin Gehrig.

The newest development is a two-part lens called Total 1.

The inside lens is made out of silicone, which creates the oxygen permeability that we want in a contact today, and the outside of the lens is a type of hydrogel that when it touches the eye you're almost touching 100 percent water, Dr. Gehrig said.

The water-gradient lenses mimic the cornea's fluid, making them comfortable to wear all day.

The added comfort does come with a price tag, however. A month's supply of these lenses will cost you around $60 -- about three times as much as standard daily contact lenses.

For now, the Total 1 daily lenses only correct near-sightedness, but lenses that correct astigatism and bifocal vision are in production.
