Sample Contacts
The concept of contact lenses was first drawn in 1508 by Leonardo da Vinci. Three hundred years later technology advanced enough to actually have someone wear rigid contact lenses. We can only imagine how uncomfortable these sample contacts felt.
Thanks to technology again, the choice of contact lenses today would make the early inventors gasp in amazement. About 125 million people throughout the world are contact lens wearers. There are different reasons that people have for wearing contact lenses. They clearly carry benefits for a large global population. Now you can get sample contacts to see if they are right for you.
Contact lenses offer the following benefits:
- Won’t steam up
- Offer a wider field of vision
- More appropriate for sporting activities
- More effective for correcting keratoconus and aniseikonia
- Ultra violet protection more optimal
There are vision corrective lenses and cosmetic lenses available. For those individuals requiring corrective lenses contact lenses come in both rigid and soft lenses. The material of the lens, lens thickness, type of prescription, personal preference are all factors that determine which kind of lens they will wear.
Certain vision corrections can only be accomplished with the rigid lens since there are structural differences between soft and rigid lenses. Rigid lenses offer a more distinct field of vision than soft lenses. Rigid lenses too, do not contain any water since they are made from silicon polymers which actually are healthier for the eye. Soft lenses are made from water so the negative side to this is a tendency to dry out and become warped, reducing clear vision for the wearer. The soft lens will also draw moisture from the eye.
Cosmetic lenses are a fairly recent newcomer to the market. Fashion designers have popularized eye color as a fashion trend. By altering the wearer’s eye color, cosmetic lenses have become a fashion accessory thus creating a new market niche for the contact lens. It’s also fairly easy to get sample contacts if you want to try them out. You just have to go to the websites of the contact lens makers/manufacturers and request them.
Fortunately, technology continues to produce innovative sample contacts. Today there is a third type of lens on the market that is designed for patients having the following conditions of the eye:
- astigmatism
- hyperopia
- myopia
- post-surgical patients
- presbyopia
- keratoconus
The center of the lens is made of a breathable rigid material promoting the health of the cornea and providing high definition day and night vision. The soft outer skirt provides all day comfort. The new lens will not rotate as soft lenses tend to do. These lenses would truly have made Leonardo da Vinci’s day.
