H3 contact lenses are spherical lenses from Bausch and Lomb designed to correct the vision of patients suffering from hyperopia and aphakia. The lenses are manufactured using "spin-cast" technology and are designed as daily wear lenses to be replaced after up to one year of use.
Lens Material
The lens material (polymacon), is a hydrophilic polymer of 2-hydroxyethyl methacrylate, and is 38.6% water by weight when immersed in saline solution. These lenses are hemispherical flexible shells.
| Lens Parameters | |
| Chord Diameter: | 13.5mm |
| Center Thickness: | 0.47mm to 0.59mm |
| Base Curves: | Median |
| Powers: | +6.50D to +20.00D (in 0.50D steps) |
Lens Properties | |
| Specific Gravity: | 1.12 |
| Refractive Index: | 1.43 |
| Surface Character: | Hydrophilic |
| Water Content: | 38.6% |
| Oxygen Permeability (Dk): | 8.4 |
| Oxygen Transmission (Dk/t): | 1.6 |
