1.74 high index lenses gain the designation as the thinnest lenses available for purchase in america under current regulations. They are easily considered the ultimate in lightweight lens technology and provide unparalleled clearness and sharpness along with incredible durability. Last, you may even want to avoid substantial index lenses for the first couple of glasses…
High index lenses create that significantly thinner edge we discussed above which means you can fit your lenses in any frame you like. High index corrective lenses bend light better than standard lenses, enabling a thinner, lighter lens option. This makes it easier to fit them inside regular frames and opens up a wider collection…
Most high-index lenses happen to be aspheric in design, this means the zoom lens is flatter. High-index lenses include a refractive index above 1.50— which range from 1.53 to 1.74. A high-index lens could be recommended if your optical prescription is on top of 2.00 diopters. The lens index chart ranges between 1.5 standard index…
Transparent amorphous silicon has the benefit of producing hologram devices or ultra-thin lenses which are one thousandth of the thickness of conventional lenses at a fraction of the price. The applicability of the silicon has also been expanded in that the amorphous silicon, which includes been used only in thermal infrared cameras, is now able…
Colors containing only one wavelength are also called pure colors or spectral colors. This the contrary of everything you see in light emitting diodes in which electricity causes emission of light.

This means “spherical error;” it represents how nearsighted or farsighted you are. Kyra is really a freelance writer based in California who focuses on copywriting and article writing. She…
It is extremely strong, very light, and resistant to scratches and breaking. The patient’s prescription is +0.75 OD, +4.25 OS, PD is 65. The patient picked out a zyl frame and had eye exam. These are two very different lenses and two completely different powers. The patient’s prescription is -8.00 R –7.75 L and the…
The next term on your own prescription is Sphere and is are measured in diopters . This number lets you know how strong your lenses have to be to correct your vision. If this number has a minus sign (–), you are nearsighted; if the number has a plus sign (+) or isn’t preceded by…
The curvature in a minus lens will get gradually steeper toward the periphery and an advantage lens curvature will gradually flatten toward the periphery. This is important because it provides consistent optical clarity in the lens periphery, not just the center. It also allows for someone with a strong prescription to wear a larger collection…
This can be a great option for those who have severe myopia that cannot be treated by LASIK, researchers say. someone’s myopia progresses until they need −5 dioptres or even more of spherical correction,1,2 even though definitions used to grade myopia are variable. The contrary of myopia in English is hyperopia (long-sightedness). A recent review…
