II. 1.74 high index lens:
How High-Index Lenses Differ From Regular Lenses?
Regular glass or plastic lenses for high amounts of nearsightedness or farsightedness can be quite thick and heavy. Fortunately, chemists have created a variety of new "high-index" plastic lens materials that bend light more efficiently.
This means less material can be used in high-index lenses to correct the same amount of refractive error, which makes high-index plastic lenses both thinner and lighter than conventional glass or plastic lenses.
As the index of refraction increases, the curvature needed to produce a specific correction decreases. The result is a flatter, more attractive, lower volume, thinner lens than was previously possible.
Higher index materials have given patients, especially those with large refractive errors, freedom to choose lens sizes and shapes, as well as frame styles, that were once unavailable to them.
When these high index lens materials are used in aspheric, atoric, or progressive designs and paired with premium lens treatments, the value to you, the patient, expands dramatically.
Here are all the reasons why high index glasses are great:
High index lenses are thinner than standard lenses, making them more aesthetically pleasing and making your prescription seem weaker than it is. A thinner profile means a weaker prescription in general.
High index glasses are lightweight because of their thin lens profile.
High index lenses are denser than standard plastic or polycarbonate lenses, making them more scratch resistant. This is extremely useful for everyday glasses as it increases their lifespan and saves you money on a new pair in the long run.
Many people with strong prescriptions have to deal with the “bug-eyes” or “tiny eyes” distortion that comes from thick lenses. Thick, strong lenses can distort the way your eyes look to others, making them seem smaller or larger than they are. This is embarrassing and unattractive. High index lenses remove much of the eye distortion associated with high prescriptions.
In curved frames and some frames with special lens pockets, there is a limit to how thick a lens can be. High index lenses allow higher prescriptions to be inserted into many of these frames, broadening your frame options when you’re on the cusp.
III. Coating Choices:
As 1.74 high index lens, super hydrophobic coating is the only coating choice for it.
Super hydrophobic coating also name crazil coating, can make the lenses waterproof, antistatic, anti slip and oil resistance.
Generally speaking , super hydrophobic coating can exist 6~12 months.
