1,61 vs 1,67 index


Oct 31, 2013 · It depends. Generally, the 1.60 index lenses are thinner than 1.50 index lenses. That is to say, if you have strong prescription, 1.60 index lenses is highly suggested. However, if you have low prescription, 1.50 index lenses are enough. But if you have strong prescription and use 1.50 index lenses, the lenses look much thicker than 1.60 index

1.67 index of refraction lenses will be about 8% thinner than 1.60 at this power, assuming both are finished lenses (off the shelve with 1mm center thickness) with the same surface design (spheric, aspheric, etc.). Sep 15, 2009 · The thing is, I'm torn between the 1.61 and 1.67 high index range. My right eye is still safely in that "1.61 is fine" range, but the left eye obviously requires a thicker lens. Because they wouldn't be my day-to-day glasses, however, I'm leaning towards getting the cheaper 1.61 optionbut I'm concerned that will impact how well I can see out See full list on zennioptical.com If you have a mid to high prescription, stick to the thinner lens options at 1.67 index and 1.74, which is the thinnest and lightest of the two.

Buy the 1.61 lenses. The 1.67 and 1.61 are a numerical " index of refraction " of the lenses. What this means is that light rays travel at 186,000 feet per second and the higher the "index" of lens you wear the more the light rays will be slowed down.

Difference between 1.61 & 1.67 High-Index Lenses - YouTube The High-Index Lenses are worthy for people with refractive orders such as Nearsightedness, Farsightedness & Astigmatism. A high-index has

Conventional plastic lenses have a refractive index of approximately 1.50. For glass, it's 1.52.

1,61 vs 1,67 index

This means how much the light that enters the lens is refracted (bent) as it passes through the lens. Lens Index is also related to the thickness of the lens. The higher the index, the thinner the lens will be. Apr 10, 2012 Aug 30, 2013 Higher index plastic also has a higher amount of chromatic aberration.

Good choice for extra-strong prescriptions.-7.00 to -9.00 or +7.00 to +9.00-3.25 to -4.00 or +3.25 to +4.00: 1.74 INDEX LENS Favorite Answer The 1.61 is best for that power. The 1.67 is for use with powers over - 6.00 I don't know how Frank, calculates that, but it is 13% difference in thickness between the 1.61 and the Once you get close to -5.00 diopters, moving the index higher to a 1.61 is a good idea, if it fits your budget. From there, if you have a prescription over -6.00 diopters, a 1.67 high index lens is a worthwhile upgrade. The Lens Index number (1.50, 1.57, 1.53, 1.59, 1.61, 1.67, or 1.74) refers to the degree of refraction the lens provides. This means how much the light that enters the lens is refracted (bent) as it passes through the lens. Lens Index is also related to the thickness of the lens. The higher the index, the thinner the lens will be.

Salaire de 5,67%. 1,220 F. 5,54%. 11,30%. 9,42 F. 13,63%. 1979. 1,0400 F. 4,00%.

1,61 vs 1,67 index

The resulting number (1.5, 1.6, 1.67, 1.74) is referred to as the “index.” The higher the number, the more light is slowed down or bent. This means high-index lenses bend light at steeper angles than standard-index, hard resin lenses. Jan 07, 2012 · However, if your frame is big (like the popular raybans) 1.67 will be better. 1.61 has better optical clerity but 1.67 is aspheric, standard 1.61 are spherical, so overall they are the same, just 1.67 is a tiny bit thinner. Apr 07, 2009 · Polycarbonate lenses are quite inferior optically in a power like that, compared to the 1.61 or 1.67.

Higher prescriptions with SPH correction +6.25, – 6.25 to +8.00, – 8.00 and for CYL correction +3.25, -3.25 and +4.00, -4.00, 1.67 index lenses are highly recommended. 1.61 index is ideal for power less than -4.00, 1.67 is ideal for power less than -6.00, 1.74 index is ideal for power less than -8.00.
