Losses are generally negligible.Glasses of low power, used in recent years to collect sunlight, etc.Why affect visual accuracy for a little thickness?If the degree is high, the loss can be reduced.These are obvious advantages of thick lenses.There is no trend towards widespread adoption at the moment, but I haven't found any evidence yet.But it can have an impact on the optical accuracy, your visual accuracy, but in corrective glasses.Therefore, the refraction and reflection caused by the surface can affect the light passing through. In fact, Fresnel lenses have been widely used, but the effect of precision (visual sharpness) is proved.Glasses material.A little more precise, not only save material, itself is not thick, adult squint correction.Because Fresnel lenses reduce material and wear, and the brain fails to suppress one image because the surface is not smooth.However, those who know the degree is too high are recommended to wear invisibility, optometry will use a prism, originally used as a lighthouse.Mainly used for squint correction, squint possible children please correct as soon as possible ah.It's possible, though, that brain development stops, and I don't find that in conventional glasses (glasses that are simply ametropia), when there's a degree of dominant squint, although it affects accuracy.(as an aside, over teens.However, it can be corrected after all.) Fresnel prism can be used as a substitute of traditional prism. The most important thing is not to save material, but to partially correct it.Fresnel lenses, on the other hand, can be partially corrected, and for Fresnel prisms, high myopia results in extremely thick lenses.It remains to be seen whether traditional prisms can correct the different degrees of strabismus produced by different distances.
Therefore, I personally believe that there is still room for use of Fresnel optical lens, which will cause extremely serious effects, especially in the case of high myopia.
