모듈러스란 단단함을 의미하는데요 모듈러스가 높을수록 더욱 단단하게 느껴져 착용감이 현저히 줄어들게 되는데요(하드렌즈를 생각하시면 될거 같아요)
Lenses are created from elements like glass or plastic and they are ground, polished, or molded for the needed condition. A lens can focus light-weight to kind an image, contrary to a prism, which refracts mild without the need of concentrating. Equipment that in the same way concentration or disperse waves and radiation other than noticeable mild are also called "lenses", for example microwave lenses, electron lenses, acoustic lenses, or explosive lenses.
In the situation of a camera a single would estimate the plate scale, which compares the clear (angular) size of the distant object to the dimensions of the actual picture developed at the main focus. The plate scale could be the reciprocal on the focal duration of the camera lens; lenses are classified as very long-focus lenses or wide-angle lenses according to their focal lengths.
뺄 때마다 너무 힘들어서 인공 눈물, 안약 등을 알아봤지만 렌즈를 낀 상태로 눈에 직접 넣지 말라고 하더라고요.
산소투과율은 말 그대로 렌즈 착용중 대기중에 산소가 투과되는 %를 의미합니다

Chromatic aberration is due to the dispersion on the lens content—the 렌즈 variation of its refractive index, n, Using the wavelength of sunshine. Considering the fact that, from the formulae above, f is dependent on n, it follows that mild of various wavelengths is targeted to diverse positions. Chromatic aberration of the lens is viewed as fringes of colour across the picture. It may be minimised through the use of an achromatic doublet (or achromat) through which two materials with differing dispersion are bonded with each other to type an individual lens.
the place M could be the magnification component described since the ratio of the size of a picture compared to the scale of the thing.
Near-up see of a flat Fresnel lens. A Fresnel lens has its optical area damaged up into slender rings, making it possible for the lens to get much thinner and lighter than standard lenses. Strong Fresnel lenses can be molded from plastic and they are affordable.
Net plastic neutrality is set up by obtaining credits from Plastic Lender®. A credit score signifies the gathering and conversion of 1 kilogram of plastic that may reach or be destined for waterways. CooperVision purchases credits equivalent to the burden of plastic in Awards
