Semi Finished Lens:
The definition of a semi-finished lens
Semi-finished lenses is the most primitive state of the lens, the customer can buy finished semi-finished lenses according to the required degree of finished lenses to polish, so only semi-finished lenses camber, there is no degree. Different prescription powers request for different semi-finished lens types or base curves.
The importance of a good semi-finished lens to RX production
1. Semi-finished lenses need to have high qualified rate in power accurancy, stability and cosmetics quality.
2. High optical features, good tinting effects and hard-coating/AR coating results, realizing the maximum production capacity are also available for a good semi-finished lens.
3. Semi finished lenses can reprocessing to RX production, and as semi-finished lenses, not just superficial quality, they are more focus on the internal quality, such as precise and stable parameters, especially for the popular freeform lens.
4. Freeform lab requests for high quality of semi-finished lenses in precise and stable base curves/radiusg/thickness. Unqualified semi-finished lenses will lead to much waste in capacity, labor, clicking charge, delivery postpone, the consequence of which will be more than the semi-finished lens cost.
Coating Choice
AR Coating
It also can be named as hard multi coated, that means coating an anti-reflective film on the hard coating lens, can protect the lens effectively from reflection and glare, enhance functional and charity of your vision |
Hard Coating
It also can be named as anti-scratch coating, the function of this coating is to protect the surface of the lenses from impact and scratch reisitance. |
