Frame Manufacturing
Manufacturing will differ depending on which material you use. The process for wood or metal isn’t the same but each of them needs to undergo inspection in order to be for sale. Every material has its own benefits so you should decide base on what works for you. Metal is lightweight but is prone to bending compared to wood. Rubber can withstand a lot of stress but it isn’t as comfortable as metal.
After inspection, the optometrist will use a machine to trace the structure and size of the frame. This part is very important because they need to adapt them to your prescription to fit the lenses. The next step is to make the lenses that will match the dimensions you desire.
Making the Lenses

They will use extreme force and heat to cut it according to your prescription.
The next step would be to polish with special tools that are used for different curvatures. After it’s fined and polished, they will need to unblock it by using the wax deblocking method. They will need to repeat the process if any issue occurs unless it was tinted which can be modified.
Some manufacturers will add special coating like anti-scratch or something that will add extra protection. There is also anti-UV and anti-glare coating that you can apply. This may increase the price but you will have a pair of glasses that you can wear every daily on every occasion.
