- 摘要：
- <p>A manufacturing method of plastic lens includes the steps of: preparing a first liquid containing at least one metal oxide and a second liquid containing at least one organosilicon compound; manufacturing a hard coat liquid by mixing the first liquid and the second liquid so that the mass ratio of the solid content of the first liquid to the solid content of second liquid falls within a range of 45/55 to 65/35; and coating the hard coat liquid on a plastic lens substrate to form a hard coat film and then curing the hard coat film.</p>
