Example Embodiment

[0040] Example one

[0041] The present invention is a processing technique for producing special lenses for safe driving. The processing technique includes the following steps:

[0042] (1) Process semi-finished resin products into resin substrates or subject resin substrates to visual inspection, pretreatment and fixtures;

[0043] (2) Add 0.08% VL462 to the top coating hardening liquid MP7110 of SDC, stir it fully until it is completely dissolved, add it to the hardening liquid tank in the hardening machine, and circulate it with a 5μm filter element for 24h;

[0044] (3) The lens is hardened and coated by an automatic hardening machine, and the pulling speed of the solution in step (2) is set to: 1.5mm / s, and after the pulling is finished, it is placed in an oven at 115°C for 2.5h;

[0045] (4) The lens cured in step (3) is transferred to a vacuum coating machine to be coated with a 585nm narrow-band visible light reflection coating.

Example Embodiment

[0046] Example two

Abstract

The present invention is a processing technology for producing special lenses for safe driving. The processing technology includes the following steps: (1) processing the resin semi-finished product into a resin substrate or subjecting the resin substrate to visual inspection, pretreatment, and clamping; (2) Add 0.01%-5% additive to SDC’s top coating hardening solution MP7110, stir until completely dissolved, then add it to the hardening solution tank in the hardening machine and circulate it with a 1-10μm filter element for 24 hours; (3) The lens is hardened and coated by an automatic hardening machine. The pulling speed of the solution prepared in step (2) is set at 1.5mm/s. Step (3) The cured lens is transferred to a vacuum coating machine to be coated with a 585nm narrow-band visible light reflective coating layer. The invention can keep driving safe and comfortable all the time during the day and night, and protect the eyes in all aspects.

Description

technical field [0001] The invention relates to the technical field of lens manufacturing, in particular to a processing technology for producing special lenses for safe driving. Background technique [0002] Lenses used in daily life can not only correct vision and protect eyes, but also serve as decorations. There are three common types of glasses, namely myopia glasses, farsighted glasses (reading glasses) and sunglasses (sunglasses). In addition to these types of glasses, there are also sports goggles, TV computer goggles and driver goggles. [0003] Resin lenses have very complex cross-linking and conjugated bonds inside. Although polycarbonate lenses can block harmful UV light, most resin lenses with other structures cannot block harmful ultraviolet rays, and the damage of ultraviolet rays to glasses cannot be underestimated. At present, the mainstream anti-UV lenses on the market can only block ultraviolet rays in the lower band of 100-400nm, which is far behind the...
