Description

A kind of double light myopia campus learning training eyeglasses of flat-top and manufacturing method

Technical field

The present invention relates to the manufacture manufacture fields of resin mirror, more particularly to a kind of using the double light myopia campuses of 1.56 flat-tops Learning training eyeglass and manufacturing method.

Background technique

Due to study habit problem, Most students at school when abnormal sitting posture, many students swim at mystery in electronics Play, some students stay up late see TV, play mobile phone, online etc. extremely affects the health problem of child's eye development, be intuitive shape At one of the primary factor of myopia.And the common eyeglass worn all is largely that can only aggravate myopic degree, and it cannot be to view Power carries out improvement adjustment, and gradually carries out the recovery of eyesight.The glasses that student is worn when especially attending class are generally all than reality Border degree is big, and the letter written with chalk that teacher writes is all bigger, does not need the eyeglass for wearing lordotic and ADD at all in fact It practises and using.

Summary of the invention

For the deficiency of the above eyeglass, the object of the present invention is to provide a kind of double light myopia campus learning trainings of flat-top Eyeglass and manufacturing method are to use the monomer MY-55 of 1.56 refractive index for ontology, so that lens index is low, anti-blue light function More powerful, by weight, MY-55 monomer is 1000 ± 1.0 grams, and blue initiator is 4.2 ± 0.01 grams, and red initiator is 1.3 ± 0.01 grams, V-65 initiator is 2.0 ± 0.01 grams, and UB-60 release agent is 0.6 ± 0.05 gram, polymerizer 2.2 ± 0.01 Gram.

The technical scheme is that be accomplished by the following way: a kind of double light myopia campus learning training eyeglasses of flat-top And manufacturing method, comprising the following steps:

1) it, ingredient: under normal temperature conditions by 1000 ± 1.0 grams of MY-55 monomer, is filtered, is then placed in using 0.5 μm of Wire-wound filter core It is stirred under vacuum bucket, successively adds 0.6 ± 0.05 gram of UB-60 release agent respectively, 4.2 ± 0.01 grams of blue initiator, red causes 1.3 ± 0.01 grams of agent, being evacuated to and being stirred under vacuum pressure in bucket is -0.1Mpa, and stirring 20 minutes to being thoroughly mixed and place 24 Hour；Be added in the mixture after placing 24 hours 2.2 ± 0.01 grams of 2.0 ± 0.01 grams of V-65 initiator and polymerizer and It is stirred 5 minutes under normal temperature and pressure conditions, being finally evacuated to pressure in agitator again is that -0.1Mpa continues stirring 30 minutes；

2) it, molds: by AB mold according to certain thickness (1.2 ~ 2.3mm) requirement, using viscous with the matched adhesive tape of 1.56 monomers It is combined etc. to be cast；

3), be poured: the mixture for preparing step 1) before casting pours into teeming ladle and is evacuated down to -0.1 Mpa and keeps 30 Minute, then the material prepared is filled into the mold for getting togather mould, using clean pressurized with compressed air to 0.1 ~ 0.3MPa, during which There cannot be bubble generation；

4), one-step solidification: by pre-designed program, heat curing temperature curve is as follows: 26 DEG C keep the temperature 9 minutes, 33 minutes 37 DEG C are warming up to 42 DEG C of heatings in 42 DEG C and heat preservation 2.4 hours, 6.5 hours by interior 26 DEG C are warming up in 37 DEG C, 1.3 hours 51 DEG C are warming up in 67 DEG C, 2.4 hours in 51 DEG C, 4.2 hours and is warming up to 107 DEG C for 67 DEG C and keeps the temperature 50 minutes, 50 In minute 82 DEG C and constant temperature 1 hour will be cooled to by 107 DEG C；

5), secondary curing: being warming up to 117 DEG C and constant temperature 2.5 hours again, completes secondary curing；

6), die sinking, deburring, cleaning: coming out of the stove when being cooled to 20 ~ 25 DEG C, after eyeglass and mold separation, carries out to lens surface outer The repairing and cleaning of sight.

The present invention through detecting, refractive index be 1.552 have apparent anti-blue light effect, anti-blue light transmittance reach 80% with On, it is seen that luminous transmittance reaches 90%-93.4%, and 1.56 flat-top Bifocal lenses produced by the invention are according to student's optometry inserted sheet data Degree size control degree and ADD(+175) magnitude of size, eyeglass is consolidated in this study made to measure, when student can see clearly The blackboard word of Chu's blackboard can remove glasses, substantially reduce the probability that student deepens myopia degree.

Specific embodiment

Embodiment one
