[0021] After adopting the above scheme, the equipment of the present invention has a simple structure, a simple production process, is convenient for processing and manufacturing, and has a low processing cost.

[0022] The present invention adds special process treatment before and after dyeing and strengthening of nylon lenses. Annealing treatment can eliminate stress and fix color. Acid-base neutralization and plasma ultrasonic cleaning make the dyeing liquid and nylon lenses closely combined. Then a layer of bridging agent is applied on the surface of the lens. The bridging agent can well protect the dyeing liquid. During the strengthening process, the strengthening liquid and the bridging agent are well and closely combined to prevent any contact between the strengthening liquid and the dyeing liquid. The finished nylon dyed and strengthened lenses and samples made in this way have no color difference and will not fade.
