Fivealive said@Deco....They had lenses in 1965?! I didn't know that!!
Yes, the hard plastic kind. Soft lenses didn't become widely available until a few years later, and I got my first pair of those in 1972.
It was quite the process to own soft lenses, besides daily cleaning you had to sterilize them each day in a small electric autoclave aseptor. Later all-chemical cold methods were developed, but many of these contained a mercury solution (thimirasol) that caused eye irritation, as they did to me, and has been blamed for other health problems.
But the hard lenses were more difficult to wear. Any jolt to the head could dislodge them, so they'd slip onto the white of the eye, and if they went under your upper eyelid it could be a hassle to get them out. For that reason I rarely wore them during high school gym class. In fact, they could even pop right out of your eye.
Plus they were normally tinted grey, because due to some optical property that I don't understand the lenses would make the eyes more sensitive to light. But that meant your eyes appeared a bit darker, and people could see the tinted lens on your eye.
