You may be surprised to learn that the Italian inventor, artist and scientist Leonardo da Vinci is credited with describing and sketching the first ideas for contact lenses in 1508! But it was more than 300 years later before contact lenses were actually fabricated and worn on the eye.
Highlights in Contact Lens History
1508 Leonardo da Vinci describes and sketches the first ideas for contact lenses.
1632 French mathematician Rene Descartes suggests placing a lens directly on the eye to correct vision.

Contact lenses history is still being written. As long as contact lens wearers have regular eye exams, dispose of contact lenses as prescribed, keep contacts clean, and take care of their contact lenses and overall eye health, contact lenses can be a joy to ears- especially when compared with the alternative- eyeglasses. If the history of contact lenses is anything to go by we can expect even more exciting and sometimes wacky developments.
HOW DOES CONTACT LENSES WORK??
The 1980s only offered so much in terms of eyewear fashion. Today's junior high students walk around in invisiline braces and colored contact lenses and display their school photos proudly.It is only relatively recently however that the popularity of lenses really took off, they did not become mass marketed and affordable until the Generation X crowd were heading to college. The developments made have been astounding in a range of ways.
Leonardo da Vinci considered the contact lens back in 1508 suggesting that a lens could greatly improve vision if applied directly to the eye.
In the 1820s, English astronomer John Herschel considered fitting a lens to the eye and in 1887 a glass eye maker, F.A. Muller, fitted an eye with the first glass contact lens. In 1888, A.E. Zurich, a physicist, made a pair of glass lenses to correct his own vision and coined the term "contact lens.
In the 1900s, the contact lens science went into high gear with many chemists, physicians, and engineers trying out different materials to make a comfortable, corrective lens. Plastic contact lenses were invented in 1938. In 1947, the first contact lens made of plastic that covered only the cornea was invented by American Kevin Tuohy. Throughout the history of contact lenses, constant advancements have been made.
Well, I just browse 1 of the shopping blogs and it's currently selling 18.7mm lens..??!OMG.. i mean 14.5mm lens already makes my eyes looks bigger, so what about 18.7..OMG..I seriously want it..but it's expensive.. so,I'll just wait for the price to low down first(LOL, it won't happen though)
At first, I really hate contact lens, and I'm comfortable wearing spectacles.. But, I only put it on while studying because I think I really looks like a nerd, and moreover, a GEEK????LMAO...my mummy always scold me when I'm not wearing it, and I always ignored her all the time.. she says my eye's degree will continuously increasing minute by minute, until I go completely blind??? I know it's true, but what's with degree increasing minute by minute,,LMFAO..that's totally lying mum..sorry,I'm not a kid anymore..
so, my friends suggested me to wear lens since I'm so stubborn by not wearing spectacles while I'm out with them, pretending my vision is super clear, but the truth is it's super blur..I can't even see people's face who's standing only 5 meters away from me...my degree is 150/300, for R/L.. and seriously why my left eye is so fuckin damaged compared to my right eye..?The optometrist says that it's unlikely case but I didn't need to worry because it wont affect my body,, but he didnt tell me why did the thing happens???Do I look really dumb that he thinks I've could never understand even if he ever did explained it to me..so, he never explained though..urgh..and I just hate that shemale-look optometrist..! okay, back to the topic, so, i said to my girls that I really like the original colours of my eye that I wont wear any contact lens, but they still forced me to wear the clear lens..so, when I wear it for the first time, I was like, OMG..this was soooo clear..(my vision)
I never thought it would be so clear like this..and I'm in greatest tear ever, since it was my first time wearing lens, and my eyes hurts a lot!!!!
Since then I got very fanatic to contact lens...i tend to collect all the colours available,so now,i have black,blue,grey,brown,red,violet,and pink,..the only one left is green, so i'm gonna complete my collection with the BLYTHEYE-series soon..\(>//<)/
