Overall Overview of How Contact Lenses Work For Eyes

Extracted Observation

Well-known, mathematician and creator Leonardo da Vinci (1452-1519) proposed the idea of the first known sketches in 1508 that redirected the optics of the human eye could be discerned by placing the cornea directly in contact with water.

In 1827, English astronomer Sir John Herschel proposed the idea of making a mold of eyes; Such molds would enable the production of corrective lenses that could conform to the front surface of the eye.

In 1936, New York optometrist William Feinbloom in 1904-1985 introduced scleral lenses made of a combination of glass & plastic that were significantly lighter than older glass-blown contacts.

 

“The history of contacts and the improvements they hold for our future are fascinating subjects since many of us have some form of vision problems.”

Eyeglasses Or Contact Lenses?

Compared to eyeglasses, contact lenses are a closely & relatively modern invention. Glasses were invented 700 years ago (in Italy), and the case of gemstones being utilized for magnification has been documented as far back as the 1st century; In contrast, contacts that cover only the cornea have existed for just over 60 years. But the concept of contacts has its long history.

 

How Do Contacts Work Indeed

Contact lenses are small prescription contact lenses; worn with the eyes; They are crafted to fix the refractive errors and maintain ocular health. They float on the tear film layer on the surface of the cornea.

Today, even nowadays, contact lenses are a far cry from da Vinci’s initial exact concept of contact lenses. For the extended majority of lens wearers, these contact lenses are very comfortable and often unnoticeable, allowing people to live their lives freely with excellent vision; The modern contacts are much more than the traditional small eyeglasses enough worthy to fit into the eyes.
