People who wear glasses will tell you how annoying it is to wear them around. Glasses are bulky and expensive. They can fall off easily and get damaged. Almost everyone who wears corrective glasses is bound to complain about them
Contact lenses were not different in the start. They had a lot of problems.
Initial problems with contact lenses
Da Vinci was the first person to suggest that human vision can be altered by placing the cornea directly in water. However, this idea was very impractical. The first contact lens was made in 1887 from glass and fitted over the entire eye.
These initial contact lenses were quite irritable as they did not allow much oxygen to pass through them. This meant that the oxygen-carrying tears could not pass under the lens and on the cornea. This resulted in dry eyes. Additionally, contact lenses were hard to take care of and caused frequent damage to the eyes.
Technological improvements
Technology has been improving at a rapid pace. This is because one technological advancement aids in the development of the other and the chain keeps growing. We as a species have evolved enough to fix and enhance our vision quite literally.
