Dr. William Boothe, one of the world’s top eye surgeons, provides a quick analysis of the pros and cons of contact lenses.
It turns out that contact lenses are much better than glasses. The lens in glasses is a massive optical medium, which creates some distortion. For example, between the eye and the glasses is the air and a few centimeters of space and this is another medium which along with the glasses lens, refracts light. The light is then refracted on the cornea itself. In total we have three refractive mediums compared to to contact lenses, which create only one refractive medium. Contact lens and the eye bond together to create a single entity, essentially enhancing the retina to create one medium refractive index and as result it has only one distortion point.
If the severity of nearsightedness is not more than five diopters, the contact lens is definitely the better option. In addition, contact lenses provide a wider field of view in comparison to glasses. The cornea has a spherical surface and the glasses has flat one. This means that the image distortion is inevitable.
A con about contact lens is each individual user’s ability to comfortably wear contact lenses. Certain people have a steep cornea, while others have a flat cornea. This changed the position in which the contact lens sits on the eye and has a great effect on user comfort.
At Boothe Eye Care Center we receive many parents who inquire whether or not their child can wear contact lenses. The answer to that is “yes”. Children whom are taught good hygiene habits especially after playing or eating, and wash their hands after such activity can wear contact lenses.
After the age of forty, someone who has never used contact lens before, are advised not to switch because of the adjustment period that would accompany such a drastic switch.
Although contact lenses allow you to partake in your favorite activities and hobbies or sports, certain care should be taken when swimming with contact lenses whether it is a pool or ocean.
