Essentially anybody can wear contact lenses, if they are willing to try it. There is an added part of eye exam needed to consider wearing contact lenses. The optometrist will use things like the types of contacts at hand, the way the eye reacts to blinking, how the contact is placed in the eye and the amount of movement the eye makes.
Incorrect contact lens use can seriously damage the eye or the contact lens. Removing or moving the lens incorrectly, excessively rubbing their eyes or other errors can cause some problems in the eyes, especially if they have a weak retina. This could trigger a tear, detachment of the retina, lead to the lid catching on the contact and cause an abrasion to the eye. Also, poor hygienic practices put a patient at risk for developing severe infections. Washing hands before inserting and removing contact lenses, rinsing them in appropriate disinfecting contact lens solution, and following the contact lens changing schedule are all part of taking care of the contact lenses and taking care of the eyes that wear them. Good habits and training are very important to go over during an eye exam with a contact lens patient.
There are several contact lens choices offered to patients depending on their lifestyle, profession and personal necessities, such as physical disabilities or an irregularly shaped cornea. Contact lenses can be divided in to two first groups: soft lenses and tough lenses. These types of tough lenses are firmer in nature and will not fold up on themselves, they may even break if a fold is attempted. Hard lenses are much more resilient, easier to wash, and are made from a product that is more breathable too. Soft contacts are versatile, can be rolled and bent but people may find them more challenging to work with.
On the other hand, many people will say that the time it takes to adjust to hard contacts is not worth the ease of putting them in. Soft contact lenses are not for everybody: someone with a jeopardized cornea, for example in the case of keratoconus or a bad medical experience or trauma, might not be a prospect for soft lenses since they will just comply with eye's uneven shape, and not supply the vision correction required. Alternatively, a hard contact could really provide security to a cornea.
In addition to a contact lens evaluation, eye doctors help patients navigate the vast array of contact lens choices and teach them how to properly use their lenses.
