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 many contact lens options available to patients depending on their lifestyle, occupation and personal needs, such as physical disabilities or an irregularly shaped cornea. Contact lenses can be divided into two main categories: soft lenses and hard lenses. Hard contacts are more rigid in design. They will not fold over themselves, and can actually break if a fold is attempted. Hard lenses are more durable, easier to clean, and are made from a material that is more breathable as well. Soft contacts are flexible, can be rolled up, and may be harder 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 assessment, optometrists will aid their patients in choosing the best contacts for their eyes and the best ways to wear and care for them.
