Virtually anyone can put on contact lenses, if they want to. There is an additional part of an eye exam that must be done in order to consider the use of contact lenses. The optometrist will certainly assess the type of contacts, just how they are positioned in eye, exactly how the eye contacts reacts to blinking, and just how much movement there is on eye.
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.
However, patients usually find soft contact lenses really feel much more comfortable sooner compared to the time it takes to adapt to hard contact lenses. Soft contact lenses are not for everybody: a person with a risked cornea, for instance in the case of keratoconus or a bad medical experience or injury, could not be a prospect for soft lenses due to the fact that they will merely mold to the eye's irregular shape, and not provide the vision adjustment required. Conversely, a hard contact could actually lend stability 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.
