Choosing contact lenses
Contact lenses provide the best physiological vision, approximate to that of people without sight defects. Contact lenses should be chosen by an ophthalmologist. If they are properly chosen, the patient is instructed how to take care of them and they can be a very safe form of correction.
In the case of cosmetic defects around the eyeball (e.g. corneal leucoma, loss or lack of iris, pathological cataract), we can apply a lens which restores the eye’s normal appearance. One specific type is the obstructive lens used to treat amblyopia (partial sight loss).
Types of contact lenses
Divided based on the material they are made from into:
Or based on their structure:
|Are contact lenses safe?
Yes. The greater their oxygen permeability and the shorter the time you wear them (frequently changed for new ones, worn for short times during the day), the safer they are.
|Can I choose my contact lenses myself?
This is very risky, as you can harm yourself by avoiding an ophthalmologist in this case. For example, you won’t feel at once that the lens is too tight.
