Contact Lens Examination
There are many situations that confuse our patients about contact lenses and contact lenses. In general, we should be asked to use a lens, what should we pay attention to when buying a lens, such as whether the lens needs to be examined separately. Here are the answers to your questions;
What is a Contact Lens?
Contact lens is the apparatus that settles on the cornea which is the anterior part of our eye, temporarily eliminates the refraction defect and provides clear vision during the time it is worn. Contact lenses were made of glass in the 1800s, when they were invented, and now with advanced technology, they are produced from materials that will cause the least damage to the cornea.
Contact lens has become widespread and preferred by people all over the world thanks to the cosmetic use of those who want to change eye color, the use of those who do not want to wear glasses to remove refractive errors, and the therapeutic use in some eye diseases.
The cornea structure of each person is different from each other. The structure of your eye changes according to the refractive error that occurs in the eye, and the size of the lens you need to wear will change according to the size of your eyeball. If it is not appropriate for your eye, it will scratch your cornea as it moves on your cornea and possibly cause irreparable eye disorders.
So even if you use it for cosmetic purposes, you need to be examined to get a lens.
How Should a Contact Lens Be?
The contact lens is designed to fit on the cornea. If the cornea is fed with oxygen and you do not remove your lens for a long time, there will be thinning and scratches on your cornea due to lack of oxygen.
- It should not stick too tight to the cornea.
- It should not be too loose.
- It should be well centered and wrapped around the cornea.
- The tear should move very lightly in order to clean the eye easily.
- The wearer should be able to move and see clearly, not to feel the lens.
- After blinking eyes, it should not blur your vision.
- The edges of the lenses should not put pressure on your eyes.
- Never sleep with contact lenses in your eyes, never swim in the sea or in the pool.
