Why are my contact lenses foggy when I wear them? What should I do if my contact lenses are always slippery when I wear them?

I wanted to wear colored contact lenses to create a different look, but after putting them on, they looked foggy. What's going on? Why do the lenses always slip after I put them on?

If you find that your vision is blurred after wearing cosmetic contact lenses, it may be caused by infection of the conjunctiva or cornea, resulting in conjunctivitis or keratitis, or it may be caused by damage to the cornea. It is recommended that you go to the hospital for treatment as soon as possible, make a clear diagnosis, treat the cause and symptoms, and pay attention to eye hygiene.

1. Wearing the lenses upside down

2. Too much lens care solution: A small number of wearers bring in too much preservation solution when wearing the lens, which causes the lens to not fit on the cornea and cause the lens to slip. 3. Excessive reflex tear secretion during initial wear by first-time wearers: Some first-time wearers will have increased tear secretion due to lens stimulation in the first few minutes of wearing the lens, which will increase the lens' mobility and cause the lens to slip. You should wait for about 15 minutes before doing an assessment and inspection. 4. The lens base curve does not match the eye. If the lens curvature is too large, it will slip. If the curvature is too small, it will not slip, but the lens will be too tight and close to the eyeball, which will hinder normal metabolism.

If you wear cosmetic contact lenses upside down, you will feel a foreign body sensation because the edges of the upside-down contact lenses are tilted and obviously not completely attached to the surface of the eyeball. You can basically tell whether they are positive or negative by carefully observing the curvature of the edges before wearing them. After all, cosmetic contact lenses are a type of contact lens. No matter how good the quality of the lenses is or how high their oxygen permeability is, they directly block the contact between the cornea and the air, and will hinder the cornea's need for oxygen. If you do not pay attention to personal hygiene when wearing them, it is easy to cause bacterial infection. Wearing contact lenses incorrectly, unhygiene, or not removing them for a long time will cause persistent corneal hypoxia and epithelial erosion. Coupled with bacterial infection, it may cause keratitis or corneal ulcers. The most important issue when wearing contact lenses is to take good personal protection and be cautious.

1. Contact lenses always shift on the surface of the eye, which can easily cause blurred vision;

2. After putting on the contact lens, there will be an obvious foreign body sensation. At this time, you need to consider whether the contact lens is worn upside down. So how to correctly distinguish the front and back of the contact lens? You can first put the lens on your finger and observe its edge from the side. If the edge is turned outward, it means that the contact lens is on the back, otherwise it is on the front. Some contact lenses will naturally restore the curvature of the front after being soaked in medicine.
