A: Do not wear contact lenses overnight (except day and night type).Because, contact lenses in the eye for too long, will cause the lack of cornea caused by corneal edema, resulting in a decline in corneal resistance.
In addition, the secretion produced by the eyes is deposited on the lens and cannot be removed in time. The sediment adheres to the surface of the lens and makes the surface of the lens rough. In this way, it will produce great stimulation to the cornea and conjunctiva, leading to the occurrence of eye complications.
In addition, the lens accumulations of a certain thickness of sediment, will appear the vision is not clear, wear time and lens life will be shortened.Therefore, wear contact lenses should be picked every day, and undertake cleaning, disinfection, wear every day, wash every day, the most healthy.

What is lens sediment?Where did it come from?
A: There are a lot of protein components in the tears in our eyes, and the eye glands also secrete a lot of lipids. In addition, contact lenses are exposed to the air and come in contact with many foreign bodies, dust and microorganisms, which are the sources of precipitation. The materials of lenses are hydrophilic, so adsorption and precipitation are inevitable.
Generally speaking, there is sediment formed one minute after wearing the lens, 50% of the lens area is covered by sediment after 30 minutes, and 80% of the lens area is covered by sediment after 8 hours.
Where is the harm of lens precipitate?
Answer: can cause irritation reaction, make the wearer's comfort drop, the accumulation of sediment will also reduce oxygen permeability, cause hypoxia;Sediment also blocks light from entering, causing blurred vision;The sediment will also adsorb microorganisms and cause secondary infection.More serious is caused by the eyelid conjunctiva immune response, leading to megapillary conjunctivitis.
What happened to the broken lens?
A: Soft lenses are more delicate, repeatedly rubbing, picking, wearing and pinching for a long time, affected by radiation in the environment, and aging of materials are easy to produce edge defect, central crack, small hole damage and other conditions. In serious cases, corneal scraping, oxygen permeability disorder and visual deformation will occur, affecting normal wearing.
