Osmolarity means density. The density should be at the normal level, not too little or too little.
With the decrease in mucin size, filamentous filamentous structures are formed. The increase in density and decrease in tears causes damage to the corneal epithelium and its susceptibility to infection.
The osmilarity of tears is around 303-305 mosm/L. After 316, it is evaluated as an excess of density.
Intensity should be at normal level.
A decrease in the water (aqueous) size of the tear increases the osmolarity. That is, the tears become heavy, sludge, become sticky, vision deteriorates, toxic elements and residues are not thrown out of the eye.
why does the ember decrease?
*Reduced blinking reduces aqueous. The reason for this is to look at the computer and mobile phone for a long time, to read for a long time. Blinks, which are around 28-30 per minute, decrease to 7-8. Remember, when you blink, tears are released.
*Hot environments, air conditioning, and summer months cause aqueous loss.
*Contact lens is the most important cause of dry eye, it increases tear density. As the water content in the contact lens increases, it absorbs the water of the eye like a sponge. Lenses with a low water content should be used.
*Dozens of systemic diseases reduce aqueous production.
Rheumatic diseases (rheumatoid arthritis and others) Diseases such as sjogren’s syndrome diabetes thyroid disease, systemic lupus and polymyositis reduce aqueous production.
*The diet that causes fluid loss from the body reduces aqueous. Caffeine, alcohol, a lot of tea, cigarettes, cola and carbonated drinks, chips, etc.
*Aqueous loss: It is necessary to keep the aqueous for a reasonable period of time. If the mouth of the meibomian gland is clogged with oil residue, the oil will not meet with the aqueous, it will run off, or it will evaporate and fly away quickly.
Are you aware, we are always talking about density increase due to aqueous reduction. The decrease in density, that is, the abundance of tears, is a matter of speech in the obstruction of the lacrimal sac, but the tears leave the eye by flowing out of the lids, not from the duct.
If the tear does not leave the eye, infection develops. You can think of it as stagnant water getting dirty and it’s a waste to the eyes again.
