Dry eye is a multifactorial disease of the tears and ocular surface caused by decreased aqueous secretion or excessive evaporation.
Most experts agree that dry eye can be divided into four levels.
Grade 1 and 2 dry eye syndrome can be improved using lubricant drops, applying daily eye washes, using solutions containing phospholipids, etc. Patients with grade 3 and 4 dry eye will need to see an ophthalmologist.
Grade 1 dry eye disease (normal - mild)
This group generally includes people who are exposed to adverse environmental conditions, who spend a long time working with computers, etc.
It is advisable to use moisturizing drops to restore tear balance, and to take eye baths in order to clean and hydrate the surface of the eye.
Grade 2 dry eye disease (mild - moderate)
This applies to people with a more sustained problem who require specific preservative-free treatment. It can affect either the lipid layer (hyperevaporative dry eye disease) or the aqueous layer, or both, with each case requiring specific treatment.
