The tools for accessing the information (smartphones, tablets) in the hands of children have increasingly been causing visual acuity conditions. The same is also true for adults, but they have been relying on electronic visual aids to carry on with their daily lives. Such findings indicate that children's eye care needs more attention, especially also for children with low vision. When Are Low Vision Aids Necessary? A low vision condition is when a person has visual impairment on the scale of moderate to severe which also inhibits their daily activities.

More than a million residents in the US are diagnosed with Dry Eye Disease, and over 15% of the world population suffers from it. But these are only confirmed estimates, so it's unnatural to get a grasp on the actual number. However, an optometry specialist adds a revelation to the ongoing studies about dry eye care: tear evaporation likely plays a key role in DED! What is Tear Evaporation? In simple terms, tear evaporation is the process where the aqueous substance of the tears evaporates from the eye surface. The tear layer is composed of the lipid (oily) layer, the aqueous (water) layer, and the mucin layer. In a general scenario, the lipid layer prevents excessive drying or evaporation of tears so the eye can maintain proper lubrication. However, the current environmental factors also play a role in degenerating eye health. For instance, the differences in the humidity levels in the environment and seasonal changes can increase the tear evaporation, thereby decreasing the tear
