According to dr, Randi Montana SpM, a lecturer of Faculty of Public Health (FKM) Universitas Airlangga (UNAIR) also a specialist of RSUD Dr. Soetomo, blue violet light from the gadget is dangerous. It could fasten age-related macular degeneration (AMD). The blue violet light will enter and ruine the retina. It brings risks of AMD and cataract.

Coconut Water for Brain Protecting Layer
Five students of Faculty of Science and Technology (FST) Universitas Airlangga (UNAIR) have succeeded in creating durameter to protect brain and spinal cord made of coconut water. Durameter made is biocompatible so it is safe to use. The five students were Inas Fatimah, Fadila Nashiri, Karina Dwi Saraswai, Andini Isfandiary, and Fathania. The idea to make brain protecting layer was from the cases of brain concussion. In Indonesia, the cases are in the sixth rank with most patients which reaches 0.4 percent of the population. Durameter made by these students of biomedical engineering and supervised by Dr, drg, Prihartini Widiyanti Mkes, was made of bacterial cellulose of Acetobacter xylinum which was fermented with coconut water. Bacterial cellulose is a natural polymer which is biodeggradable (the waste can be decomposed by bio-organism) with high mechanical characteristic.
