| Lightwave Logic Announces Current Thermal Aging Results Exceed Commercial Requirements             Demonstrates Operational Feasibility at Temperatures as High as 110C with Minimal Degradation Thermal Aging to Company Continues to Push Thermal Step Stress Reliability Studies to Higher Temperatures
 Waveguide Modulator Prototype Development Advances Toward Completion
 
 
 LONGMONT, Colo.,  March 31, 2015 /PRNewswire/ -- Lightwave Logic, Inc. (OTCQB:LWLG), a  technology company focused on the development of Next Generation Photonic Devices and Non-Linear Optical Polymer Materials Systems  for applications in high speed fiber-optic data communications and  optical computing, announced today that it has dramatically advanced the  commercial feasibility of its organic electro-optical photonic device  program.
 
 These results at 110C surpass  the published results of any known electro-optical polymer at that  temperature, but more importantly, they exceed the harsh demands of the  commercial operating datacom/telecom environment that requires photonic  devices to operate consistently at 85C. The ability to operate at  temperatures above 85C opens up an array of additional applications that  at least one of the Company's potential partners for joint development  opportunities has identified during discussions.
 
 While the Company continues to  demonstrate minimal degradation over successive levels of industry  benchmark parameters (See chart below), it is simultaneously moving  toward completion of its operating organic polymer-enabled waveguide  modulator prototype using its new multi-chromophore material systems.

 Tom Zelibor, Chairman and Chief  Executive Officer of Lightwave Logic stated, "The combination of  durability and high electro-optic characteristics of our materials  should lead to commercially competitive devices that will offer enormous  performance improvements at reduced cost.  This will be a win-win for  both Lightwave shareholders and our potential customers.
 
 "The ultimate goal is to  increase thermal stress on our materials at even greater temperatures to  prove our utility beyond datacom and telecom and into markets such as  high-speed computing that have require even greater temperature  requirements.
 
 "We increased R&D  expenditures in 2014 by 38% and we will continue to increase our R&D  commitment in 2015 in an effort to accelerate completion of additional  demonstration waveguide devices. We anticipate having reportable device  data by the Annual Shareholder Meeting in May.
 
 "We are experiencing increased  industry interest in our progress as there exists strong pent up demand  for a cost-effective way to reach data rates of greater than 100Gb/s  with miniaturized photonic devices that consume less power.  We are now  one step closer to fulfilling this need."
