Make sure you always have adequate lighting when you work or read. Your eyes will be straining all the time if you're trying to see things without sufficient illumination in the room. Over time, this can cause serious damage. Increase your wattage or the number of lighting fixtures in any given room to solve the problem.
Keep your eyes protected from the sun. You should wear quality sunglasses to protect them from UV rays. If your eyes are frequently exposed to UVB rays, your risks for macular degeneration and cataracts increase. Try picking a pair of sunglasses that block between 99 and 100 percent of UVB and UVA rays.
