• what kind of glasses can reduce eye strain when working on the computer ?

  Computer glasses are special glasses prescribed to lessen the symptoms associated with computer vision syndrome (CVS). CVS describes a group of symptoms caused by prolonged computer use. Symptoms appear because the eyes and brain react differently to words on a computer screen than they do to printed text. Symptoms often include eyestrain, dry eyes, headaches and blurred vision. Many people try to compensate for these vision problems by leaning forward or by looking down to see through the bottom portion of their glasses, often resulting in back and shoulder pain.

• Will it make a big differentce when wearing glass glasses or plastic glasses?

  Glasses optical clarity is the best and as such glass lenses will have little to no distortion.Adding to that, it is the most scratch resistant optical material.However, glass will almost certainly shatter on impact. Plastic lenses are mainly made from polycarbonate and CR-39 plastic material. Polycarbonate is popular for lenses because of its high resistance to impact. polycarbonate lenses also have the highest distortion compared to any other material. CR-9 is another type of optical plastic. It has little distortion compared to polycarbonate. It is thinner and lighter than glass too.plastic being a lighter material makes plastic lenses much lighter than glass and therefore they are less likely to cause indentations.
