If your usage in front of digital screens of Desktop, Laptop, Smartphone, TV etc is less than 2 hours a day or if you still work with pen & paper and not by using any means of electronic devices, then it is not much required to read this blog post. In such a case you may even choose not to buy the computer glasses or in better words it is completely optional for you to wear the protective glasses.
In current scenario of ophthalmic industry, mainly there are two type of lenses for computer users:
Clear Lenses – These are non colored protective lenses that block the harmful blue light of the computer rays. Electromagnetic interference (EMI) and Scratch resistance and Hydrophobic are the key qualities of this lens type.
Amber Lenses – They are colored lenses and are impact resistant. Amber lenses are dipped in a unique anti blue light chemical that makes them foremost choice of IT professionals. The best thing about this lens type is that they have been specially engineered for heavy computer usage.
Who is not ? May be the question should be that who is not an IT professional in today’s world ? Any person who has taken special education or is technically skilled or is employed to perform tasks on computer can be termed as an IT professional. Information Technology (IT) professional is a broader term and does not necessarily mean a software programmer who writes thousands of codes in programming languages like C#, JAVA, PHP, Python etc. Even a blogger who expresses his knowledge on a web page or a YouTuber who shoots videos by his DSLR/ Smartphone camera and does video editing or or a BPO/MNC employee who spends hours in front of digital screens also qualifies the criteria of an IT professional. Apparently most of the people and especially the youth that uses information technology in the professional life fall in the aforesaid segment.
