Smart Phone ki neeli roshni aap ko andha kar sakti hai

Mobile phone aur Laptop ki screen ko tawatar se dekhnay walay khabardaar ho jaien ke un ki benaye mutasir honay ki sharah mein taizi askati hai .

American state Ohio mein waqay Toledo University ke researcher ney apni tahaqeeq mein paaya ke digital alaat se niklny wali neeli roshni ki wajah se aisa keemiyai madah peda honay lagta hai jis se hamari aankhon mein mojood roshni ke liye hassas cells marnay lagtay hain. Is honay walay nuqsaan se macular degeneration ka amal taiz raftaar hojata hai. macular degeneration aisi bemari hai jis ke shikaar shakhs ko manzar ka darmiyani hissa ya to dhundlaa nazar aata hai ya nazar hi nahi aata. Yeh umooman aisay logon ko la-haq hoti hai jin ki umar 50 ya is se ziyada hai aur is marz ka koi ilaaj nahi.

Mohqiqeen ke mutabiq hum neeli roshni se ghiry hue hain aur bad-qismati se hamari aankhon ka cornea aur lens is roshni ko rok ya munakkis nahi karsakta.

Neeli roshni mein ziyada tawanai hoti hai aur is ko tole mouj ya wave-lenght bhi doosri roshni ke muqablay mein chhota hota hai. Yahi wajah hai ke neeli roshni doosri rangon ki roshni ke muqablay mein ziyada nuqsaan da hai.

Mohqiqeen ki team ne logon ko mahswara diya hai ke andheray ya kam roshni mein mobile phone ya laptop ko istemaal nah karen kyun-kay kam roshni ki wajah se aankh ki putli phail jati hai taakay ziyada se ziyada roshni aankh ke parday tak pahonch sakay aur dekhnay mein aasani ho. Lekin is ki wajah se digital alaat se niklny wali neeli roshni mein barri miqdaar mein aankh ke parday tak pahonch kar usay nuqsaan pohanchati hai.

Macular degeneration ka amal photo receptors ki mout se shuru hota hai. Yeh receptors roshni ke liye hassas cells hotay hain jo ke retina ya aankh ke parday mein hotay hain. Un khalion ko retinal nami molecules ki zaroorat hoti hai jo roshni parney par dimagh ko signals bhaijtay hain. Retinal par parney wali neelee roshni ki wajah se photo receptors mar jatay hain. Mohqiqeen ke mutabiq dekhnay ke liye zurori hai ke retinal molecules ki musalsal supply jari rahay. Is ke baghair photo receptors bekar hain.
