Lens-ka ugu khafiifsan uguna fudud 1.74 muraayadaha iftiinka buluuga ah ee yaraynaya
ISTICMAALKA SARE 1.74 muraayadaha muraayadaha indhaha
Qalabka lenska ee ugu hooseeya (1.74 index) ayaa ah sheyga ugu khafiifsan uguna fudud aduunka, waana doorashada ugu fiican ee warqadaha awooda sare leh, ama qof kasta oo raba muraayada ugu khafiifsan codsigooda. Waxay leeyihiin 100% ilaalinta UV waxayna si fiican ula shaqeeyaan qaababka qaab-dhismeedka marka laga reebo rim la'aanta.
Dahaarka AR: Saaxiib ku habboon muraayadaha index-sare
Aragtida iyo muuqaalka ugu wanaagsan, waxa fiican in la yeesho dahaarka muraayad-milicsiga (AR dahadhka) oo lagu mariyo muraayadaha index-sare. Muraayadaha tusmada sare ee dahaarka leh ee AR-gu waxay u gudbiyaan ilaa 99.5 boqolkiiba iftiinka isha si ay u helaan aragti wanaagsan.
Sababtoo ah dahaarka AR wuxuu baabi'iyaa muraayadaha muraayadaha, waxay ka dhigaysaa muraayadaha-index-ka sare inay u muuqdaan kuwo aan la arki karin, si ay kuwa kale u arkaan indhahaaga, ma aha muraayadahaaga.
Nalka buluugga ah
Iftiinka buluuga ah wuxuu u dhexeeyaa hirarka dhererka iyo tamarta laga bilaabo 380 nm (tamarta ugu sareysa ilaa 500 nm (tamarta ugu yar).
Markaa, qiyaastii saddex-meelood meel dhammaan iftiinka muuqda waa iftiin buluug ah
Iftiinka buluugga ah ayaa loo sii kala soocay kuwan (tamar sare ilaa tamar hoose) koox-hoosaadyo:
Iftiinka violet (qiyaastii 380-410 nm)
Iftiin buluug-buluug (qiyaastii 410-455 nm)
Iftiin buluug-turquoise ah (qiyaastii 455-500 nm)
Tamartooda sare awgeed, falaadhaha violet iyo buluug-violet waxay u badan tahay inay waxyeello u geystaan isha. Sababtan awgeed, fallaadhahan (380-455 nm) ayaa sidoo kale loo yaqaan "iftiin buluug ah oo waxyeello leh."
Fallaadhaha iftiinka buluuga ah ee turquoise, dhinaca kale, waxay leeyihiin tamar yar waxayna u muuqdaan inay caawiyaan ilaalinta wareegga hurdo caafimaad leh. Sababtan awgeed, fallaadhahan (455-500 nm) waxaa mararka qaarkood loogu yeeraa "iftiin buluug ah oo faa'iido leh."
Fallaadhaha aan la arki karin ee ultraviolet (UV) waxay ku jiifaan wax yar oo ka baxsan tamarta ugu sareysa (violet) ee dhammaadka iftiinka buluuga ah ee iftiinka UV waxay leeyihiin hirar gaaban iyo tamar ka badan tan tamarta sare ee iftiinka buluuga ah ee muuqda. Shucaaca UV waxaa la caddeeyey inuu waxyeelo u geysto indhaha iyo maqaarka.
Ku diyaari muraayadaha shaandhada buluugga ah ee saxda ah
Sidee bay u caawin karaan muraayadaha yaraynta iftiinka buluuga ah
Muraayadaha yaraynta iftiinka buluuga ah ayaa la abuuray iyadoo la isticmaalayo midab la dhayalsan oo si toos ah loogu daray muraayadda ka hor habka shubista. Taas macnaheedu waa sheyga yaraynta iftiinka buluuga ah waa qayb ka mid ah walxaha muraayadaha oo dhan, ma aha oo kaliya midab ama dahaar. Nidaamkan shatiga leh wuxuu u oggolaanayaa iftiinka buluuga ah inuu yareeyo muraayadaha si loo shaandheeyo qadar sare oo nalka buluuga ah iyo iftiinka UV labadaba.
Qodobbada muhiimka ah ee ku saabsan iftiinka buluuga ah
1. Iftiin buluug ah ayaa meel walba yaal.
2. fallaadhaha iftiinka ee HEV waxay samada ka dhigaan buluug.
3. Ishu aad uguma wacna inay xidho iftiinka buluuga ah.
4. Soo-gaadhista iftiinka buluuga ah waxay kordhin kartaa khatarta ah xumaanshaha macular degeneration.
5. Iftiinka buluuga ahi waxa uu ka qayb qaataa cidhiidhiga indhaha dhijitaalka ah.
6. Ilaalinta iftiinka buluuga ah ayaa laga yaabaa inay ka sii muhiimsan tahay qalliinka indhaha ka dib.
7. Dhammaan nalka buluuga ah ma xuma.
