00:00When the rays of the sun fall directly on the eyes, it affects the eyes, this disease is called Snow Blindness.
00:09What is Snow Blindness? Which people are more affected by this disease?
00:14And what precautions should be taken during the days of snow blindness?
00:18We have with us the famous ophthalmologist of the valley of Kashmir, Dr. Asif Ameen Makhil, who is an associate professor at GMC Srinagar.
00:28Welcome Dr. Makhil.
00:30Thank you very much.
00:31First of all, I would like to know what Snow Blindness really is?
00:34Because the general public does not know that Snow Blindness is also a disease that affects the eyes.
00:41Yes, this Snow Blindness, what happens in this is that in winter, the geographical region in which we live, this is above the sea level,
00:53here the ozone level is already low, so the UV light is more.
00:59There are three types of UVA, UVB and UVC.
01:03Usually, UVC, the atmosphere itself stops it.
01:08It is a natural disease, due to the ozone layer, due to the atmosphere, it cannot reach here.
01:1690% of UVB also gets cut due to the atmosphere.
01:20Only 10% of UVB reaches the earth.
01:24So most of the UVA reaches the reddish.
01:28So this thing, the more we go above the sea level, the more it increases.
01:34Because the cutting effect of the atmosphere decreases, it can reach us more.
01:42When we talk about Snow Blindness, it is a particular term.
01:47Rebound, one is coming from above, the other is also affecting us with rebound.
01:53Like a white sheet of paper.
01:55So normally when there is no snow, the earth absorbs it.
02:00When there is snow, it radiates and affects us again.
02:05So why is it called Snow Blindness?
02:08Because what happens with this, when UV light falls on our cornea,
02:12which is transparent in front of our eyes.
02:16In this, there is a slight wound due to the UV light.
02:20If someone gets acutely, then there is a slight wound.
02:24So after 8 hours, the patient understands the result of it.
02:29What happens in that?
02:31Symptoms.
02:32Tears start coming.
02:34It turns red.
02:35It feels like a chili has fallen in the eye.
02:38So this is because of the damage to the cornea.
02:44It is called photokeratitis in some medical terms.
02:47So in common language, it is called Snow Blindness.
02:50Does it also cause pain in the eye?
02:52Pain, definitely.
02:53So it becomes difficult to open the eyes.
02:56This is why it is called Snow Blindness.
02:58Can this affect everyone who leaves the house during snowfall?
03:03Or the players who go to Gulmarg or other places?
03:06Very good question.
03:08It is very apt for this time.
03:10Because we are welcoming all these scares right now.
03:13The more exposure there is,
03:16so it depends on how much exposure there is.
03:20Like in Gulmarg and Silmarg,
03:22the higher we go, the more UV light will fall.
03:27The scares that are coming,
03:30they can be affected more than this.
03:33So they should be very careful.
03:37This is a very good step that we are educating people.
03:42UV protected sunglasses is a must.
03:46It should be 100% UV blocking.
03:49Actually, a lot of people,
03:52except for professional skiers,
03:54they wear any type of sunglasses.
03:57That is more dangerous.
04:00Because of the darkness, the pupils dilate more.
04:04And the sunglasses that are sold in the market,
04:10because of that, the radiation cannot be cut.
04:13Because they are only dark.
04:15They don't give you UV protection.
04:17So basically, we need UV protection.
04:21Please take those sunglasses for skiing.
04:25Which are 100% UV blocking sunglasses.
04:30Not any ordinary dark glasses.
04:33Because of this, we have seen a lot of patients
04:36who come with these symptoms.
04:38If someone is living there for a long time,
04:41working there for months,
04:44it is more important for them.
04:46Because when this exposure is happening every day,
04:49even if they are not getting photokeratitis,
04:52there is a risk of getting different diseases,
04:55long-term diseases.
04:57If you look at simple diseases,
05:00it can be conjunctivitis,
05:03it can be bengalitis,
05:05it can be lid tumors,
05:07it can be intraocular tumors,
05:09but in those,
05:11it can be due to UV light.
05:15As an ophthalmologist,
05:18I would always suggest
05:20to wear UV protected sunglasses.
05:23Especially in this geographical zone.
05:26This means that it should be worn by ordinary people as well as skiers.
05:29Not only for the winters,
05:31it should also be worn in the summers.
05:33Because we have seen that
05:35in this geographical area,
05:37all the diseases that occur due to UV light,
05:40are more common.
05:42For example, there is spring catar in Bachu.
05:45There is a lot of involvement from April onwards.
05:49Because we are not sensitized
05:53for wearing UV protected sunglasses
05:56as a measure of protecting our eyes.
05:59Sunglasses are considered to be cosmetic.
06:02But actually, it has a very functional role.
06:05To prevent age-related macular degeneration,
06:09UV blocking glasses play a very important role.
06:13Doctor, I would like to know,
06:15the eyes are affected.
06:17Is there a risk of blindness in this disease?
06:20Specifically, we are talking about snow blindness.
06:25Can it only affect the eyes?
06:27Yes, it can affect the eyes.
06:29There are irritable symptoms in the eyes.
06:34In a short exposure,
06:37which is called snow blindness.
06:39But as I said,
06:41if it is a long-term exposure,
06:43then other dangerous things can also occur due to UV light.
06:47Is there any age group that is affected by this?
06:51No.
06:52There is no age group in which there will be exposure.
06:55Snow blindness is due to acute exposure.
06:58It can happen to anyone.
07:00As you see 4PD every day,
07:02what kind of patients do you have
07:04who come to you during the monsoon?
07:06In the monsoon,
07:08we bring dry ice.
07:12As you know,
07:14we like to sit in front of heating gadgets.
07:18Whether it is a gas heater,
07:20blower, air conditioner,
07:22it gives dry heat.
07:24So, there is dehumidification in the room.
07:27Because of that,
07:28there are dry eye symptoms,
07:29irritation in the eyes.
07:31Many patients come for this.
07:33Okay, let's talk about the treatment.
07:35What kind of treatment is available for this
07:38if someone is affected by snow blindness?
07:40Look, we don't have to worry about snow blindness.
07:44So, what we do is,
07:46we give lubricating drops
07:48depending on the amount of wound.
07:51If it is too much,
07:52we may patch overnight.
07:54But mostly,
07:55we give lubricating drops
07:57to the patients.
07:59And ice packs.
08:00The treatment is the same.
08:02Ice packs
08:03and lubricating
08:05gives relief to the patient.
08:08Basically, the aim is to give relief to the patient.
08:11As an eye specialist,
08:13do you have any message
08:15for the people who want to consult you?
08:17My message is
08:19to come for skin care.
08:21But take care
08:23of your skin care.
08:25Ice is very vital
08:27because it is a very sensitive organ.
08:30If you expose it directly,
08:32the UV radiation is very high.
08:35I don't think people are sensitized
08:37or educated about it.
08:39The higher we go from the sea level,
08:41the more UV light
08:43can affect you.
08:45So,
08:47you should invest
08:49in good UV blocking sunglasses.
08:52Especially those
08:54which have gaps.
08:56For example, glasses have gaps.
08:58You must have seen professional skiers.
09:01Their sunglasses
09:03are closed from the sides.
09:05And they are
09:07glued to the skin.
09:09That is
09:11because
09:13if you wear glasses,
09:15they reflect light from below
09:17and go into the eyes.
09:19So, those sunglasses
09:21which are snugly fit,
09:23especially those for skin,
09:25are very important for them.
09:27Snugly fit UV blocking sunglasses.
09:31Dr. Asif Amin,
09:33thank you very much
09:35for your time.
