What causes dizziness, eye strain and nausea when diagnosed with dry eyes?

default
Posted on Mon, 18 Jul 2016
Question: My question os for an opthalmologist. I wear a high eyeglass prescription. Right eye -12.50 and left 11.50. Contact lenses right 11.00 and left is 10.00. I haven't worn my contacts since January since I've been diagnosed with dry eye. I have been wearing my eyeglasses since I bought new ones with this prescription in January. I bought htem with an anti-glare coating.
I've seen my eye doctor at a follow up regarding my MGD and dry eye. My TBUT increased from 5 and 7 to 10 in one eye and 12 seconds in the other eye. I have no corneal staining, dry spots, or cornea scratching, but he can see that the tear film is dry. I've been lubricating my eyes with artificial tears and supplementing with omega fish oil. My eyes are still sensitive to contacts and make-up, however, the burning has lessened.
My question is regarding eye strain, dizziness, and sensitivity to lights. I feel like it happened overnight. My eyes constantly feel strained and whenever I go into a mall or business or watch tv or read, I get dizzy and my eyes feel strained. Driving at night is horrible from the headlight glare. Looking at the computer or my phone strains my eyes, but I noticed trouble with my computer and phone back in January when I first bought my eyeglasses with this new prescription. But the nausea and eye strain has started 2 weeks ago in places. The eyeglass lenses are scratched badly and my eye doc saity it is scattering the light coming through and could cause straining in my eyes. Even though they have the anti-glare coating, the scratches are causing the headlight to glare and all the other lights to be hard on my eyes. Do you agree with this? Basically, can heavily scratched eye glasses cause eye strain, nausea, sensitivity to lights? My TV looks so bright no all of a sudden. I bought new lenses so I am currently waiting for them to arrive this week.
Also, do you think my eyeglass prescription could be too high in regards to my contact prescription? Curious to hear your opinion. Thank you!

Brief Answer:
Scratches can cause strain.

Detailed Answer:
My dear,
Thanks for sending your query to us.
I personally feel these problems are caused by scratches on the glass. You do not see well and so it causes strain. Light is scattered so night driving force is a mess.
The issue will be settled once you get your new contact lenses. Almost all your problems will be gone,that will be a case for having a new glass
.
You can have a anti glare coating or a transparent hard coating. Now i will suggest you to have a hard
coating, which is more scratch resistant.

Use dry eye treatment and contact lenses, once your problem is over (at best in a week), then go ahead with a new pair of glasses.

Higher the power, more is the difference between powers of glasses and contact lenses. Do get back to me in case of any further query in this regard.

Does the scratches mess up the anti-glare coating? Also, what is your opinion on restasis for dry eye? I hear a lot of mixed reviews. Thank you

Detailed Answer:
My dear,
Good of you to get back to me.
The strain and visual phenomenon you mentioned can be related to scratched lenses,but such respinsss by patients are very varied.That may be the reason wby you are havi g cknfusing reports.Again higher the power, more is the disturbance.
Anti glare coating in majority of my patients last no more than 6 months.So we prefer what is known as hard or scratch proof coating.In yojr caserole of sctatches is decided when you use contact lens. If the problems still persist then change in power or any general weaknesses come lower down in our priority list as reasons for your discomfort.
Any further issues,do get back to me for clarification.
