My Answers

How do I get new contacts during the coronavirus?
It depends on if your current contact lens prescription is valid (not expired). If it's valid, then can order them through your eye care professional or an online retailer. If your prescription has expired then you may need to get it updated by your eye care professional, which may require a contact lens exam. READ MORE

What can I do to treat my frequent headaches?
There are many causes of headaches. If you are suffering from frequent headaches and they are getting worse each time, then I would recommend you see a neurologist, so that he/she can attempt to rule out emergent causes. In your case, it is very important to determine if the headaches are due to a vision-related problem or not. READ MORE
What is causing eye watering in my son?
Since there are many causes of watery eyes, I would recommend your son visit an eye care professional to determine the cause of his constant watery eyes. The watery eyes could be a sign that the eyes are irritated because they are dry. Although at first this seems counter-intuitive, but if you think about it logically, it makes sense that if sand or dirt were thrown at your eyes, then your eyes would immediately produce defensive tears to protect itself. Treatment for dry eyes is dependent upon the type of dry eye that patient has, so it can be as simple as using artificial tears, but can also involve a more extensive dry eye treatment regimen where the patient is prescribed medication. Watery eyes could also be due to the eye’s poor drainage system where it’s blocked and the eyes become watery. There could also be a foreign body or allergen (allergy -related) that is causing the watery eyes that needs to be removed/treated. READ MORE
Why are my sons eyes always red?

Should I wear sunglasses after Lasik eye surgery?
You should wear your sunglasses at all times when you are either indoors or outdoors for the first 24 hours after LASIK surgery. For the rest of the week, you should wear your sunglasses whenever you go outdoors to protect your eyes from irritants such as dust and wind. Finally, remember to NOT wear your sunglasses whenever you drive at night. READ MORE
Why am I seeing flashes?
Flashes of light in eye may sometimes be caused by the vitreous (the gel that holds the shape of the eye together) pulling/tugging on the retina (the membrane that collects light like a film in a camera), or anything that physically pulls on the retina. I would highly recommend if you are experiencing sudden flashes of light and/or floaters (black spots in your vision) to visit your eye care professional immediately, so that he/she can perform a dilated fundus exam on you to make sure that there are no tears and/or breaks in your retina that can lead to a retinal detachment, which can lead to permanent blindness if not properly treated in time.

How often do I need to clean my contact lenses?
You definitely need to properly clean your contact lenses everyday with a multipurpose cleaning and disinfecting solution to prevent from developing possible eye infections that could lead to loss in vision. You should also remember to clean your contact lenses everyday even if you do not wear them everyday. For example, if you are wearing a daily monthly contacts and you decide to skip wearing for a week, you should still clean your contacts for the week that you skipped wearing the monthly contacts. READ MORE
Is it okay to fall asleep with your contact lenses on?
Yes, sleeping in contact lenses can definitely be dangerous because it could possibly lead to eye infections, which in the worst case scenario can cause permanent vision loss and/or blindness. I would high recommend NOT sleeping in your contacts in the future! READ MORE
Why do I see black spots when I stand up?
As we age, the jelly-like substance (vitreous) inside our eye becomes liquified, which sometimes causes some of the fibers of the vitreous to separate from the light collecting structure called the retina, and clump together to form small shadows that you see as "black spots" in your vision, which are known as "floaters." Most of the time floaters are harmless, but if you start to see many new floaters or flashes of light (like camera flashes), then it's a possible emergency, and it's time to see an eye care professional immediately! READ MORE
Are there drops available to treat dry eyes?
Dry eyes is a chronic condition that needs to be assessed properly to determine the type and severity of dry eye syndrome. Since there are many different brands of dry eye drops on the market, your eye care professional will be the best person to determine the proper dry eye drops. I usually recommend most of my dry eye patients to use 'Systane Complete' five times a day, or more as needed. I then have my dry eye patients return in 1 - 2 months to assess if the specific brand of dry eye drop is working effectively. READ MORE
What is the reason for repeated pink eye?
I would visit an eye care professional to determine the root cause of your daughter's recurrent pink eye but in my experience, recurrent pink eye is due to patient's not washing his/her hands properly before touching his/her eye(s). Also, pink eye is usually caused by a virus so it can be contagious and spread from one eye to the other eye. Also, frequent flu/colds can cause pink eyes also. Remember, if the pink eyes are due to a viral nature, then using antibiotic drops will be of NO use, since antibiotics are used to treat bacterial infections. READ MORE
Can zero power glasses cause any harm to my eyes?
No, if that is your proper/correct spectacle prescription. However, I would recommend visiting your eye care professional to determine the proper spectacle prescription, since some patients have an unbalanced prescription where one eye has no prescription, but the other eye does require one. If this is the case, then the good eye usually takes over and patient sees fine binocular (with both eyes open) but is unaware that the poorly seeing eye requires correction to see better. READ MORE
Are there any natural ways to get rid of a stye?
To relieve most styes, you can use warm compresses 3 to 4 times a day (15-20 minutes each time). You can easily make your own warm compress by placing some raw rice grains into a new clean sock (small round size like a small potato) and then use a microwave to heat it for about one minute. Be careful your warm compress is NOT too hot that when you place it gently on your affected eyelid with the stye. I would recommend performing the warm compresses for about a week or until stye resolves. If your stye doesn't resolve in about 2-3 weeks, the I would recommend visiting an eye care professional to determine the cause. READ MORE
What treatment do you recommend for amblyopic eye?
I would recommend visiting an optometrist specializing in vision therapy to properly assess the severity of your daughter's amblyopic eye, and possible treatment options. READ MORE
Can a two year old have glasses?
Yes, it is possible for a 2 year old to wear prescription glasses depending on his/her refractive nature and other visual factors determined by your eye care professional. READ MORE
How often should I get an eye examination?
Yes, you should have an annual eye examination by an eye care professional every year to determine if you need an updated spectacle prescription, and your ocular health is fine. READ MORE
Can contact lenses cause eye infections?
Yes, contact lenses can cause eye infections if NOT properly wearing them according to the contact lens wearing schedule determined by your eye care professional and the particular contact lens. Remember contact lenses are medical devices that you are wearing on your eyes that can affect the ocular health of your cornea (the ocular structure located in the front part of your eye that focuses the incoming light). For example, not properly cleaning and storing certain types of contact lenses can cause possible eye infections. READ MORE
Can I wear contact lenses beyond the recommended use?
You should NOT wear your contact lenses beyond the recommended wearing schedule. For example, if you are wearing 2 week daily contact lenses, then you should be discarding these contacts every 2 weeks. If you wear these contacts beyond the 2 weeks then you risk for developing possible protein deposits on your contacts that may affect your vision and comfortability even with continual cleaning of the contacts every day. With improper extended wear of your 2 week contacts, you may also be at an increased risk for eye infections. My recommendation is that if you find that you are extending your 2 week contacts to 3 weeks, then I would consider having your eye care professional evaluate and determine if a monthly daily contact lens would be a better option for you. If this is an option, then you would need to purchase fewer contact lenses and be able to wear them a longer period of time. READ MORE
When should I change my contact lenses?
It depends on the wearing schedule of your particular contact lens. You should visit your eye care professional, so that he/she can properly assess which contact lens type and wearing schedule would be be suited for your visual needs. READ MORE
