more Common Eye Problems
Night blindness describes a condition where you can not see anything in the dark. This is different than just having difficulty seeing at night. The most common cause of night blindness is a group of diseases called retinitis pigmentosa. Retinitis pigmentosa is a genetic disease that will cause someone to slowly lose their vision over time. Night blindness is typically the first symptom that is noticed. Night blindness can also be caused by a deficiency of vitamin A.
If you are noticing troubles seeing at night, come visit us for an assessment! Difficulty at night can be caused by having an uncorrected prescription, cataracts or general problems with glare.
Cone cells are what let your eyes see color. If yours are either missing or just not working, you will not be able to see certain colors, making it hard to tell them apart.
The most common colors that cannot be distinguished are reds and greens. In severe cases, you can only see shades of grey.
Usually color blindness is a genetic condition and is present at birth. Color blindness can affect how a child learns and therefore it is important to get your kids checked early so that their learning is not affected! Sometimes, color blindness can be acquired later, which can signify a serious condition and should be checked immediately by an eye professional.
Fun fact: Men are more likely to experience color blindness.
Do you see tiny specks that "float" around and across your field of vision? While you may think they're floating in front of your eye, they are actually inside! They are usually clumps of protein or cells naturally present in your eye that cast a shadow onto your retina. These shadows are more noticeable looking at a white wall or on a bright day looking at the sky. Do not panic! It is very normal to experience floaters with age, however noticing a sudden increase in floaters could be an eye emergency.
Other symptoms of an eye emergency is seeing flashing lights or lightning streaks! These are called flashes. Furthermore, seeing a shadow in your side vision, or a dark curtain/veil in your vision is also an emergency. A new occurrence of either flashes, floaters or a shadow or curtain/veil over your vision is an emergency and you should come see us right away! These are possible symptoms of a retinal detachment, a condition in which the sensory part of your eye detaches from its blood supply. This can result in death of the retina and permanent blindness if this is not treated right away.
Problems with Contact Lenses
Contact lenses are a great alternative to glasses and millions of people are able to wear contact lenses without any problems. However, there is a risk of having an eye infection from wearing contacts!
Some causes for infection include:
- sleeping in your contacts
- not cleaning your lenses with the appropriate solution (tap water should NOT be used to clean the lenses or the case!)
- showering or swimming with contacts (any contact with water, whether it be treated or not, should be avoided!). Any time contact lenses contact any water, they should be thrown away as soon as possible! Therefore, the best type of lenses for swimming are daily disposable lenses.
- reusing or topping off contact lens solution
- using a dirty contact lens case (cases should be replaced every 3 months)
Severe eye infections from contact lenses can cause serious vision loss and even blindness. If you notice any of the following symptoms: redness of the eye, eye pain, tearing or discharge from the eye, light sensitivity or changes in your vision, it is important to come see us as soon as possible.
