Contact lenses are meant to help you see clearly whilst maintaining crisp visual acuity. Should the trigger a sense of awareness of something in the eye; meet your optometrist at your earliest convenience.

What should I do if my Contact Lenses pop out?
Contact lenses are meant to adhere to the surface of your cornea as seamlessly as possible. If they keep fidgeting, they are not meant for you. You might need a proper fitting where eye care professional will take several considerations before he gives a verdict on why your contact lenses have been so uncomfortable.
Contacts fitting includes study of B.C (base curve) and diameter including the water content it holds. The aperture of the lenses should also be taken into consideration because it decides the amount of light that enters the eye.
If it is too tiny, it may cause tunnel vision because it does not allow your pupil to dilate under poor lighting conditions. Talk to your eye doctor if your lenses keep falling out.
What is the Base Curve of Contact Lenses?
It is the measurement of the back of the curvature of the contact lenses. The base curve is used to determine the curve of your cornea. It is measured in mm and it helps doctors determine the size of your contact lenses.
B.C varies from 8.00 to 10.00 mm. The higher the base curve, the flatter the curvature of the cornea. An example of an average base curve is 8.7 mm.
However, it is almost little to no difference between B.C of 8.4 to 8.6. It does not really make a difference if B.C slightly varies.
Too steep B.C mean lenses lead to tighter fit that may cause scarring whereas too loose contact lenses lead to lenses that keep falling, sliding, and shifting at awkward times.
To prevent yourself from an embarrassing situation, always talk to your eye doctor. Your prescription expires every year, and so do your measurements. The lenses that fit you today may not provide the same level of comfort tomorrow.
Poor Tear Chemistry and Contact Lenses
Your tear film is responsible to keep your lenses comfortable. Sometimes when you have dry eyes syndrome, your eyes are unable to make enough tears to let contact lenses float swiftly.
This condition also makes your contact lenses fall out as they are not able to adhere to the cornea. Using rewetting drops and artificial tears help your eyes stay lubricated and contact lenses hydrated.
Last but not the least, do not try to wear the contacts that you just dropped down on the bathroom floor. No, no amount of disinfection will sanitize your lenses enough to make them safe for your eyes.
Icky surfaces or surfaces that are gnarly invite bacteria & germs that may stick to the surface of contact lenses. Wearing such compromised lenses will help the transmission of bacteria from lenses to your cornea.
And it simply means hideous infections that host a number of symptoms from sore eyes to inflammation, itching, redness & even permanent vision loss in extreme cases.
Do you know contact lens cleanliness also plays an important role in ensuring eye comfortability?
