There are two kinds of people: one, who love their power glasses for their style statement, and others who thoroughly hate them for they come with an awful lot of precautions, are slippery and can break easily.
Taking them on treks might mean that you end up saving them instead of them saving you! So, what is the alternative?—Contact lenses?—but they too have their set of pros and cons.
Today we thought of giving this problem thought and bringing out our collective wisdom and experience of trekking with eyesight.
So, what should you wear—Contact Lenses or Glasses on treks?
— Glasses are easy to wear.
— These are cheaper than contact lenses.
— Offer better protection against wind, dirt and grime.
— These are low-maintenance. You just have to clean them from time to time and keep them in a box for safety.

— They can easily break. While jumping on rocks and crossing streams, you might lose your glasses. You also don't want to compromise your vision while hiking or taking a shower in a waterfall, etc. The sad truth is that you cannot in any way carry these to some places.
— Fog is a big problem with glasses. I have observed that steam fogs up my glasses when there is a sudden change of weather. And mountains are notorious for changing weather. Especially during or after the rain, you have to be careful.
— They are the worst in the rain. While the droplets sit restlessly on the glasses, the refractive index is shifted. This again compromises vision.
— They slip and grease easily in the rain or sweaty conditions. You will not be able to wear them since they will keep coming off.
— They correct your vision without changing your appearance.
— They offer better vision.
— Fog does not accumulate on contact lenses.
— Once worn, they will last for upto 10 hours.
— Wearing lenses with sunglasses is like wearing sunglasses on a normal eye.
— Putting them on is a pain in itself. For beginners, wearing contact lenses is a task. We have experienced teary eyes, lens falling off ten times and lens getting dirty because of this. Then, the setup is of the mirror, lens solution is required on the side. Hence, practice wearing them and get acquainted with them.
— You can quickly lose them - they may tear off, fall off, get lost.
— Contact lenses can only be worn for upto 8 to 10 hours. This allows the eyes to breathe and rest.
According to Mayoclinic: “Bacteria, fungi or parasites — particularly the microscopic parasite acanthamoeba — may inhabit the surface of a contact lens or contact lens carrying case. The cornea may become contaminated when the lens is in your eye, resulting in infectious keratitis. Over-wearing your contact lenses can cause keratitis, which can become infectious.”
— Dry Eye Syndrome. This occurs when your eye is not able to produce tears/fluid properly. Cheaper lenses may cut the whole oxygen supply to the eye. Dry eye syndrome occurs with more than half of the population that wears contact lenses.
— On high altitudes, with improper hygiene, you might get eye infections like conjunctivitis. Contact lenses do not provide the same protection as glasses. Your eyes are much more exposed to dirt and other microbes because of which chances of infections increase.
— The solution tends to freeze in colder seasons. Trekkers can keep the solution in their sleeping blankets or in pockets to keep it from freezing. It will remain in the liquid because of body heat.
— They might come out if you wash your face due to rubbing etc. And the worst part is, you will not even know until you see the atmosphere nearby. When things become hazy, your brain will signal that something worse has occurred
Final Word: This tug of war between contact lenses or glasses on treks will stay alive. But one rule of thumb is to prefer glasses if your power is upto -2.00. Even if the lenses break, you will conveniently do the trek. Others should choose contact lenses because they will not break. Even during a harsh climate, you will not have to keep shifting them from here to there.
