Scleral lenses & Hot Weather Habits: Preventing Drying and Deposits in Summer

Summer has a way of turning even the most composed routines slightly… unruly. Ice melts too quickly, mornings feel louder, and somewhere between the sunlit pavement and the second iced coffee, your scleral lenses begin to remind you that they, too, are subject to the season’s temperament.

At OC Optometry Group, we often remind patients that scleral lenses are marvels of modern vision science—tiny liquid vaults designed to bathe the cornea in comfort. But even marvels require mindfulness, especially when temperatures rise and evaporation accelerates.

The subtle science of summer dryness

Scleral lenses rely on a reservoir of saline fluid to maintain optical clarity and ocular hydration. In hot, dry environments—whether coastal heatwaves in Newport Beach or air-conditioned interiors that mimic desert winds—this reservoir can evaporate more quickly than expected. The result? Midday fogging, fluctuating vision, and a sensation that your lenses are quietly negotiating their departure from comfort.

The solution is not dramatic; it is deliberate.

Hydration begins before the lens

Think of your lenses as guests at a long summer dinner party. They arrive best when the environment is already prepared. Using preservative-free saline that is specifically recommended for scleral lens filling ensures stability. Avoid topping off with tap water or reusing leftover solution—tempting shortcuts that lead to osmotic chaos and, more importantly, irritation.

And yes, your own hydration matters too. A well-hydrated body supports tear film quality, which in turn supports lens stability. In summer, water is less of a suggestion and more of an accessory.

Combatting deposits: the invisible summer souvenir

Heat does not only evaporate moisture—it also accelerates protein and lipid deposition. Sunscreen, sweat, and airborne particulates seem to conspire artistically on lens surfaces, leaving behind subtle smudges that compromise clarity.

A disciplined cleaning routine becomes essential. Daily surfactant cleaning followed by a rigorous hydrogen peroxide system (when appropriate for your lens type) helps maintain optical purity. Rub, rinse, and respect the process—because in scleral lens care, elegance is repetition.

Environmental finesse: air, wind, and discretion

Air conditioning can be both savior and saboteur. While it keeps you comfortable, it also lowers humidity, increasing lens evaporation rates. Consider using a humidifier in frequently occupied indoor spaces. Outdoors, sunglasses act not just as style statements but as microclimate shields, reducing tear evaporation from wind exposure.

And if you find yourself at the beach—because summer does insist—remember that sand and lenses are not friends. They are, at best, brief acquaintances with very different expectations.

The midday refresh ritual

For extended wearers, a midday lens refresh can be transformative. Removing, rinsing, and refilling lenses with fresh saline restores optical clarity and comfort. Think of it as a reset button for both vision and temperament.

Scleral lenses are engineered for endurance, but summer asks for partnership. When cared for with intention, they respond not just with clarity, but with remarkable consistency—even under the most radiant skies.
