Autumn: How does it affect our eyes?

The arrival of autumn marks a significant transition in the natural environment, and also has a noticeable impact on the human body. As the leaves change colour and the weather becomes cooler, the human body undergoes a series of physiological adjustments to adapt to the seasonal changes.

These changes not only affect mood and general well-being, but also have specific implications for the visual system. Understanding the effects of autumn on the human body, and in particular on visual health, is crucial to effectively adapt and maintain an optimal state of well-being during this season.

General Physiological Changes during Autumn

During autumn, the human body undergoes a series of physiological adaptations in response to decreasing temperatures and shorter duration of sunlight. These changes include adjustments in sleep patterns, modifications in metabolism and alterations in immune response. The production of certain hormones and neurotransmitters may also be influenced by seasonal variations, which can have an impact on mood and cognitive function.

Ocular Adaptations in Autumn: Effects on Vision

In line with general changes in the body, the visual system also faces particular adjustments during autumn. Decreased sunlight intensity can affect the eye’s ability to adapt to different levels of illumination, which can lead to increased light sensitivity and decreased visual acuity.

Exposure to longer exposure to artificial lighting, due to decreased daylight hours, can also put additional strain on the visual system.

Impact of Humidity and Temperature on Eye Health

Variation in humidity and temperature during autumn can also have a significant effect on eye health. Decreased humidity in the air can lead to dry eyes and increased irritation, especially in individuals susceptible to conditions such as dry eye syndrome. The use of indoor heating systems during autumn can further exacerbate these problems by causing increased tear evaporation and eye discomfort.

Occurrence of certain eye conditions

During autumn, allergic conjunctivitis tends to be one of the most prominent eye conditions. This condition is commonly triggered by the presence of seasonal allergens, such as pollen and dust mites, which can trigger an inflammatory response in the mucous membrane lining the eye. Typical symptoms of allergic conjunctivitis include eye redness, intense itching, excessive tearing and a burning or irritating sensation in the eyes. Exposure to these airborne allergens during autumn can lead to a significant increase in cases of this condition.

In addition, eye infections, such as blepharitis and keratitis, also become more frequent during this season. The combination of higher relative humidity and fluctuating temperatures creates an environment conducive to the growth of bacteria and other pathogenic micro-organisms. Blepharitis, an inflammation of the eyelids caused by bacterial growth, can present with symptoms such as redness, swelling and crusting at the edges of the eyelids. On the other hand, keratitis, an inflammation of the cornea, can manifest with symptoms such as blurred vision, severe eye pain and sensitivity to light. These eye infections can become complicated if not properly treated and require specific medical interventions to resolve.

In addition to these conditions, autumn can also aggravate pre-existing conditions such as glaucoma and macular degeneration. Glaucoma, an eye disease characterised by progressive damage to the optic nerve, can be affected during autumn due to changes in intraocular pressure, which can increase as a result of variations in humidity and temperature.

Strategies to Better Adapt to Autumn Eye Changes

To ensure optimal eye health during autumn, it is essential to consider implementing a comprehensive eye care regimen. Regular use of artificial tears or lubricating eye drops can help counteract the effects of dry eyes. In addition, regular gentle eye washes are recommended to remove potential irritants and allergens that may accumulate on the ocular surface, which can reduce the incidence of allergy-related eye discomfort.

In addition, it is crucial to take a preventative approach to minimise exposure to environmental allergens and pollutants. Keeping windows closed on days with higher concentrations of allergens, such as pollen or fungi, can help reduce the entry of irritants into the indoor environment and thus reduce the risk of an allergic eye reaction. Also, avoiding rubbing the eyes with dirty hands and practising proper personal hygiene, especially after spending time outdoors, can significantly contribute to the prevention of eye infections and hygiene-related conditions.

When it comes to UV eye protection, quality sunglasses that provide full protection against harmful ultraviolet rays are strongly advised. Sunglass lenses with anti-reflective and polarised coatings can be particularly beneficial as they not only block harmful rays, but also reduce exposure to intense glare and reflections, thus reducing eye fatigue and improving visual comfort.

In conclusion, with a combination of preventive measures, proper care and optical protection, it is possible to maintain optimal eye health and prevent the onset of potential eye complications during the transition to autumn. By being aware of seasonal changes and adopting specific strategies to counteract adverse effects, we can ensure that our eyes are well equipped to face the unique challenges that this beautiful season brings.
