Visual perception refers to the ability to interpret and make sense of visual information from the environmentthrough the process of sight.

Visualperception is the ability to interpret the surrounding environmentthroughphotopic vision (daytime vision), colorvision, scotopic vision (night vision),and mesopic vision (twilight vision),using light in the visible spectrumreflectedby objectsinthe environment.

This complex process involves severalsteps, beginning with the detection oflight by the eyes and ending with theinterpretation of visual stimuli by thebrain.

Visualperceptionallowsindividuals to understand and interactwiththeir surroundingsby recognizing,organizing,andinterpreting shapes, colors, spatial relationships, movement, and othervisual attributes.This is different fromvisual acuity, which refers to howclearly a person sees (for example"20/20 vision"). A person can haveproblemswith visualperceptual processing even if they have 20/20vision.

Acute eye conditions are vision-threatening conditions thatrequire attention by an eye care professional within the firsttwenty-four (24) hours. Patients who notice a red eye or other
acute ophthalmic symptoms often present first to their generalpractitioner, optometrist, or local hospital emergencydepartment.

While the most common acute eye diseases in primary practice are usually benign conditions of viral,bacterial, and allergic conjunctivitis, rarer but more seriouscauses of the red eye such as iritis, keratitis, and acute
glaucoma can lead to permanent loss of vision.

The primaryhealth care provider’s initial diagnosis and management canbe critical to the patient’s ophthalmic outcome.

The connection between what we eat and how well we see ispretty complex. It's not just about getting the right vitaminsand minerals; it also involves our eating habits, how much money we have, and even how we think about food.

Nutritional intake plays a significant role in maintaining eyehealth and preventing age-related eye diseases. Natural foods such as fish, meat, eggs, nuts, legumes, citrus fruits, leafygreen vegetables, and orange-colored fruits and vegetables are essential for boosting eye health.

Additionally, the consumption of foods rich in ω-3 fatty acids, lutein, and zeaxanthin, such as flax seed oil and marigold powder, hasbeen associated with promoting eye health and reducing therisk of Age-related eye diseases.

Furthermore, dietary patterns and carbohydrate intake have been linked to age-related eye diseases, including macular degeneration, diabeticretinopathy, and cataracts. It is evident that a diet rich in antioxidants, anti-inflammatory agents, and neuroprotective
nutrients is beneficial for ocular health.

Common ocular measurement plays a crucial role in the field of optometry, helping eye care professionals assess and diagnose various visual conditions.

These measurements provide valuable insight into the structure and function of the eye, aiding in the prescription of corrective lenses, monitoring eye health, and detecting potential abnormalities.

Here are some of the common ocular measurement:
Visual acuity:

Visual acuity is a measure of the clarity of vision, typically assessed using an eye chart. The Snellen chart is commonly used, and results are expressed as a fraction (e.g., 20/20). A person with 20/20 vision can see at 20 feet what a person with normal vision can see at 20 feet.

Refractive error

Refractive error measurements determine the need for corrective lenses. Common refractive errors include myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. The prescription is usually expressed in diopters(D).

Pupillary distance

PD is the distance between the centers of the pupils. It is essential for accurately fitting eyeglasses, ensuring that the optical centers of the lenses align with the patient's pupils.

Intraocular pressure

Intraocular pressure is the pressure within the eye. Elevated IOP is a risk factor for glaucoma, a condition that can lead to optic nerve damage and vision loss. Tonometry is the common method used to measure IOP.

Corneal topography

Corneal topography maps the curvature of the cornea, providing detailed information about its shape. This is crucial for planning refractive surgeries like LASIK and for diagnosing conditions such as keratoconus.

Keratometry

Keratometry measures the curvature of the cornea's front surface, typically focusing on the central portion. This is important for determining the power of contact lenses and assessing corneal astigmatism.

Visual field testing

Visual field testing assesses the full horizontal and vertical range of vision. It is crucial for detecting conditions like glaucoma, which often cause peripheral vision loss.

Axial length

Axial length measures the distance from the front to the back of the eye. It is particularly important in pre-operative evaluations for cataract surgery and refractive surgery.

Slit lamp examination

Slit lamp examination allows for a detailed view of the eye's anterior segment, including the cornea, iris, and lens. It is essential for detecting conditions such as cataracts, corneal abnormalities, and uveitis.

Retinal imaging

Various imaging techniques, including fundus photography and optical coherence tomography (OCT), provide detailed images of the retina. These are crucial for diagnosing and monitoring conditions such as macular degeneration, diabetic retinopathy, and retinal detachments.

Accurate and comprehensive ocular measurements enable eye care professionals to provide personalized and effective care, ensuring optimal vision and early detection of potential eye diseases. Regular eye examinations are essential for maintaining overall eye health and preventing vision-related issues.

*Nourishing Your Vision with a Healthy Diet*

Maintaining good eye health is crucial for our overall well-being. While regular eye check-ups and proper eye care are essential, incorporating a healthy diet can also play a significant role in promoting optimal vision. Certain foods are rich in nutrients that support eye health and can help prevent age-related vision problems.

Here are some key foods to include in your diet for healthier eyes.

*Citrus Fruits and Berries*

Citrus fruits like oranges, lemons, and grapefruits are rich in vitamin C, which is an antioxidant that supports eye health. Berries, such as blueberries and strawberries, are also great sources of antioxidants and help protect the eyes from damage caused by oxidative stress, reducing the risk of cataracts and macular degeneration.

*Carrots and Sweet Potatoes*

Carrots and sweet potatoes are rich in beta-carotene, a precursor to vitamin A, which is essential for good vision. Vitamin A helps prevent night blindness and supports the overall health of the eyes. Including these orange-colored vegetables in your diet can contribute to maintaining healthy eyesight.

*Leafy Green Vegetables*

Leafy green vegetables such as spinach and collard greens are packed with nutrients like lutein and zeaxanthin, which are essential for maintaining healthy vision.
These antioxidants help protect the eyes from harmful ultraviolet (UV) rays and reduce the risk of macular degeneration and cataracts.

*Fish and Omega-3 Fatty Acid*

Fatty fish like salmon, tuna, and mackerel are excellent sources of omega-3 fatty acids, which are known to promote eye health. Omega-3 fatty acids help prevent dry eyes and reduce the risk of age-related macular degeneration. If you're not a fan of fish, you can opt for flaxseed, chia seeds, or walnuts as alternative sources.

*Nuts and Seeds*

Nuts and seeds, such as almonds, sunflower seeds, and peanuts, contain vitamin E, which is beneficial for eye health. Vitamin E helps protect the eyes from free radicals and reduces the risk of age-related macular degeneration. Snacking on a handful of nuts and seeds can be a nutritious way to support your vision.

Incorporating these eye-healthy foods into your diet can provide essential nutrients that promote good vision and reduce the risk of eye-related problems.

EYE COSMETICS AND ATTRIBUTABLE RISKS

An eye cosmetic is anything put on/in the eye to enhances it and make the eye look noticeable and attractive. Eye cosmetics available today include; eye pencils, eyeliner, eye shadows, mascaras, eye-setting powders, artificial eyelashes e.t.c

These sound harmless but just like almost every commercially produced item, there are so many risks to using them, especially as they often come in contact with the eyes.

Most eye cosmetics contain lead, cobalt, nickel, and chromium to mention a few, which are retained as impurities. These metals are toxic and can cause damage to the eyes.

Lead, which is used in eyeliners, eye pencils and some eye shadow can cause toxic optic neuropathy. It affects the retinal nerve fibres layers (RNFLs) and can cause visual deficits like visual acuity decrement, colour vision impairment and visual field defects, as shown by studies.

Cobalt and its salts are used to give eye shadows and other eye cosmetics their bright colour and cobalt chloride has been proven to be a hypoxia-mimicking compound that causes hypoxia-like effects on the local retina microenvironments and induces photoreceptor degeneration.

Nickel is used because it provides glitter and shine. This metal however can cause ocular surface inflammation. Continuous daily exposure to nickel containing dust may negatively impact human cornea.

Many more metal elements used in cosmetic products cause often irreversible damage to the eyes with over-usage. Most people use eye cosmetics in one form or another daily.
Knowing these, one has to be cautious about the products used on the eyes.

Yes, they make the eyes attractive, but with these risks, are they worth it?
