Title: The Importance of Wearing Glasses with UV-Filter Protection

Introduction The sun is the main source of energy for all living things, so it is impossible to avoid sunlight completely. However, constant exposure to ultraviolet (UV) rays from the sun can cause serious harm to our skin and eyes. While some damage appears on the surface of the eye, the more serious effects occur inside the eye. This essay explains how UV radiation can damage different parts of the eye and what we can do to protect our vision. The thesis is that we should protect our eyes from the sun by wearing appropriate lenses with UV filters.

Body Many people believe that prolonged sun exposure is harmless or even healthy, and some purposely stay in the sun to get a tan. This practice can cause many problems for the skin, from sunburn to skin cancer. That is why many sunscreens and protective lotions have been developed to reduce these risks. However, far fewer people consider the importance of protecting their eyes from harmful solar UV rays.

UV radiation is commonly divided into three types: UVA, UVB, and UVC. UVC rays are the most dangerous but are mostly absorbed by Earth’s atmosphere and do not reach the surface. UVB rays are less energetic than UVC but are not fully filtered by the atmosphere; they can cause sunburn and contribute to skin cancer, especially after prolonged exposure at places such as the beach. UVA rays are the least energetic but can penetrate more deeply. Although UVA is less harmful to the skin than UVB, prolonged exposure to UVA can cause eye problems such as cataracts, pterygium (a fleshy growth on the eye), and retinal damage.

Therefore, it is necessary to protect our eyes by wearing glasses or lenses that block UVA and UVB radiation. Options include photochromic lenses (which darken in sunlight) and polarized lenses (which reduce glare). These devices help prevent UV-related damage but cannot cure injuries that have already occurred, so prevention is essential.

Conclusion Daily exposure to UV rays can be dangerous for both skin and eyes. Because UVA and UVB can cause serious eye damage, we should protect our eyes by wearing sunglasses or lenses with UV filters, such as photochromic and polarized lenses.

Notes and suggestions

• Thesis clarity: I made the thesis explicit in the introduction and tied conclusions to it.
• Common errors corrected: grammar (verb forms, articles, plurals), spelling (e.g., “prolonged,” “effectively,” “pterygium”), punctuation, and word choice (e.g., “cause” vs. “causes,” “wearing” vs. “using” when referring to glasses).
• Suggestion: Add one or two cited sources (e.g., WHO or American Academy of Ophthalmology) if this is for a formal assignment to support claims about UV effects on the eye.

If you’d like, I can mark the exact changes in your original text, create a vocabulary list from the essay, or make a shorter version for a presentation. Which would you prefer?

Good — below is concise, targeted feedback on your essay, grouped by category, with concrete suggestions and examples.

Strengths

• Clear topic and purpose: advocating eye protection from UV is explicit.
• Logical structure: introduction, body, conclusion present.
• Use of specific terms (UVA/UVB/UVC, pterygium, photochromic, polarized) shows good subject knowledge.

Spelling and word formation (errors and corrections)

• couls → could(s)
• harma → harm
• afforted → afforded (but better: “addressed”)
• demaged → damaged
• appropiate → appropriate
• prologued → prolonged
• carcinogenics → carcinogenic (or “carcinogenic agents”)
• effectivily → effectively
• cataracs → cataracts
• photocromic → photochromic
• polarizer → polarizing (or “polarized lenses”)
• it´s → it’s (but prefer “its” where appropriate)
• many plural/article issues: “the sun is the main source of energy for the living beings” → “…for living beings” or “all living things.”

Grammar and sentence-level issues

• Article use: “the sunlight” → usually “sunlight” without “the.” “the UV rays” → “UV rays” or “the UV rays” depending on context.
• Verb forms/infinitives: “we can not to get rid of the sunlight” → “we cannot get rid of sunlight.”
• Subject-verb agreement: “this last one are the most dangerous” → “the last type is the most dangerous.”
• Word order/conciseness: “In this essay will be afforded the reasons why…” → “This essay explains why…”
• Redundancy and awkward constructions: “About this last, the damages could be outside the eye, but mainly inside the eye.” → “Damage can occur both externally and, more seriously, internally.”
• Pronoun/reference: “they are mainly the called photocromic lenses” → “these include photochromic lenses” etc.
• Punctuation: remove space before commas; fix comma splices (use period or semicolon).

Vocabulary and register

• Use formal register appropriate for argumentative essays: replace informal/colloquial items (e.g., “gadgets”) with “products,” “lenses,” or “sunglasses.”
• Precision: “the letter C in UVC, stands for Cancer” — inaccurate/awkward. UVC is simply a label; don’t assert letters stand for words. Better: “UVC is the highest-energy band and is largely absorbed by the atmosphere.”
• Avoid anthropomorphizing rays (“stand for: Burn”) — instead explain effects: “UVB is strongly associated with sunburn.”
• “On the other hand” used awkwardly — use “Conversely,” “In contrast,” or simply “Meanwhile” appropriately.

Argumentation and cohesion

• Thesis: Make your thesis a clear, single sentence in the introduction: e.g., “This essay argues that wearing sunglasses with UV-filtering lenses is essential to protect the eyes from long-term damage.”
• Topic sentences: Begin each paragraph with a clear topic sentence that signals the argument (e.g., “First, UV radiation can damage the eye’s external and internal structures.”).
• Evidence and sources: Add one or two authoritative references (e.g., WHO, American Academy of Ophthalmology, peer-reviewed studies) to support claims about cataracts, pterygium, retinal damage.
• Balance claims and qualifiers: Avoid absolute statements without evidence (“UVC…the letter C…stands for Cancer”); use hedging where appropriate (“can contribute to,” “is associated with”).
• Counterargument: For stronger argumentative stance, acknowledge opposing views (e.g., “Some argue that regular sunglasses are sufficient”) and rebut them with evidence (UV-blocking percentage, standards).

Organization and clarity

• Combine short sentences into varied sentence structures to improve flow.
• Remove repetition: you repeat that UV causes skin and eye damage several times; condense and use transitions.
• Define technical terms once, then use them consistently (photochromic, polarized).

Stylistic suggestions & improved phrasings

• “The sun is the main source of energy for the living beings.” → “The sun is the primary energy source for all living things.”
• “Nevetheless the constant exposure…” → “Nevertheless, constant exposure…”
• “Many people today think that the prologued exposure to sunlight is harmless and even healthy.” → “Many people believe prolonged sun exposure is harmless or even beneficial.”
• “But this pratice could cause many harms to our skin…” → “However, this practice can cause skin damage ranging from sunburn to skin cancer.”
• “Therefore it is necessary to protect our eyes using glasses (lenses) with UVA protection.” → “Therefore, we should protect our eyes with sunglasses or lenses that block UVA and UVB radiation.”

Mechanics and formatting

• Capitalization: “this last one are…” → “This last type is…”
• Consistent terminology: use “UV rays” or “ultraviolet (UV) radiation” consistently; spell out acronym on first use.
• Paragraphing: separate introduction, body paragraphs (each on a distinct claim), and conclusion more clearly.

Final recommendation (practical rewrite steps)

1. Write a one-sentence thesis and place it at the end of the introduction.
2. Reorganize the body into 2–3 paragraphs: (a) types/effects of UV on skin vs. eye, (b) specific ocular harms (external vs internal) with evidence, (c) protective measures and limitations.
3. Add 1–2 citations to reputable sources.
4. Proofread for spelling/grammar and replace informal words (gadgets → lenses).
5. Vary sentence length and use clear topic sentences.
